- Amlogic S912 SoC

- 16/32/64 GB eMMC
- 40-pin GPIO connector (not Raspberry Pi compatible)
A u-boot-khadas-vim2 package is prepared.
u-boot.bin needs to be combined with proprietary blobs to create a bootable microSD card. TBD
To boot U-Boot from microSD card rather than eMMC, you may need to erase eMMC from the vendor U-Boot:
kvim2# store init 3
Careful: This erases all partitions, so make sure you back up any valuable data before.
As of U-Boot v2019.07-rc4, booting directly from USB was not working.
The Tumbleweed 5.1.7 kernel is lacking CONFIG_SENSORS_GPIO_FAN, so that the optional fan is not operating.
Due to the proprietary Amlogic tools, openSUSE OBS cannot build bootable images for S912 yet.
Extensions to meson-tools package are in progress.
As a workaround for non-working USB in U-Boot you can install Tumbleweed or Kubic from Ethernet. The installer can read from USB just fine. Quick and dirty, circumventing GRUB for simplicity:
dhcp tftpboot $kernel_addr_r linux tftpboot $ramdisk_addr_r initrd setenv bootargs 'console=ttyAML0,115200n8 usessh=1 sshpassword=linux' booti $kernel_addr_r $ramdisk_addr_r:$filesize $fdtcontroladdr
For using the serial console (pins 18 and 19 RX/TX, pin 17 GND) make sure the kernel command line includes console=ttyAML0,115200n8.
For installation onto microSD card (or eMMC) choose expert partitioning and ensure that the partition table is MBR, not the default of GPT which collides with the bootloader.
