Tool/software: Linux
Hi ,
We are using custum board based on AM335x. Sometime kernel booting from nand shows some kernel crash at start of the linux boot. But the device is able to boot completely. Can anyone help me to find out the issue. I'm using processor-sdk-04.01.00.06 version.
Booting from nand ...
