MSP430F2619: BSL Programming in MSP430F2619

Part Number: MSP430F2619

Hi Team,

Currently we are using MCU- MSP430F2619.
We are planning to program the MCU in BSL mode only. Please share the necessary signals required to program the MCU.
Let use know whether this TEST signal is required for BSL Programming?

Thanks & Regards,

Karthikeyan

    Hi Karthikeyan,

    For the MSP430F2619, which has dedicated JTAG pins, the BSL is invoked using the TCK and RST pins. The required signals needed are:
    • RST/NMI: Used for the BSL entry sequence and to reset the device
    • TCK: Used specifically to trigger the BSL entry sequence
    • P1.1 (BSL TX): Transmits data from the MCU to the programmer
    • P2.2 (BSL RX): Receives data from the programmer to the MCU
    • VCC & GND: Standard power supply signals

    As far as the TEST pin, this signal is not used for BSL on the MSP430F2619. Some smaller MSP430 devices use the TEST pin for BSL entry, but the MSP430F2619 has these dedicated JTAG pins, so for this specific device family, the TCK pin replaces the TEST pin.

    Hope this helps!
