MSP430F5310: MSP430F5310

Part Number: MSP430F5310


We have developed custom bootloader for MSP430F5310  for customer requirement.

We are observing failure in debugger/Programmer connection failures after bootloader flashing.

Let us know safe   procedure for custom bootloader flashing.

My assumptions are.

1: custom BSL flashing requirement need to Allow Read/Write/Erase access to BSL memory

2: After BSL flashing device need to be powered off before programming wires from board to avoid accidental JTAG lock

    JTAG fuse value is stored in last BSL segment, so the (factory default) value must be (all erased) 0xFF.

    I guess that reset triggered by watchdog in software should be enough to put device in fresh working condition.
