I've been working for the past couple days on developing an ISP strategy for use with the MSP430F5436. I was testing and debugging this when suddenly I lost the ability to JTAG connect to the processor. The firmware update strategy is given below. Any ideas?
Procedure:
(1) Prepare for flash programming received - Erase Flash Bank1.
(2) Copy received program into Bank1 (program limited to 41kB, size of Bank0; does not occupy all of Bank1).
(3) CRC check Received program in Bank1.
(4) Call Flash write routine which resides in Flash area InfoD.
(5) Erase Bank0. Copy flash program from Bank1 to Bank0.
(6) Software reset processor.
