Part Number:MSP430FR2311
I have an issue for MSP430FR2311 Development Kit,
I have been used that kit for programming(SBWTCK、SBWTDIO) and read data(I2C) for external MSP430FR2311 .
But I got the some issue that can’t program the our MCU(MSP430FR2311) lately.(befrore i can program the MSP430FR2311 by kit)
Could you please assist to find out that issue. There is measure info as below picture
I couldn't measure 3.3V from RESET(SBWTDIO), i have already pull SBWTDIO to 3.3V.
Program to external MSP430FR2311 should be 4 pins(Vcc_3.3V、GND、SBWTCK、SBWTOIO)
PIN | Issue |
RESET(SBWTDIO) | Should be high power(3.3V), when couldn’t program the IC that reset pin will be low power(<1V) |
