Hi Bill, Sorry to hear that you have trouble with your B205.
The B205mini is shipping with a default FX3 bootloader, that is not modified/updated by NI/Ettus. Q: * Which Linux Host OS are you using? * Are you using an NI/Ettus supplied USB cable, or a 3rd party one? * Does the plugged-in device powers up (onboard LED is lid when device is plugged in)? * Did you try USB 3.2 Gen1 ports (ports rated only for 5Gbps) instead of USB 3.2 Gen 2 ports (ports rated at 10Gbps)? * Is the behavior identical on USB2 and USB3 host ports (to simply check if the device gets detected on USB2, no USB “Y” cable should be needed)? Regarding sideloading the firmware (and bootloader). I recently was successful sideloading the standard B200 firmware (usrp_b200_fw.hex) via JTAG using an Olimex ARM-USB-TINY and OpenOCD.

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. Thanks, Bill Weedon On May 6, 2025, at 7:45 PM, Marcus D.

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.
