A couple more points: BTW, I tried the same tests on Springbank which is basically Seaboard with a slightly different PCB layout, and didn't see this issue. That leads me to suspect some timing issue interacting with the panel, which I believe is different albeit theoretically compatible resolution/scan-timing wise. Second, I first applied Tom's Tegra30 patches and tested those, then applied your LCD series. The LCD series as-is breaks compilation of the Tegra30 support. I have no idea which order Tom might apply these in, but this is a heads-up there will be conflicts and one needs to be rebased on top of the other. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
