Starting with u-boot v2015.04 now it is possible to export the internal eMMC card as usb mass storage device. Just type in the u-boot command ums 0 mmc 2 and connect the board via the mini-USB connector to another computer. You can access the user partition of the eMMC card as if it is a normal USB ...

There is a mainline u-boot v2015.01-rc4 with working matrix support now. Build as usual: 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 ac...

I have rechecked the settings. In contrast to my earlier assumption the new settings are slower. But the faster settings are wrong for the 1st version boards, too. (at least if they use H5TQ4G63 sdram, what I have seen on a Version 1 board picture). As far as I can see there is no need to have two d...

For v2 this is the patch I found (or got) somewhere:[...] Not sure what implication this has because my u-boot compiled without this patch works on both revisions. Ithink I got the point now. This patch modifies the refresh cycle timing of the sdram. Of course the slower setting of the 1st revision...

In the first post of this thread I added a new patch version with proper zImage and initrd support, as requested. Save settings to make sure that relocated device tree blob ends up in low memory. A second patch was added to speed up the framebuffer.

Well, I think in mainline u-boot we should have some extra features which are not used by matrixtv. Yes, requests for additional features (like bootz) are welcome. On the other side there are size constraints for bootloaders and it is much easier to get small patches into mainline... To manipulate ...

Can you also include patch from Robert Nelson for uEnv.txt and bootz bootz support would be no problem. The default environment is designed to be small and compatible to the environment shipped with MatrixSystem_V1.0.1.0. Since there is support to save the environment to the eMMC boot partition 1 (...

Since there is no support for the Matrix board in mainline u-boot (and I could not find patches to support all Matrix features in u-boot), here is a patch with this support. This patch still uses the SabreSD machine type. @ someone from TBS: Can you please request an own board-ID (machine type) for ...
