| − | It can boot the image provided by firefly on [http://www.t-firefly.com/doc/download/54.html the chinese download page], click on '''Ubuntu (GPT)'''. The image has also been uploaded to [https://archive.org/details/AIO-3399C archive.org].

| | | | |
| − | The official documentation, which is a pretty good state, can be found at [http://wiki.t-firefly.com/en/AIO-3399C/ the wiki of firefly]. However as of right now i was unable to:
| + | ''— samueldr, Lead of NixOS on ARM.'' |
| − | | |
| − | * build an nixos image which can be booted as root image from the emmc (root image must be build as "android" boot)
| |
| − | * build an sd-image with a kernel which detects the card at stage one with NixOS (cannot find rootfs)
| |
| − | * build the the bootloader with NixOS (blobs and trustedboot comes from rockchip)

| − | == Board-specific installation notes ==
| |
| − | | |
| − | == 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 <code>1500000</code>
| |
| − | Connect to it via:
| |
| − | <syntaxHighlight lang=bash>
| |
| − | nix-shell -p picocom --run "picocom -b 1500000 /dev/ttyUSB0"
| |
| − | </syntaxHighlight>
| |
| − | | |
| − | When you build your own image, you need the following extra kernel command-line parameters to get serial output:
| |
| − | <syntaxHighlight lang=nix>
| |
| − | {
| |
| − | boot.kernelParams = ["console=ttyS2,1500000n8" "earlycon=uart8250,mmio32,0xff1a0000" "earlyprintk"];
| |
| − | }
| |
| − | </syntaxHighlight>
| |
| − | == Compatibility notes ==
| |
| − | See the [http://opensource.rock-chips.com/wiki_Status_Matrix 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 [https://github.com/FireflyTeam/kernel]. The stable kernel branch they are maintaining is <code>4.4</code>, however mainline 4.19 should already work according to the [http://opensource.rock-chips.com/wiki_Status_Matrix Rockchip compatibility matrix].
| |
| − | | |
| − | === u-boot ===
| |
| − | Firefly maintains an own u-boot fork at [https://github.com/FireflyTeam/u-boot]
| |
| − | | |
| − | === Flashing via Rockchip Loader Mode ===
| |
| − | The board can easily be flashed by booting the device into the Rockchip ''loader'' mode.
| |
| − | | |
| − | 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
| |

| − | ==== Firefly upgrade_tool ====
| |
| − | Firefly provides an <code>upgrade_tool</code> which is a modified [http://opensource.rock-chips.com/wiki_Upgradetool 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 [https://archive.org/details/AIO-33399C archive.org mirror].
| |
| − | | |
| − | However, because the software is essentially a blob, you will need to either patchelf the thing or use '''steam-run''':
| |
| − | <syntaxHighlight lang=bash>nix-shell -p steam-run --run "steam-run ./upgrade_tool"</syntaxHighlight>
| |
| − | | |
| − | === 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 [http://wiki.t-firefly.com/en/AIO-3399C/maskrom_mode.html the official documentation]. However the loader mode should be enough for most things.
