LS1043A Custom Board Bring up using ATF

[perumandlasairam1064]

Hi Expert,
we built bl2_nor.pbl and fip.bin using ATF firmware for ls1043a custom Board LS1043AXE8QQB.
On power on the Serial port putty log is stopping near BL33 (i.e U-boot). I am sharing the log.

Here it Entering in to  Entry point address = 0x82000000 but it's not accessing  BL33( i.e u-boot).

What might be the Problem we are not Understanding whether TF-A build Problem or U-boot problem.

Thank you

Please refer to document https://community.nxp.com/t5/Layerscape-Knowledge-Base/Debugging-ATF-and-u-boot-with-CodeWarrior-for... to debug atf and u-boot with CodeWarrior.

Probably the "Inspect(attaching to the running target)" will help the customer. Please refer to the Inspect icon marked red in attached file inspect.png. After click this icon, CodeWarrior will attach to the target board, not affect the software running on the target board.

Then the disassembly code which the target board is executing will be captured and displayed in CodeWarrior IDE, please refer to the attached file disassemble.png. 

I consider you could use "Inspect" button to get the address where the system stuck.

Then use the above document to debug BL31 or u-boot.
