that I'm booting either of these. But AFAIK no one's been able to identify exactly what it could be. I haven't had the time recentlytoquoted

so there is an extra dimension of difficulty there.Ah-ha, I reproduced your failure. If I make up a concat uImage +DTB,quoted
rather than pass them separately, it fails to boot. If you switch to mainline U-Boot (v2012.10 or later) you get support for separateimage +quoted
dtb (v2013.04 gives you bootz and zImage support). v2013.04 willalsoquoted
work out of the box for BeagleBone-Black.Just to confirm, my problems with mainline were with appended DTB also. Separate DTB and zImage work fine (at least using u-boot v2013.04.) That being said, appended DTB should still work, so there's a bug hiding someplace that needs to be found fixed. Can you guys update your tests to test appended DTB also?
What is missing here is, CONFIG_ARM_APPENDED_DTB = y CONFIG_ARM_ATAG_DTB_COMPAT = y And for the code which is required in case of appended DTB, please refer to the code "arch/arm/boot/compressed/head.S" Please __NOTE__ that these options are not enabled in default omap2plus_defconfig.
