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

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.

Regards,

Marian Koop
