Hi team,

My customer speculated that during the test flash write, the flash at the boot loader address may be written out.

Is there any way to re-write the boot code of MSP430F5418A?

Yes, you can dump factory original BSL from the identical device and write it to device with erased BSL, with FET by SBW or JTAG interface, if JTAG fuse value (inside BSL segment) is 0000h or FFFFh.
