Not responding B100

GNU Radio
1

Hi List,

My B100 suddenly stopped responding to UHD init.
It appears that the USB interface actually lost its ability to identify
as
a device.
Here below, you can find the output of the fedora “messages” log for
the Broken B100 as well as for a working one.

Could this be solved by re-programming the USB interface somehow?

my best regards

vince

Hi Tapiwa,

There should be object code for fixing the B100 USB interface in the UHD
tree under /host/build/utils.

cmake compiled it for you when you built the whole UHD.

The bin file to use is fx2_init_eeprom.
Use the --help option to get usage info.

You also need the suitable b100_boot.bin and b100_eeprom.bin
to be flashed into the B100.

I’m actually having those but I’m not sure whether or not they’re
the good version for your board revison.
I’m actually haning no clue on the versioning of such files.
Seeking advice from other list members on this.

Best

Vincenzo
