Mainline kernels don't change anything with the clock configuration before the "Clocking rate (Crystal/Core/MPU):" is printed. No idea about Linaro kernels; one would hope they don't act any differently in this regard. So given that the submitter is using different X-Loader and U-Boot versions: -Texas Instruments X-Loader 1.4.2-1 (Mar 22 2010 - 08:57:12) +Texas Instruments X-Loader 1.5.0 (Apr 11 2011 - 09:47:30) -U-Boot 2009.11-1 (Mar 22 2010 - 10:41:15) +U-Boot 2011.03 (Apr 20 2011 - 07:02:48) the problem is unlikely to be in the kernel. I'd suggest booting a kernel with ATAGs with the same X-Loader/U-boot versions and making sure that works. - Paul _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
