You mentioned the boot configuration switch (SW6) in the commit message, but not in the README itself. Does this mean you planned to include a description of the boot switch settings (what I think would be a good idea)?For board version V2.3 the switch settings are: switch 1 2 3 4 eMMC 1 1 1 1 SD2 1 0 0 0 SD3 0 1 0 0 Loading u-boot from SATA unfortunately is not possible on V2.3 . > [...] > \ No newline at end of file Please add the newline when resending this patch.

The installation documentation make use of the "BOOT/UPDATE" mechanism that is documented in the TBS2910 OS installation manual[1]. This is to make sure that they work on the different PCB revisions of this board. There is also a boot configuration switch (SW6) but the one described in the v2.1 schematics has 8 switches whereas the one present on the v2.3 board has only 4. Only the v2.1 board schematics are available.
