Hi Team,
Our proudct is using TI-Sitra AM335x processor with below structure.
- MLO : Resides in NOR
- U-Boot : Resides in NOR
- RootFS : Resides in NAND
One of product is not able to boot due to processor is giving data abort exception while getting image or communicating with NAND.Attached file give info about boot log.
I have tried below test to check issue with other part of product.
Swap non working board NAND to working board NAND. In Result non working board started working & working board started fail.
Please give us hint for problem anaylsis.
