Hi,

      Before, we have developed MCIMX6G2CVM05AB.

      Now, we are changing to MCIMX6Y2CVM05AB,and checking the hardware is OK.

      But, the board is booting in continuously.

      Below is the boot log, hope you can help us.

      Thanks.

Hi Jimmy

 

"prefetch abort" usually happens due to ddr errors, may be recommended to run ddr

test https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-6-7-DDR-Stress-Test-Tool/ta-p/11082...

and follow sect.3.2.1 Changing the DCD table for i.MX DDR initialization   i.MX Porting Guide

 

Best regards
