Group: Hardware/Computers/Single Board Computers/TBS2910 Matrix ARM mini PC

== 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 [https://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf IMX6DQRM.pdf] reference manual.

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.

So we are in "Boot From Fuses" mode.
