NXP iMX8QM can not trace to DDR by ETR TMC

MoveMOVEMove

Hi ARM:

I am using Arm development studio（Dstream debugger） trace For iMX8QM, using ETR trace to system Mem， but it Cannot work.

But it can debug by Jtag

The config is below:

In Linux Kernel, I have make the 0x880000000 reserved, and cannot visable by linux.



The Chip is broken or any other issue?

Thanks very much.

    Hi Stephen：

    Thanks for your help, 

    Arm DS version is: 

    Version: 2024.1
    Build: 202410918

    IMX8QM cannot trace to FIFO，

    It has trace in buffer，but cannot decode，when I continue running and stop，the trace buffer is change，but cannot decode. I using another debuger, Dstream ST， still cannot decode the trace buffer. 

    I will try DS 2025.1/b,

    Thanks very much.
