switch to ldo_bypass mode!

(这里的ldo_bypass作用是什么，并且还是用到了i2c,

如果我把UBOOT里的设置ldo_bypass删除，可以正常引导内核，内核会卡在Galcore version 5.0.11.25762这句话)

Hi Qiang

are you able to boot with ldo enabled - using xxx-imx6q-sabresd-ldo.dtb ?

If yes - then probably you are having PMIC problems - please check

that it can be controlled by processor.

If not - then probably you have ddr errors and one needs to run DDR test

and update memory settings. Recommended to use FSL BSP

L3.10.53_1.1.0_iMX6QDLS_Bundle

Best regards

igor
