Stuck at cpu regulator mode:ldo_enable when booting kernel on a custom board

Question asked by Xavier Boucher on Apr 23, 2014
Latest reply on Jun 22, 2014 by igorpadykov

Hi,

 

I have a custom imx6 solo board that we have developped. It is very similar to the wandboard solo (same RAM).

 

I made a custom u-boot, kernel and rootfs. When I test them on the wandboard, everything is working. But when I test on my board, I get stuck to the line "

cpu regulator mode:ldo_enable". Can somebody point me to what it could be.

Thank you.
