Build as usual:
- Code: Select All Code
make distclean
make tbs2910_defconfig
make -j6 u-boot.imx
This u-boot should work for all matrix board versions (unfortunately there is not much information about the new version 2.3 available - and I have no access to such board). Feel free to submit patches to the u-boot mailing list, if you need modifications (don't forget to cc: the maintainers)!
BTW: special device tree support for matrix boards is available in linux-3.19-rc1, no need to use sabresd anymore.
