Unable to Start Linux Kernel (No Error)
RSTurgay opened this issue · 2 comments
Hi there,
It won't boot when booting Linux OS via NAND Flash. I am not getting any error codes either. I am encountering this error in this card that I produced myself. I did not encounter a problem with the same image on the NUC980 ETH 2 card. Why do you think it might?

Here it waits and there is no more.
The same image file works on ETH2 Board.
you can add printk to see where hangs. For the moment, you hangs when usb-controller is starting up.
Hi,
I figured out where the problem is. Pin 121 on my own card I developed was stuck because 1.2V supply was given instead of 3.3V. Problem is solved.
Thank you for your interest.
