MSP-TS430RHA40A: Problem using SBW with MSP-FET

Part Number: MSP-TS430RHA40A
Other Parts Discussed in Thread: MSP430FR5739, MSP-FET, MSP430FR5738,

Hi,

I have a weird problem when trying to flash/program the MSP430FR5739 using SBW with CCS. The devkit JP4 to JP9 being placed on 1-2 for SBW. C5 is DNP. The program only flashes with JTAG or an older version of the MSP-FET.

I have two versions of the MSP-FET, the latest edition with serial 1805002D7 has an issue when trying to flash the code using CCS, I am getting:

"Error connecting to target: unknown device" (only when using SBW)

The older version of the MSP-FET is uploading the code, but it is not always able to connect. Sometimes it refuses to connect at all.

Fore more information the JTAG is working fine, I need SBW to work and I am not sure what is causing the issue, I have a prototype that is using the MSP430FR5738 and it is having exactly the same problem.

Hi Ali

Why you put C5 to DNP? You can put a 2.2nF capacitor to have a try.

Hi, according to this post this is a problem with the MSP-TS430RHA40A.

The devkit did not come with any C5 in the box. For reference my other design is having the exact same problm with 2.2 nF being installed. I am attaching the schematics so you can have a look.

In that post the problem has not been unresolved, do you have any workarounds?

Hi Ali,

Have you place the JP1 on 1-2 for power supply?

Hi,

Yes, I have tried JP1 on 1-2 for FET tool power and also 2-3 for external power. The behaviour is the same.

For reference, the older version of the MSP-FET (V1.2) without CE sticker works with both configurations.

See the attached image for the setup and the two versions of the MSP-FET.

Do you have any workarounds? My other system has only SBW, and I would like to use V2 of the MSP-FET with both.

(The unconnected one (V1.2) is working fine)

Hi Ali

For this issue is related with the new version of the MSP-FET. We will update the MSP-FET's firmware in the future. Could you send me your email address and I will inform to you when we get update with the firmware. Here will close this thread first.

Best regards
Gary
