The AML-S805X-AC is a single board computer made by Libre Computer. Quite well supported in mainline because of the manufacturer funding mainline development for this board and using mainline in official images.
This board is mostly just a stripped down version of the Libre Computer AML-S905X-CC (librecomputer-lepotato).
How to enter USB mode
You need a USB Type-A to USB Type-A cable. Libre Computer sells these with an eMMC module.
- Unplug everything from your SBC
- Plug your USB cable to the USB port next to the GPIO header
- Press the K11/Uboot button near the second USB port while plugging the other end of your USB cable to your computer
- After 5 seconds or so, release the button
lsusb, you should see something like this:
Bus 001 Device 055: ID 1b8e:c003 Amlogic, Inc. GX-CHIP
Only installing to eMMC is tested.
Use pmbootstrap to build your own image, like so:
$ pmbootstrap init # manufacturer: librecomputer, codename: lafrite
Enter flash mode and clone Libre Computer's
$ git clone https://github.com/libre-computer-project/pyamlboot -b scripts pyamlboot-librecomputer
Boot the board from USB and let U-Boot enter USB mass storage mode:
$ cd pyamlboot-librecomputer
$ ./run.sh aml-s805x-ac ums-emmc
$ pmbootstrap install --sdcard=/dev/sdb # replace `sdb` with the path of your emulated UMS
Unable to control them from userspace.
U-Boot in SPI
This board boots from SPI by default, which contains U-Boot, but you may want to use the one supplied by postmarketOS.
To do so just erase your SPI flash:
# flashrom -p linux_mtd -E
