Debugging U-boot from nor Flash using T2081 processor

[Vimalprasad]

I am trying to debug the U-boot from the NOR-Flash location . I am using 128MB  NOR Flash.

I have flashed the U-boot.bin in the address 0xEFF40000 according to 128M NOR flash memory map.

In document No. AN4876.pdf mentioned the steps for U-boot debugging for P1010.

I have followed the steps for T2081 but I can't see the source code for debugging.

After giving the path also it not entering into code.

So, currently we are checking in the Disassembly side , there we are starting from 0xEFFFFFFC and running step by step.

We were comparing the assembly code with start.S. While allocating Initial RAM in data cache  it is switches to the Instruction TLB error at 0xEFF40960 according with system.map file.

Can you give the solution for debugging the U-boot  from NOR-flash for T2081 processor in CodeWarrior?

In the application note AN4876.pdf, please refer to section "5.2.2. Stage 1 – Debug NOR for AS0", Can you see the prompt information to ask for the source file marked in red?

If yes, please click "Locate File" to specify the path of the source code.

Please make sure the u-boot image running the target board is the latest and built from your current u-boot build environment.
