MSP430FR69721: Schematic design review

Danilo A.

Part Number: MSP430FR69721

Hi Team,

Our customer built a board with MSP430FR69721 but upon testing the board with MSP-FET430UIF it didn't worked. He shared the schematic diagram and PCB layout but I can't post here due to confidentiality reason. Can you please take a look at the schematic diagram for any possible error in the design.

Regards,

Danilo

Hi Danilo,

You can share with me via TI BOX or TI DRIVE.

Ok, based on the schematic review, it appears the JTAG signal TEST/SBWTCK is missing from the MSP430. This signal is required in order to support both the full 4-wire JTAG or 2-wire SPY-BY-WIRE programming
