'Debug port fail' while accessing T1022 using Lauterbach Trace32

vgupta1 — Thu, 09 May 2019 10:45:26 GMT

Hi, I am using T1022 in my design and I am trying to access processor via Lauterbach tool Trace32 power view. But I am encountering the error: 'debug port fail' or 'CPU setting: 2 cores, detected: 1 core. Check your CPU settings '. The tool is able to read SVR and PVR and also reading the correct processor using diag command. Also, the processor is successfully coming out of reset by driving HRESET high and ASLEEP high to low, hence indicate that PLLs are also locking. We have set hardcoded RCW to 0x9E configuration. Attached is the Trace32 message dump.

Please suggest what may be the issue.lauterbacht1022
