{{Languages|rockpi4/FAQs}}

== General ==

===== Where can I buy ROCK Pi 4? =====
: Currently you can buy model B from Allnet. Check the [[Buy]] page.

===== Where is ROCK Pi 4 Model A, I can't buy it from anywhere? =====
: At the time of writing(17th, Nov), ROCK Pi Model A is still in production now. We will announce it when model A is ready to ship.

===== What's the difference between Model A and Model B? =====
: The model B has PoE header, 802.11ac wifi, bt 5.0 while the model A doesn't have. The form factor is compatible.

===== What's the prices for different models and what includes?=====
: The suggested retail price for ROCK Pi is
{| class="wikitable" border="1"
|-
! RAM
! 1GB
! 2GB
! 4GB
|-
| ROCK Pi 4 Model A
| $39
| $49
| $65
|-
| ROCK Pi 4 Model B
| $49
| $59
| $75
|}

The package includes only the main board. See the [https://ibb.co/hBu34f picture].

===== What's the lifetime of ROCK Pi 4?=====
: For ROCK Pi 4 model A and model B, we will keep manufacturing/supply/support till 2025. For ROCK Pi 4 model C, the lifetime depends on the LPDDR4 ram supply, we expect life time longer than 2023.

==Hardware==

===== How to mount M.2 SSD? =====
: We have made a M.2 extended board to put the M.2 SSD on top of ROCK Pi4. It looks like this. See picture [https://ibb.co/gjD2x0 here] and [https://ibb.co/jNtD4f here].

===== Which M.2 SSD are supported? =====
: SSD comes in different form factors, listed below

{| class="wikitable" border="1"
|-
! Form Factor
! Description
|-
| Mini PCIE
| physical not compatible
|-
| M.2 B Key
| physical not compatible
|-
| M.2 M Key
| Most of M Key SSD on the market are NVMe protocol(PCIe x4 lanes), supported, few PCIe AHCI SSD is also supported. SATA protocol(nearly none) is '''not''' supported.
|-
| M.2 B&M Key
| Some of B&M Key SSD are NVMe protocol(PCIe x2 lanes), supported. Some B&M Key SSD are SATA protocol, '''not''' supported.

|}

ROCK Pi 4 expose a M.2 M key connector, it's compatible with NVMe or PCIe AHCI protocol. SATA protocol SSD are '''not''' supported. So far what we tested:

''' Known working under bootloader(For SPI + NVMe booting) '''
* HP EX900(''B&M Key, NVMe'') ✅
* MaxMemory NVMe M.2 128G(''B&M key, NVMe''), works well ✅
* Acer AT500M ✅
* Gigabyte m.2 2280 pcie x2
* Intel M.2 NVME

''' Known working under Linux kernel but not directly in bootloader(uSD/eMMC + NVMe booting) '''
* Samsung EVO series(''M key, NVMe''), work well on ROCK Pi 4, fast speed
* KingSpec NVMe M.2 2280(''M key, NVMe''), works well
* Western Digital WD Black 500GB M.2 2280 (''model WDS500G2X0C, NVMe''), works well on Debian Stretch
* Western Digital WD Blue WDS500G1B0C
* Sabrent Rocket NVMe PCIe M.2 2280 ssd 256GB, works perfectly in Ubuntu 18.04.2 server
* Intel 660P SSD ([https://forum.radxa.com/t/m-2-nvme-intel-1tb-660p-not-reconized-on-ubuntu-server/698/16 boots with 4.4 kernel])
* Kingston KC1000 NVMe
* Kingston 240GB A1000 SSD = PHISON PS5008-E8-10
* Integral 120GB M.2 2280 PCIE NVME INSSD120GM280N
* Adata XPG GAMMIX S11 Pro 256GB (AGAMMIXS11P-256GT-C)
* Zheino M.2 2280 NVME PCIE SSD 128GB (CHN-NGFFNV2280-128)

''' Known to have issues '''
* Asgard 256GB (M key, NVMe) - Formatting fails with some FSs, performance degrades quickly, Formatting via USB and using on NVMe seems to work but reliability is questionable.
* WD Green M.2 2280 SSD 250GB, detected for formatting on usb3 but unable to read/write to SSD with MKFS.
* Kingston A2000 - requires newer kernel, eg 5.3 [https://forum.radxa.com/t/first-problem-instalation-nvme-sorry-my-english/2007/30 found in Armbian]
* Adata XPG GAMMIX S5 PCIe Gen3x4 M.2 2280 512 - kernel error
* PNY CS3030 250GB - [https://forum.armbian.com/topic/10993-how-to-boot-from-nvme-in-rock-pi-4b/?do=findComment&comment=98400 errors while booting]
* HP EX900 - [https://forum.radxa.com/t/hp-ssd-ex900-m-2-250gb-shown-as-1gb-only/2563 issue with newer kernels]

''Note'': SSD with ✅ are tested by the Radxa Team, the rest is reported by community.

===== How to solve board heat issue? =====
: We have made a giant heatsink at the bottom. You can check the picture [https://ibb.co/bzKLVL 1] and [https://ibb.co/gmRCc0 2].

===== Can I use the Raspberry Pi Camera? =====
: Yes. Currently the Raspberry Pi V2 camera, IMX219, 800Mp is supported. It works with Debian and Android. Please note that the camera is supported on Android tablet version only for now.

===== Can I use the Raspberry Pi Display? =====
: Yes. The touch and the LCD works on ROCK Pi 4. Both Debian and Android. Same as camera, touchscreen is supported on Android tablet version only.

===== Can I use the Raspberry Pi PoE HAT for ROCK Pi model B? =====
: No. The official Raspberry Pi PoE HAT is not mechanical compatible with ROCK Pi 4 model B, besides, the official Raspberry Pi PoE HAT can not provide enough power for ROCK Pi 4. We have made a PoE HAT which can provide up to 22.5W power to ROCK Pi 4. Check [[PoE_HAT]]. ROCK Pi PoE HAT also supports Raspberry Pi 3B+ and 4.

===== Is the GPIO on 40pin header 1.8V or 3.3V =====
: The GPIO is 3.3V level

===== Is there I2S on 40pin header? =====
: The I2S signal is 12/35/36/38/40 pins of the header, which is the same as Tinker Board. It should be compatible with Raspberry Pi but we haven't actually tested and DAC HAT.

===== Can I power the RockPi 4 Model B using only the USB 3.0 OTG port? =====
: No. Because with USB 3.0 OTG power from PC or power supply, the power might be not enough(the voltage is only 5V, so we need high current to meet power demand, not all USB type A are designed for big current) and it's risky when flashing the firmware from USB3 OTG. So we just don't design this feature. That's why we support USB PD or QC on ROCK Pi 4, it can increase the voltage so the current is less or with the same current but gain more power.

===== How much mA can i get from the USB 3 and 2 ports for charging or use a 2.5" disk? =====
: The upper USB3.0 OTG has one dedicated current limit control which is 1.45A. The rest USB 3.0 HOST and the two USB 2.0 HOST share a current limit control of 3A together.

==OS==

===== Can I run Windows on ROCK Pi 4? =====
: '''No.'''

===== What Android verison running on ROCK Pi? Can I install Google Play apps?=====
: Currently ROCK Pi 4 have two android 7.1 based images, Android TV interface image and Android tablet interface image. Both support Google Play Store. The Android tablet like version supports touchscreen and Camera and HDMI. The Android TV version supports HDMI. Newer Android 9 is working in progress now.

===== Can I install Android on USB 3 or M.2 SSD? =====
: Currently Android is running on eMMC and microSD card only. Running on USB3 or NVMe SSD is a little bit trouble some since the CPU can not load USB/NVME directly to boot. So we must put an external bootloader in SPI flash or eMMC or microSD card to loader the image in USB 3 or NVMe SSD. ROCK Pi 4 has reserved SPI flash on board but currently not mounted by default shipping. We are still considering it since if the program in SPI flash is corrupted, it will be trouble some for user since the SPI flash is not removable. We will work on Android running on USB 3 or NVMe SSD.

===== Do you support Armbian? =====
: We now have a preview release of Armbian image, you can download it from [[Rockpi4/downloads]]

==== How to solve board heat issue? ====
: We have made a giant heatsink at the bottom. You can check the picture [https://ibb.co/bzKLVL 1] and [https://ibb.co/gmRCc0 2].

==== Can I use the Raspberry Pi Camera? ====
: Yes. Currently the Raspberry Pi V2 camera, IMX219, 800Mp is supported. It works with Debian and Android. Please note that the camera is supported on Android tablet version only for now.

==== Can I use the Raspberry Pi Display? ====
: Yes. The touch and the LCD works on ROCK Pi 4. Both Debian and Android. Same as camera, touchscreen is supported on Android tablet version only.

==== Can I use the Raspberry Pi PoE HAT for ROCK Pi model B? ====
: No. The official Raspberry Pi PoE HAT is not mechanical compatible with ROCK Pi 4 model B, besides, the official Raspberry Pi PoE HAT can not provide enough power for ROCK Pi 4. We have made a PoE HAT which can provide up to 22.5W power to ROCK Pi 4. Check [[PoE_HAT]]. ROCK Pi PoE HAT also supports Raspberry Pi 3B+ and 4.

==== Is the GPIO on 40pin header 1.8V or 3.3V ====
: The GPIO is 3.3V level

==== Is there I2S on 40pin header? ====
: The I2S signal is 12/35/36/38/40 pins of the header, which is the same as Tinker Board. It should be compatible with Raspberry Pi but we haven't actually tested and DAC HAT.

==== Can I power the RockPi 4 Model B using only the USB 3.0 OTG port? ====
: No. Because with USB 3.0 OTG power from PC or power supply, the power might be not enough(the voltage is only 5V, so we need high current to meet power demand, not all USB type A are designed for big current) and it's risky when flashing the firmware from USB3 OTG. So we just don't design this feature. That's why we support USB PD or QC on ROCK Pi 4, it can increase the voltage so the current is less or with the same current but gain more power.

==== How much mA can i get from the USB 3 and 2 ports for charging or use a 2.5" disk? ====
: The upper USB3.0 OTG has one dedicated current limit control which is 1.45A. The rest USB 3.0 HOST and the two USB 2.0 HOST share a current limit control of 3A together.

==OS==

==== Can I run Windows on ROCK Pi 4? ====
: '''No.'''

==== What Android verison running on ROCK Pi? Can I install Google Play apps?====
: Currently ROCK Pi 4 have two android 7.1 based images, Android TV interface image and Android tablet interface image. Both support Google Play Store. The Android tablet like version supports touchscreen and Camera and HDMI. The Android TV version supports HDMI. Newer Android 9 is working in progress now.

==== Can I install Android on USB 3 or M.2 SSD? ====
: Currently Android is running on eMMC and microSD card only. Running on USB3 or NVMe SSD is a little bit trouble some since the CPU can not load USB/NVME directly to boot. So we must put an external bootloader in SPI flash or eMMC or microSD card to loader the image in USB 3 or NVMe SSD. ROCK Pi 4 has reserved SPI flash on board but currently not mounted by default shipping. We are still considering it since if the program in SPI flash is corrupted, it will be trouble some for user since the SPI flash is not removable. We will work on Android running on USB 3 or NVMe SSD.

==== Do you support Armbian? ====
: We now have a preview release of Armbian image, you can download it from [[Rockpi4/downloads]]

=== IO Voltage ===
RK3399 have three IO voltages, 1.8V/3.0V/3.3V. For ROCK Pi 4, below is the default voltage:

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.465V |
| ADC_IN0 | 1.8V | 1.98V |
| Other GPIO | 3.0V | 3.14V |

</pre>

=== GPIO number ===
Rockchip RK3399 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:

GPIO0_A0 ~ A7
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7

GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

For Rockchip 4.4 kernel, the GPIO number can be calculated as below, take GPIO4_D5 (PIN22 on 40PIN GPIO) as an example:

GPIO4_D5 = 4*32 + 3*8 + 5 = 157
(A=0, B=1, C=2, D=3)

[[File:Screenshot_2020-04-12_01-06-09.png|800px]]

To set GPIO4_D5 output

cd /sys/class/gpio
echo 157 > export
cd gpio157
echo out > direction
echo 1 > value # output high
echo 0 > value # output low

==== How to solve board heat issue? ====
: We have made a giant heatsink at the bottom. You can check the picture [https://ibb.co/bzKLVL 1] and [https://ibb.co/gmRCc0 2].

==== Can I use the Raspberry Pi Camera? ====
: Yes. Currently the Raspberry Pi V2 camera, IMX219, 800Mp is supported. It works with Debian and Android. Please note that the camera is supported on Android tablet version only for now.

==== Can I use the Raspberry Pi Display? ====
: Yes. The touch and the LCD works on ROCK Pi 4. Both Debian and Android. Same as camera, touchscreen is supported on Android tablet version only.

==== Can I use the Raspberry Pi PoE HAT for ROCK Pi model B? ====
: No. The official Raspberry Pi PoE HAT is not mechanical compatible with ROCK Pi 4 model B, besides, the official Raspberry Pi PoE HAT can not provide enough power for ROCK Pi 4. We have made a PoE HAT which can provide up to 22.5W power to ROCK Pi 4. Check [[PoE_HAT]]. ROCK Pi PoE HAT also supports Raspberry Pi 3B+ and 4.

==== Is the GPIO on 40pin header 1.8V or 3.3V ====
: The GPIO is 3.3V level

==== Is there I2S on 40pin header? ====
: The I2S signal is 12/35/36/38/40 pins of the header, which is the same as Tinker Board. It should be compatible with Raspberry Pi but we haven't actually tested and DAC HAT.

==== Can I power the RockPi 4 Model B using only the USB 3.0 OTG port? ====
: No. Because with USB 3.0 OTG power from PC or power supply, the power might be not enough(the voltage is only 5V, so we need high current to meet power demand, not all USB type A are designed for big current) and it's risky when flashing the firmware from USB3 OTG. So we just don't design this feature. That's why we support USB PD or QC on ROCK Pi 4, it can increase the voltage so the current is less or with the same current but gain more power.

==== How much mA can i get from the USB 3 and 2 ports for charging or use a 2.5" disk? ====
: The upper USB3.0 OTG has one dedicated current limit control which is 1.45A. The rest USB 3.0 HOST and the two USB 2.0 HOST share a current limit control of 3A together.

==== Can I run Windows on ROCK Pi 4? ====
: '''No.'''

==== What Android verison running on ROCK Pi? Can I install Google Play apps?====
: Currently ROCK Pi 4 have two android 7.1 based images, Android TV interface image and Android tablet interface image. Both support Google Play Store. The Android tablet like version supports touchscreen and Camera and HDMI. The Android TV version supports HDMI. Newer Android 9 is working in progress now.

==== Can I install Android on USB 3 or M.2 SSD? ====
: Currently Android is running on eMMC and microSD card only. Running on USB3 or NVMe SSD is a little bit trouble some since the CPU can not load USB/NVME directly to boot. So we must put an external bootloader in SPI flash or eMMC or microSD card to loader the image in USB 3 or NVMe SSD. ROCK Pi 4 has reserved SPI flash on board but currently not mounted by default shipping. We are still considering it since if the program in SPI flash is corrupted, it will be trouble some for user since the SPI flash is not removable. We will work on Android running on USB 3 or NVMe SSD.

==== Do you support Armbian? ====
: We now have a preview release of Armbian image, you can download it from [[Rockpi4/downloads]]

|}

The package includes only the main board. See the [https://ibb.co/hBu34f picture].

==Hardware==

==== How to mount M.2 SSD? ====
: We have made a M.2 extended board to put the M.2 SSD on top of ROCK Pi4. It looks like this. See picture [https://ibb.co/gjD2x0 here] and [https://ibb.co/jNtD4f here].

==== What M.2 SSD are supported? ====
: SSD comes in different form factors, listed below

{| class="wikitable" border="1"
|-
! Form Factor
! Description
|-
| Mini PCIE
| physical not compatible
|-
| M.2 B Key
| physical not compatible
|-
| M.2 M Key
| Most of M Key SSD on the market are NVMe protocol(PCIe x4 lanes), supported, few PCIe AHCI SSD is also supported. SATA protocol(nearly none) is '''not''' supported.
|-
| M.2 B&M Key
| Some of B&M Key SSD are NVMe protocol(PCIe x2 lanes), supported. Some B&M Key SSD are SATA protocol, '''not''' supported.

|}

ROCK Pi 4 expose a M.2 M key connector, it's compatible with NVMe or PCIe AHCI protocol. SATA protocol SSD are '''not''' supported. So far what we tested:

'''- Known working under bootloader(For SPI + NVMe booting)-'''
* HP EX900(''B&M Key, NVMe'') ✅
* MaxMemory NVMe M.2 128G(''B&M key, NVMe''), works well ✅
* Acer AT500M ✅
* Gigabyte m.2 2280 pcie x2
* Intel M.2 NVME

'''- Known working under Linux kernel but not directly in bootloader(uSD/eMMC + NVMe booting) -'''
* Samsung EVO series(''M key, NVMe''), work well on ROCK Pi 4, fast speed
* KingSpec NVMe M.2 2280(''M key, NVMe''), works well
* Western Digital WD Black 500GB M.2 2280 (''model WDS500G2X0C, NVMe''), works well on Debian Stretch
* Western Digital WD Blue WDS500G1B0C
* Sabrent Rocket NVMe PCIe M.2 2280 ssd 256GB, works perfectly in Ubuntu 18.04.2 server
* Intel 660P SSD
* Kingston KC1000 NVMe
* Kingston 240GB A1000 SSD = PHISON PS5008-E8-10
* Integral 120GB M.2 2280 PCIE NVME INSSD120GM280N
* Adata XPG GAMMIX S11 Pro 256GB (AGAMMIXS11P-256GT-C)
* Zheino M.2 2280 NVME PCIE SSD 128GB (CHN-NGFFNV2280-128)

'''- Known to have issues - '''
* Asgard 256GB (M key, NVMe) - Formatting fails with some FSs, performance degrades quickly, Formatting via USB and using on NVMe seems to work but reliability is questionable.
* WD Green M.2 2280 SSD 250GB, detected for formatting on usb3 but unable to read/write to SSD with MKFS.
* Kingston A2000 - requires newer kernel, eg 5.3 [https://forum.radxa.com/t/first-problem-instalation-nvme-sorry-my-english/2007/30 found in Armbian]
* Adata XPG GAMMIX S5 PCIe Gen3x4 M.2 2280 512 - kernel error

''Note'': SSD with ✅ are tested by the Radxa Team, the rest is reported by community.

==== How to solve board heat issue? ====
: We have made a giant heatsink at the bottom. You can check the picture [https://ibb.co/bzKLVL 1] and [https://ibb.co/gmRCc0 2].

==== Can I use the Raspberry Pi Camera? ====
: Yes. Currently the Raspberry Pi V2 camera, IMX219, 800Mp is supported. It works with Debian and Android. Please note that the camera is supported on Android tablet version only for now.

==== Can I use the Raspberry Pi Display? ====
: Yes. The touch and the LCD works on ROCK Pi 4. Both Debian and Android. Same as camera, touchscreen is supported on Android tablet version only.

==== Can I use the Raspberry Pi PoE HAT for ROCK Pi model B? ====
: No. The official Raspberry Pi PoE HAT is not mechanical compatible with ROCK Pi 4 model B, besides, the official Raspberry Pi PoE HAT can not provide enough power for ROCK Pi 4. We have made a PoE HAT which can provide up to 22.5W power to ROCK Pi 4. Check [[PoE_HAT]]. ROCK Pi PoE HAT also supports Raspberry Pi 3B+ and 4.

==== Is the GPIO on 40pin header 1.8V or 3.3V ====
: The GPIO is 3.3V level

==== Is there I2S on 40pin header? ====
: The I2S signal is 12/35/36/38/40 pins of the header, which is the same as Tinker Board. It should be compatible with Raspberry Pi but we haven't actually tested and DAC HAT.

==== Can I power the RockPi 4 Model B using only the USB 3.0 OTG port? ====
: No. Because with USB 3.0 OTG power from PC or power supply, the power might be not enough(the voltage is only 5V, so we need high current to meet power demand, not all USB type A are designed for big current) and it's risky when flashing the firmware from USB3 OTG. So we just don't design this feature. That's why we support USB PD or QC on ROCK Pi 4, it can increase the voltage so the current is less or with the same current but gain more power.

==== How much mA can i get from the USB 3 and 2 ports for charging or use a 2.5" disk? ====
: The upper USB3.0 OTG has one dedicated current limit control which is 1.45A. The rest USB 3.0 HOST and the two USB 2.0 HOST share a current limit control of 3A together.

==OS==

==== Can I run Windows on ROCK Pi 4? ====
: '''No.'''

==== What Android verison running on ROCK Pi? Can I install Google Play apps?====
: Currently ROCK Pi 4 have two android 7.1 based images, Android TV interface image and Android tablet interface image. Both support Google Play Store. The Android tablet like version supports touchscreen and Camera and HDMI. The Android TV version supports HDMI. Newer Android 9 is working in progress now.

==== Can I install Android on USB 3 or M.2 SSD? ====
: Currently Android is running on eMMC and microSD card only. Running on USB3 or NVMe SSD is a little bit trouble some since the CPU can not load USB/NVME directly to boot. So we must put an external bootloader in SPI flash or eMMC or microSD card to loader the image in USB 3 or NVMe SSD.

Aaditya: create page for LED

There are 2 LEDs on the Rock Pi 4.

=== Power ===

It is '''''green''''' in color and used to indicate power supply.

=== Status ===

It is '''''red''''' for Rock Pi 4 v1.3 and '''''blue''''' for Rock Pi 4 v1.4. Shows the status of the device.

For newer kernel, the status LED is configured as heart beat device and usually blinks on/after booting successfully.

Its function can be changed as desired.

$ cat /sys/class/leds/user-led2/trigger
none rc-feedback kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock mmc0 mmc1 timer oneshot [heartbeat] backlight gpio cpu0 cpu1 cpu2 cpu3 cpu4 cpu5 default-on rfkill0 mmc2 rfkill1 rfkill2

For example, to set it to show emmc read/write status:

# echo mmc1 > /sys/class/leds/user-led2/trigger

=== IO Voltage ===
RK3399 have three IO voltages, 1.8V/3.0V/3.3V. For ROCK Pi 4, below is the default voltage:

<pre>
| GPIO | Voltage Level | Tolerance |
| ---------- | ------------- | --------- |
| GPIO3_C0 | 3.3V | 3.465V |
| ADC_IN0 | 1.8V | 1.98V |
| Other GPIO | 3.0V | 3.14V |

</pre>

=== GPIO number ===
Rockchip RK3399 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:

GPIO0_A0 ~ A7
GPIO0_B0 ~ B7
GPIO0_C0 ~ C7
GPIO0_D0 ~ D7

GPIO1_A0 ~ A7
....
GPIO1_D0 ~ D7

For Rockchip 4.4 kernel, the GPIO number can be calculated as below, take GPIO4_D5 (PIN22 on 40PIN GPIO) as an example:

GPIO4_D5 = 4*32 + 3*8 + 5 = 157
(A=0, B=1, C=2, D=3)

To set GPIO4_D5 output

cd /sys/class/gpio
echo 157 > export
cd gpio157
echo out > direction
echo 1 > value # output high
echo 0 > value # output low

=== Additional software ===

==== OpenCV ====

There are two ways to get OpenCV. One is building OpenCV by yourself (Option one) and the other is installing opencv4.0 package (Option two).

===== Option 1: Manually build =====

Build OpenCV by yourself. See [[rockpi4/dev/install-opencv | Install OpenCV]].

===== Option 2: Install pre-built binaries =====

===== Install Ubuntu desktop =====

To use OpenCV, an OS desktop is necessary. If your ROCK Pi 4 is running Ubuntu but without desktop, you can install Ubuntu mate desktop.

$ sudo apt install ubuntu-mate-core && sudo apt install ubuntu-mate-desktop

===== Install all the recommended packages =====

Required:
$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt-get install build-essential
$ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

Recommended optional packages:
$ sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
$ sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libavresample-dev
$ sudo apt install tesseract-ocr cmake-data liblept5

Install OpenCV package:

$ sudo apt-get install opencv4.0

===== Step 3: Test OpenCV =====

To check the version of your installed OpenCV, try this:

rock@linux:~$ python
Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
