Apparently, the problem does not appear for the boards in mainline U-Boot which I listed above with the source code from our v2014.01 tag and using gcc 4.8.1 from Linaro. I can install 4.8.2, but meanwhile, can you try to build v2014.01 for these boards with your setup? am335x_evm colibri_t20_iris highbank mx53loco omap3_beagle omap4_panda paz00 rpi_b > Amicalement, > > Andreas Amicalement, -- Albert.
