Hi Zekun,

What OS is this? The log doesn't look like from Linux.

Hi Bin

Customer use Windows CE.

And this customer is the same one as this thread, which has 120uF cap missing on HW design. I am not sure if these two scenario has relationship.

Hi Zekun,

This forum doesn't support Windows CE. But please correct the hardware design first then see if the issue still happens.
