MSP430F5659: MSP Emulation tools stops programming

Part Number: MSP430F5659

Hello,

I am Working on custom MSP430F5659 based board with USB boot loader used for firmware upgrade,

I have issue with programming MSP430F5659 using FET Flasher, it was working good, untill i got error cannot write to memory 0x8000.

Board is powered and its not booting, any way to make it working?

Same time i tried connecting MSP Flasher it got connected and erased the memory and it started working as usual. So what was the problem. Can't we do the erase without using MSP flasher, since once we release the board if same issue happens what action we can take to make it working? Any suggestion???

Since its in R&D we had the programmer, But in field how to resolve this ( Just for info- We have USB boot loader in it)

Thanks and Regards,

Nitesh
