AM2634: AM2634 - CCS 20.4.1 ==> unable to debug from CCS

Part Number: AM2634

Hi TI,

I am running a multicore project where core0 is run in lockstep mode. Below is my TCM memory assignments and sections from the linker.cmd file. Initially I was not using .tcmb_data memory region and I was able to enter into debug session from CCS. However, recently, I have added some variables to .tcmb_data region after which I am not able to enter debug session from CCS as it throws below error. 
Could you please let me know how to resolve this issue as debugging from CCS is imporant to our project to run tests during development phase. And I don't see anything wrong with the TCM region memory assignment and usage.
Thanks in advance!
