I am having trouble getting my Beagleboard-xm to boot when the omap3-beagle-xm.dtb is loaded by u-boot
Best I can tell, u-boot loads the kernel and the dtb file successfully but boot locks up with "Waiting for root device /dev/mmcblk0p2..." There are a number of things in the boot log that look unhealthy however directly relating to the SD card I found the following: [ 1.565521] omap_hsmmc mmc.20: unable to select pin group [ 1.571563] omap_hsmmc mmc.20: Failed to get debounce clk [ 1.577270] /ocp/mmc@4809c000: can't find DMA channel [ 1.582611] omap_hsmmc mmc.20: unable to obtain RX DMA engine channel 62 If I modify my uEnv.txt to skip loading the dtb file everything appears to load up properly. What can I do to troubleshoot the dtb? I need SGX drivers so I am stuck with the following versions: I am using the 3.7.x kernel from https://github.com/RobertCNelson/stable-kernel Ubuntu 11.10 (no longer available to download from RCN's file server) u-boot 2014.1 from http://eewiki.net/display/linuxonarm/BeagleBoard#BeagleBoard-Bootloader:U-Boot About the bootloader: Ubuntu 11.10 comes with 2013.7 but there is something wrong with the uEnv.txt and the dtb cannot be loaded and falls back on loading the kernel without it. I need to rebuild u-boot to remove the 2 second boot delay and kernel validation(boot speed is requirement of the project). The patches from RCN for version 2013.7 fail to apply properly so I am using version 2014.1 which appears to be functioning properly. full boot log: http://pastebin.com/NbsM8gq0 uEnv.txt(dtb load disabled): http://pastebin.com/NWuYSYd8 I've been banging my head against the wall for about a week now on this. Any ideas as to what I could try would be awesome!
