Hello AMOL SHROTRI,

For Lauterbach and Trace32 problem, you's better contact LAUTERBACH company LAUTERBACH DEVELOPMENT TOOLS.

For LS1021ATWR, make sure there is valid RCW on the target board,  if no, you could use hard-coded RCW.

Switch settings for LS1021A TWR X3 - PROC REV 1.0

SW2 : 0x8F = 1000 1111  

SW3 : 0x61 = 0110 0001

Switch settings fro LS1021A TWR X3 - PROC REV 2.0

SW2 : 0x8F = 1000 1111  

SW3 : 0x65 = 0110 0101

To enable CMSIS-DAP you have to change SW2[8] = 0

Have a great day,
Yiping
