The MSP432E411Y-BGAEVM supports JTAG programming through two different connectors. JA supports the 20-pin Arm standard JTAG programming interface, and JB supports the 10-pin Arm standard mini-JTAG programming interface. Figure 10 shows the two Arm JTAG connectors. When using an external emulator, if the emulator does not provide power to the board, apply power as described in Section 2.
