Hi, David, I have configured P1.1 as the BSL entry sequence. I download the "Blink the LED" example into my board, and after power-up the LED blinks. Then I pull up P1.1 to 3.3V, and power up my board again, the LED won't blink. So I think my MSP432 has entered BSL. My board is powered by a battery, and between MSP-GANG programmer and my board, the connections are as bellow: MSP-GANG programmer My board Vcc-Tool (Pin2) —————— VCC GND (Pin9) —————— GND RST (Pin11) —————— RESET UART-Tx (Pin12) —————— P1.3 UART-Rx (Pin14) —————— P1.2 When I try to use MSP-GANG Programmer Software to program my MSP432, there is an Error 23 that MCU device initialization failed. Does MSP-GANG Programmer support BSL-Mode to program MSP432? Or if the JTAG/SWD of my MSP432 has been locked, how should I update the firmware with MSP-GANG ?
