I watch the UART_RX and UART_TX pins with an oscilloscope. When I push the "GO(F9)" button, I get the signals as follows: where channel 1 (Yellow) is the UART_RX signal, and channel 2 (blue) is the UART_TX signal. As the images show, I get 9 groups of data pair. The first data pair in every group are 0xFF(UART_RX) and 0x00(UART_TX). The following data pairs after the first one in the group are all 0xFF(UART_RX) and 0x8A(UART_TX). 0xFF is the sync-byte, and it seems that MSP432 replies it with 0x00 after MSP432 receives the data bits, before the parity bit and stop bit. I don't know if BSL works correctly. The MSP GANG Programmer Software still shows that MCU device initialization failed.
