Introduction
The TBS2910 Matrix ARM mini PC is an I.MX6 Quad SBC.
Upstream support
u-boot: tbs2910_defconfig Linux: imx6q-tbs2910.dts
Boot settings
The board I have has the following markings on the PCB: TBS-2910V23
The schematics don't seem to fully match as I've a switch component with 4 switches inside whereas the schematics have 8.
Hence my need to document the boot settings.
SRC_SBMR2 is at 0x020D801C according to the IMX6DQRM.pdf datasheet.
Matrix U-Boot> md.w 0x020D801C 2 020d801c: 0001 0200 ....
BMOD[1:0] are the bits 24 and 25 of that register, which are zero here.
BMOD is a register field that correspond to the BOOT_MODE settings, which are explained in the table below or the table in the "8.2.1 Boot mode pin settings" chapter of the reference manual.
| BOOT_MODE[1:0] | Boot Type |
|---|---|
| 00 | Boot From Fuses |
| 01 | Serial Downloader |
| 10 | Internal Boot |
| 11 | Reserved |
So we are in "Boot From Fuses" mode.
