I created i.MX6Q custom board, but about a half of them hanged when Linux booting.
The attached files are log when it hanged, and we can see the stopping points are different.
Sometimes these can boot correctly, but it will hang rarely.
I'm debugging what is wrong, and checking errata, ripple of power supply, clock, DDR calibration with calibration tool in the following URL.
But I've not identified the root cause yet.
Could you advice me what should I check any other to find the root cause?
And if you can guess what is wrong by the attached log, could you let me know it?
