Hi Yuri

we find out that there is a mistake in console log of USB debug port during downloading uboot and kernel files into the device using MFG-tools. The console log is as follow.

Starting the hotplug events dispatcher udevd
udevd (1912): /proc/1912/oom_adj is deprecated, please use /proc/1912/oom_score_adj instead.

IS there any problem with the eMMC IC?

Hello,

What MFG release and what MFG configurations are used?

Regards,

Yuri.

Hi Yuri

We made two customed im6d boards.There is a little schmetic difference between those two board.One is OK.the other one can successfully download the uboot and kernel files into the imx6 device using MFG-tools.But it can't start up.

we find out that there is a difference between those two board in console log of USB debug port during downloading uboot and kernel files into the device using MFG-tools.

The good one‘ log shows "Boot device:IIC".The questionable one's log shows"Boot device:NOR".

Does it relate to the problem?

Hello,

I do not think the provided logs allow us to define exact reason of the issue.

Perhaps it makes sense to perform memory test for suspicious board.
