How to load Linux kernel image onto ARM Cortex-A9 target using DSTREAM debugger?

Amit

Hello,

        I have a custom ARM Cortex-A9 board. My aim is to load the kernel image onto the target via ARM DSTREAM. I have u-boot loaded into SNOR memory. The u-boot is running fine. After I get the u-boot prompt I am connecting to the target via ARM DSTREAM. Then I press pause button and enter the command add-symbol-file "<path>\vmlinux". After executing this command I get the message as "Cannot determine target state".

I want to know whether I am following the correct steps for the above described problem. Please let me know if changes are required and also suggest some pointers if required.

    I don't really have enough information to help you.  Can you tell me...

    • what is the full restore command you are trying?
    • what error messages are you getting?
    • what is the virtual address that your vmlinux is linked to?
    • what is the physical address you want to load it to?
    • what happens if you use a Memory view to view and write a word to that physical address?
