MPC8309 NOR u-boot fails after enabling address translation in start.s

[Sw2]

Hi ,

Cc: jothikanna@gmail.com

I am currently trying to port u-boot for MPC8309 based custom board.

I have used MPC8309som u-boot BSP as base for porting.

After building the u-boot, I have programmed the u-boot in NOR flash connected in Enhanced Local Bus (elbc).

After power on the board the serial is not displayed and the board is hung.

When I debugged the u-boot using trace32, It is observed that the target is not responding after enabling address translation in start.s ('enable_addr_trans'). Please see the attached screenshot.

After this stage all the source code line in trace32 changed to the symbol "?". (Please see the attached screenshot).

Can anyone suggest what might be the possible issues ? or any method to debug the issue.

Please see the below details as well.

RCWLR : 0x4206_0043, RCWHR : 0xA460_0000

U-boot.bin flashed location : 0xFFF0_0000.

Exception vector address: 0xFFF0_00100 (start.s execution starts from here)

Expecting your kind reply.

Thanks
