Other Parts Discussed in Thread: MSP430F149, MSP430F249
I am having a problem getting the MSP-FET430UIF (USB Debug Interface) working with any of my projects. I had it working many months ago, but I am not sure why it won’t work now. Here are the specifics.
I have two USB interfaces (both V1.4a; one that I just received yesterday) and I am using them with IAR Embedded Workbench V4.20.1 and V5.10.1. I also have a parallel debug interface that works just fine. I have tried the USB interfaces with 3 different products using either the MSP430F149 or the MSP430F249. In each of these applications, I can use the parallel debug interface and successfully download and debug the project. I can then plug the ribbon cable from the parallel interface into the USB interface and get an error when I attempt to debug. The error states “Fatal error: Failed to initialize... Session aborted!”
When using the USB interface, I set the Project/Options/FET Debugger to Texas Instruments USB-IF. The USB selection is on Automatic. The Windows Device Manager shows the MSP-FET430UIF – VCP on COM3. The USB selection does not give any options other than automatic.
I am probably overlooking something very obvious, but it is not obvious at the moment.
