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, according to this post this is a problem CCS/MSP430FR5739: Unable to program using newer debuggers MSP-FET - MSP low-power microcontroller forum...
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,
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)
