Hi Mehul,
Can you confirm this option is enabled in your SYSCONFIG? It seems to be that SWD was not enabled.

As it mentioned in Readme file of example code of secondary bootloader once this code loaded in device only sec bootloader is active and default bootloader is inactive and to revert this we need to do factory reset. So my question is if secondary bootloader is in device SWD is not working? is it not possible to load program again using debug port?

Hi Mehul,
I haven't heard that a secondary BSL could prevent the SWD from working unless NON-MAIN is modified incorrectly or SWD is not enabled. I recommend first installing the latest version of CCS, the M0 SDK, and SYSCONFIG, then trying a different secondary bootloader example and seeing if the error persists.
