CCS/AM4372: JTAG connect issue

Part Number: AM4372

Tool/software: Code Composer Studio

Hi,

I'm using AM4372 in our custom board. Having PMIC problem in board [mentioned & waiting for support rom link : https://e2e.ti.com/support/power-management/f/196/t/862729].

meanwhile, thought to remove PMIC IC & fed the DC supply rails (1.1V, 1.1V, 1.35V, 3.3V, 1.8V) externally using bench top DC power supplies.

Now processor is ON, but JTAG couldnt take control over board. JTAG "test connection" passes in CCS. but with any project debugging, loading the binary itself fails with below mentioned errors.

These errors continuously comes & stops me from further progres. Any idea what is missing? Thanks in advance.

BR,

Anantha R

    Anantha,

    Since you are in a scenario where there is a big chance the processor is in an unstable state, I would perform a manual launch of the debugger and check the status of the cores.

    The manual launch is shown in section 7.3.2 and the core status is shown in section 7.5.7 of the CCS User's Guide, available in the CCS help (menu Help --> Contents). Alternatively it is also available at the link below:

    https://software-dl.ti.com/ccs/esd/documents/users_guide/index.html

    This will give you further insights about the root cause of the problem. 

    Hope this helps,

    Rafael
