iMX6 Sabreai Auto Eval Board login failed

shijiaguo · ‎08-12-2016

Hello,

I have an iMX6 sabreai quad automotive eval board. I've built the kernel with an console only image. I downloaded the image to SD card and it booted ok. I can log in with just the username root. However today I was trying to boot with NFS, and ever since I configured that, I log in with root, yet it prompted me with a password request. What do I put in for this password? Any idea?

Here's my uboot config:
