Hello,
In my quest for the state of graphics support on Tegra, my AC100 is still running a bit unstable with marvin24's for-next branch and fbdev only, but I made progress getting our support for the Colibri T20 into a cleaner state: Tegra uses yet again a different binary from u-boot.bin and u-boot-dtb.bin, u-boot-dtb-tegra.bin, with a prepended SPL. Flashing it without the SPL, there was no serial output on boot-up.
With the correct U-Boot binary, output ended in "Starting kernel ...". It turned out that Tegra support apart from, e.g., DRM drivers was missing completely, including serial driver, with default being ttyAMA0. I've branched the KOTD and can hopefully tomorrow test the attached config as far as one gets without initrd. BTW I also noticed some apparent inconsistencies wrt Zynq support, but I'll leave that until me or anyone receives such a board for testing. :) Andreas -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg
