| Ubuntu 22.04 3rd party cable that we previously used successfully for another application with this board Yes lights orange when plugged into various USB3 and USB2 machines Not sure if we have a PC w USB3.2 Gen1 ports? Behavior is identical on both USB2 and USB3 Will look into sideloading that way. That is helpful. I found that FW that you mentioned in Guthub Thanks, Bill Weedon On May 7, 2025, at 5:47 AM, Koop, Marian via USRP-users <usrp-users@lists.ettus.com> wrote:
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:
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. Regards, Marian Koop From: Bill weedon <w...@appliedradar.com>
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.
Thanks,
Bill Weedon

There is this:
https://urldefense.com/v3/__https://www.ettus.com/all-products/jtag-fx3-cable-24/__;!!OkyjEqkqqe9UhNQ!wHMdCLrQxR5vHGjT5iYbeeS60_CDOq5dvzYi98JHJ2Q_3Nygu4JnpjgP-bgPDAFG0CBBVQM0cMQyYT1l$
There's a bootloader image here:
/usr/share/uhd/images/usrp_b200_bl.img
I don't know if that image can be programmed over JTAG, or some other image is required. 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.
