< RockpiN10‎ | dev
    ROCK Pi N10 >  Development >  Install from USB OTG 

ROCK Pi N10 comes with on board eMMC, you can install images to eMMC with USB. The installation is running in maskrom mode, which is a special running mode the CPU is waiting for command from USB OTG port. The PC tool we use to communicate with ROCK Pi in maskrom mode is rkdevelop tool, an open source tool by Rockchip.

Requirement

  • ROCK Pi N10 main board
  • Power adapter
  • USB Male A to Male A cable(important) USB-C has been seen as not working, an adaptor for USB-C to USB-A has worked. See discussion.

Make sure rkdeveloptool is set up on host computer

Linux

To build rkdeveloptool on a debain based Linux distribution, follow the instruction below:

Install build dependecy:

 sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf

Clone the source code and build:

 git clone https://github.com/rockchip-linux/rkdeveloptool
 cd rkdeveloptool
 autoreconf -i
 ./configure
 make

If you encounter compile error like below

   ./configure: line 4269: syntax error near unexpected token `LIBUSB1,libusb-1.0'
   ./configure: line 4269: `PKG_CHECK_MODULES(LIBUSB1,libusb-1.0)'


You should install pkg-config libusb-1.0

   sudo apt-get install pkg-config libusb-1.0

Then re-run

   autoreconf -i
   ./configure
   make

Now you have rkdeveloptool executable at the current directory.

 sudo cp rkdeveloptool /usr/local/bin/

MacOS

To build rkdeveloptool on macOS, you need homebrew(or similar package manager) to install required packages.

Install build dependency:

   brew install automake autoconf libusb

Clone the source code and build:

   git clone https://github.com/rockchip-linux/rkdeveloptool
   cd rkdeveloptool
   autoreconf -i
   ./configure
   make

If you encounter compile error like below

   ./configure: line 4269: syntax error near unexpected token `LIBUSB1,libusb-1.0'
   ./configure: line 4269: `PKG_CHECK_MODULES(LIBUSB1,libusb-1.0)'


You should install pkg-config libusb-1.0

   brew install pkg-config

Then re-run

   autoreconf -i
   ./configure
   make

Now you have rkdeveloptool executable at the current directory.

   sudo cp rkdeveloptool /usr/local/bin/

Boot the board to maskrom mode

To boot ROCK Pi N10 into maskrom mode is simple since we have the maskrom key on board.

  • Power off the board and remove any bootable storage media such as microSD card. If you have bootloader in SPI flash, you need to shortcut SPI flash first as picture below. Or you can erase SPI fist.

  • Plug the USB Male A to Mail A cable to ROCK Pi N10 OTG port(the front USB3 port), the other side to PC

  • Power on the board
  • Press and hold the maskrom key, short press the reset key

  • Release the maskrom key

Now on your Linux PC, lsusb command show show the following usb devices

   Bus 003 Device 005: ID 2207:330c

It means the device is in maskrom mode now.

  • Now plug the eMMC module and proceed the next step to flash.

Install to eMMC via USB

On your PC, run the rkdeveloptool

   rkdeveloptool ld        # List the device
   DevNo=1	Vid=0x2207,Pid=0x330c,LocationID=305	Maskrom

Download the loader (flash helper) to init the ram and prepare the flashing environment etc. If you don't have it, you can download it from here

   rkdeveloptool db rk3399pro_loader_vxxxx.bin

Write the GPT image to eMMC, start to write from offset 0.

   rkdeveloptool wl 0 /path/to/rockpin10-xxx-gpt.img

Reboot the device

   rkdeveloptool rd

Now the device should boot the new image on eMMC

Install by partitions(optional)

Sometimes we only want to update a partition of the image, for example only the boot partition to update kernel only. We can flash by partitions

| Part Number | Offset | Name    | Description                |
| ----------- | ------ | ------- | -------------------------- |
| 1           | 32KB   | loader1 | First stage loader         |
| 2           | 8MB    | loader2 | U-boot image               |
| 3           | 12MB   | trust   | ATF                        |
| 4           | 16MB   | boot    | Kernel partition, bootable |
| 5           | 128MB  | rootfs  | Rootfs                     |

When the board is in maskrom mode, flash the partitions with the following command and offset:

   rkdeveloptool db rk3399pro_loader_*.bin
   rkdeveloptool wl 64 idbloader.img
   rkdeveloptool wl 16384 uboot.img
   rkdeveloptool wl 24576 trust.img
   rkdeveloptool wl 32768 boot.img
   rkdeveloptool wl 262144 rootfs.img
