Hi All,

I am facing following crash while trying to boot kernel uImage:

U-boot branch: imx_v2014.04_3.10.53_1.1.0_ga

Kernel: 3.10.72 (3.19.53_1.1.0_ga + Stable Updates)

I am successfully able to boot the zImage. The problem is only when trying to boot uImage.

Everything works fine when I use u-boot from branch imx_2014.04_3.10.31_1.1.0_beta branch. I have tried to root-cause the issue, I have tracked down to one-commit "404fd02 ENGR00326277-1: imx6: ldo_bypass: fix VDDARM voltage setting violate datasheet", which might be causing the issue. Can you please help further debugging and root-causing the issue.

Hi khandavalli

had you tried with Demo images

L3.10.53_1.1.0_iMX6QDLS_Bundle : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite,

i.MX 6Solo Linux Binary Demo Files and Linux BSP Documentation

Best regards
