MSP432P401R: BSL replies invalid Core Response over I2C requests

Part Number: MSP432P401R

Hi ,

I am trying to communicate to MSP432 BSL over I2C Comms, but am getting a default response which looks to be invalid.

The Chip is correctly entering into BSL and able to write onto the Slave address 0x48(default set), but the response seems to be wrong.

for example this is a I2C write Packet (TX BSL Version) -  80 01 00 19 E8 62

In response I get - 00 80 02 00 00 00 0F 1D*

For other commands even I get the exact response back.

At another time had tried with a Debug BSL, using CCS, I did get a correct response back.

Note:- there are no code changes for Debug build vs the Release build

Please let me know If I am missing any configuration here.

Thanks
