MSP-FET: "Error connecting to the target: Unknown device" Spy-Bi-Wire connection with DRV91670

Carlos Chavez

Part Number: MSP-FET
Other Parts Discussed in Thread: DRV91670,

Hi,

I'm having issues to detect the DRV91670 using MSP-FET, this emulator tool (MSP-FET) is detectable by de Code composer Version 12, but it doesn't detect the driver.

I based in this question for the connections: MSP430FR5849: MSP-FET430UIF Spy-Bi-Wire connection - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums

And also notice this information:

MSP-FET: No USB FET was found - Can't reflash DRV91670T using CCSv6.1.2 - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums

If you could provide me some feedback for this by email like the posted question above it will be very helpful.

Thanks!

Hi Carlos,

As pointed out in the thread you linked, the MSP-FET does not support the DRV91670. Only the old MSP-FET430UIF can support debugging the DRV9x device family in CCS.

Officially, the MSP-FET430UIF supports the DRV9x devices up to CCSv6, and it requires a custom patch/DRV9x SDK to be installed over CCSv6.

Since these are legacy devices that we no longer promote actively for new designs, I will reach out to you via email for more specific information.

Regards,
Eric C.
