tbs2910-from-scratch

Everything you need under one roof to get Debian Sid, and a bleeding edge kernel and u-boot running on your TBS2910 single board computer (I own v1.3 of the hardware so I can't test anything else):

  1. Wiki containing instructions
  2. u-boot patch
  3. Kernel config fragment and patch
  4. Debian bootstrap script

I'm posting this "weekend project" because I like the product. I like it because it's relatively inexpensive, low power, decent hardware that seems to have some non-zero community support (especially for Freescale's saber* dev boards which this is similar to) and it's semi-open source (the schematic and some software is released. TBS, please release the BOM and all hardware design files). Also, I hate using software that is months/years out of date.

Every once in a great while I might post binary release packages containing u-boot.imx, zImage and imx6q-sabresd.dtb

Files in this project

  • u-boot.patch
  • Patch containing changes to u-boot sources
  • linux.patch
  • Patch containing changes to the Linux kernel sources
  • matrix.cfg
  • This is a kernel configuration fragment that should be applied on top of the default linux configuration
  • fsBootstrap.sh
  • This shell script completes the Debian file system bootstraping and makes the device usable.
