ROCK Pi soporta el modo de máscara rom, 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 4 mainboard
* SPI flash soldered on ROCK Pi 4
* 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. [https://forum.radxa.com/t/otg-flashing-not-working/717 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 [https://brew.sh/ 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 ===

==== Empty SPI flash ====

To boot ROCK Pi into maskrom mode is simple, you don't need to press any key

* Power off the board and '''remove any bootable storage media''', remove microSD card, remove eMMC module.
* Plug the USB Male A to Mail A cable to ROCK Pi 4 OTG port(the upper USB3 port), the other side to PC
* Power on the board

==== Update SPI FLash with bootloader inside ====

If the SPI flash already contains a bootable bootloader, you need to disable the SPI flash at boot time by shortcut the SPI1_CLK to GND. Use wire to connect PIN '''23''' and '''25'''. Checkout the [https://wiki.radxa.com/Rockpi4/hardware/rockpi4#gpio Pinout].

Shown as following:

[[File:Spi_clk_gnd.jpg | 500px]]

* Use cable to connect PIN23 and PIN25
* Power off the board and '''remove any bootable storage media''', remove microSD card, remove eMMC module.
* Plug the USB Male A to Mail A cable to ROCK Pi 4 OTG port(the upper USB3 port), the other side to PC
* Power on the board
* Remove the cable and disconnect PIN23 and PIN25

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 we can proceed the next step to flash.

=== Write to SPI flash via USB ===
On your PC, run the rkdeveloptool

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

Download the '''SPI loader''' (flash helper, important) to init the ram and prepare the flashing environment etc. If you don't have it, you can download it from [https://dl.radxa.com/rockpi/images/loader/ here]

rkdeveloptool db rk3399_loader_spinor_v1.15.114.bin

Write the packed SPI image of u-boot and trust.img, start to write from offset '''0'''.

rkdeveloptool wl 0 /path/to/uboot-trust-spi.img

Reboot the device

rkdeveloptool rd

Now the device should boot from the SPI flash now.

=== Troubleshooting ===

* If you have issue with flashing via USB OTG, start a new post on the forum. https://forum.radxa.com/c/dev
