Solution for MSP430F149 BSL download program failure [Copy link]

   When using MSPFET-BSL to download MSP430f149, I always get the message "Programming failed, synchronization error, etc.". I use CH340-USB to serial port, and connect TXD/RXD (P3.4/P3.5), TCK, RST (57PIN, 58PIN), and two power supplies. I use a logic analyzer to capture the timing of TCK and RST. The timing is correct, but I just can't download the program. The 149 chip is good, and the program inside can run normally.

Using CH340, output ports: TXD, RXD, DTR, RTS, TXD <-----------> P2.2 (RXD) RXD <-----------> P1.1 (TXD) DTR <-----------> RST RTS <-----------> TCK
