Hi all,

 

I'm using LS2085AQDS Board with EAR5 images.

 

Default images only i flashed. Sometimes in uboot it throws synchronous abort handler error prints and hanging there itself. If i restart after sometime, its working fine.

Per day it throws 4 to 5 times. This is because my work is getting delay.

 

I want to know why this error is occured and how to resolve it ?. I tried to trace in uboot code. But i can't get exact reason of that.

 

If anyone know about this issue. Please help me on this. 

 

Boot log is as follows (error ptint is highlighted):
