We have a problem showed below:
1> Schematic is based on MCIMX6Q-SDB;
2> Chip : MCIMX6Q5EYM10AD
1> One board(new board) can boot to serial download mode and download the image; Then, configuring the board to boot from fuse in eMMC(have been configured), but the board will still boot to serial download sometimes(not always, maybe happens one in two hundred times).
2> We replaced another chip(the same type), then the problem will not happen again.
3> We doubt that the chip is damaged before, but can't find the reason.
Hope to help us to analyze.
Thanks a lot.
