Status
The board boots NixOS from eMMC with the downstream u-boot and Rockchip trusted boot blob. Also flashing Rockchip tertiary bootloader (**idbloader**).
Additionally image provided by firefly on the chinese download page, click on Ubuntu (GPT). The image has also been uploaded to archive.org.
The official documentation, which is a pretty good state, can be found at the wiki of firefly.
Serial console
On the board there are 3 pins which have a 2.54mm pitch, this is the debug console with the text DEBUG on it. Starting from the middle to the side of the board:
- GND (Black Wire)
- RX (White Wire)
- TX (Green Wire)
- VCC, only the silver trace point and not a pin
Baud rate is 1500000
Connect to it via:
nix-shell -p picocom --run "picocom -b 1500000 /dev/ttyUSB0"
When you build your own image, you need the following extra kernel command-line parameters to get serial output:
{
boot.kernelParams = lib.mkForce ["console=ttyS2,1500000n8" "earlycon=uart8250,mmio32,0xff1a0000" "earlyprintk"];
}
Make sure you disable other consoles (tty0) as they seem to interfere with the output.
Board-specific installation notes
Installation onto eMMC
boot parts
For booting the Image you will need the following parts:
- idbloader (rockchip proprietary)
- u-boot customized by firefly
- ARM Trusted image customized for working with uboot
The whole setup can be built by hand with the following scripts originally from user samueldr.
git clone https://github.com/makefu/ROC-RK3399-PC-overlay.git builder && cd builder
nix-build -A pkgsCross.aarch64-multiplatform.AIO-3399C.firmware
ls result/
cp result/{idbloader.img,uboot.img,trust.img} .
boot and rootfs
The latest linux kernel (4.19 and up) is working with this board. Instead of building the image yourself you can fetch the latest sd-image from hydra and dd the created images onto the separate partitions. You can find all the successful builds in hydra @ nixos:release-18.09-aarch64:nixos.sd_image.aarch64-linux
# get the latest link directly from hydra
wget https://hydra.nixos.org/build/89033499/download/1/nixos-sd-image-18.09.2227.ea0820818a7-aarch64-linux.img -O sd.img
udisksctl loop-setup -f sd.img -r
dd if=/dev/loop0p1 boot.img
dd if=/dev/loop0p2 root.img
Bringing the device into Rockchip loader mode
The board can easily be flashed by booting the device into the Rockchip loader mode. The device exposes the emmc with the rockusb protocol to a connected host pc.
To bring the device in the loader mode:
- Disconnect from power
- Connect USB-C from the board to your computer
- Hold 'Recovery' button pressed
- Connect power, wait for 2 (or more) seconds
- Short press the 'reset' button and release the 'Recovery' button afterwards
flashing all boot parts
# You should have the following files available:
$ ls *.img
boot.img root.img trust.img uboot.img idbloader.img
# enter loader or maskrom mode
nix-build -A AIO-3399C.upgrade_tool
# optional: re-flash the rockchip loader, haven't tested
# result/bin/upgrade_tool UL idbloader.img
result/bin/upgrade_tool di -u uboot.img -t trust.img -boot ./boot.img -rootfs root.img
result/bin/upgrade_tool rd # reset
Now cross fingers, the system should boot into NixOS now, the getty BAUD rate
will change to 115200.
Compatibility notes
See the Rockchip compatibility matrix. Uboot requires the Rockchip Miniloader and an arm trusted boot image.
Downstream kernel
The downstream kernel sources can be found on github at [1]. The stable kernel branch they are maintaining is 4.4, however mainline 4.19 is already work according to the Rockchip compatibility matrix.
u-boot
Firefly maintains an own u-boot fork at [2].
Firefly upgrade_tool
Firefly provides an upgrade_tool which is a modified rock-chip upgrade tool. Using the upstream tool however may result in weird errors like being unable to flash the image or being unable to erase the flash. To be sure use the archive.org mirror.
However, because the software is essentially a blob, you will need to either patchelf the thing or use steam-run:
nix-shell -p steam-run --run "steam-run ./upgrade_tool"
I tried flashing with the open-source rkflashtool (in the same repo as the
u-boot stuff), however i was unable to actually connect to the device neither in
"loader" nor in "maskrom" mode. I resorted to using the closed source blob
upgrade_tool which works directly.
Rockchip MaskROM Mode
Maskrom mode is a way to get extended privileges when flashing but you need to shorten two trace points on the board. Follow the official documentation. However the loader mode should be enough for most things.
