Seems we’re on the right track here. $180 programming cable and I also found FX3 source code on github. Need to figure out what compiler to use to compile the FX2 code or upload the raw binary using the $180 programming cable.
I also created an NI account and sent in a service request. They quoted $450 to fix/replace the B205mini. Seems like a good deal. But since I have two boards with the same issue thats $900.

There is a utility: /usr/lib/uhd/utils/b2xx_fx3_utils That is used *when the device actually appears on USB*. In your case, "side loading" through JTAG--->FX3 is not something I have a procedure for, but, like I said, I'm trying to find out. > > On May 6, 2025, at 5:43 PM, Marcus D.
