OCRAM target memory fault

[Tao2022]

We have a customized LS1043a board, being having problem debug "Hello world" project on it with CodeWarrior (connected via CW Tap). To narrow out the incorrect DDR initialization possibility, I modified LCF (  aarch64elf.x) to make the code to be downloaded to OCRAM to run(following NXP Document AN5346.pdf), but it still complains "target memory fault.....".

I wonder there is something there to stop the elf to be debugged by CodeWarrior, doesn't matter where the elf is downloaded. Have being hanging here for a week, Please, anyone have any suggestion will be deeply appreciated.

Here is my GDB traces (with errors in red font):

Please refer to "9.2 Connection diagnostics" section in C:\Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual.pdf to perform diagnostics task on your custom board.

In this diagnostics task, "Test OCRAM memory access" action is performed.

Hi, Yiping, thanks for replying my post. I went through the connection diagnose, it shows  "Test OCRAM memory access" successfully tested address 0x10000000.
