DS-5 is able to see DAP, but nothing beyond?

Hi,

When I am configuring the platform, DS-5 is able to see all the ARM chain like this:

However after new revision of code is released(NOTHING in ARM is touched), now I am only able to get this:

I used to seen the situation where the DAP is not even observed, and that was when something is wrong with ARM connection inside FPGA. But I don't understand how come that DAP is OK but the chain does not show up.

I am new to FPGA emulation and DS-5, so many thanks to anyone that help!

Regards

Nicole

    I am facing the same problems as you wrote.

    info: Opening the debug pre-connection to device 1

    info: Connecting to the DAP

    info: Detecting AP buses

    info: DAP_CONFIG_INFO = 1,00:H

    Could you give more detail instructions how to solve this one? I actually don't understand what to do with this

    "The AP-BASE register on the debug APB must be correctly pointing to the start of the CoreSight ROM table on the debug APB. I believe the default address is 0x80000000 for the ROM table." I am just new to FPGA and DS-5. Many thanks to you that give more instructions!
