I have a BBxM board and try to boot with power from 5v plug-in. However, my BBXM cann’t read uSD card and repeat booting again and again. When I try using OTG USB port with 5v outside to power the board, then It can boot and run fine.
Have you ever seen this problem, how to solve it ?
I guess somthing wrong happen to voltage regulator supply to uSC card reader from 5v plug-in on the board, but I dont know how to check it.
Can you give me some solutions ?
Thank you !
