FPGA code not loading: 'unexpected error' ?

The file is there, bladrf-cli works in both interative and batch mode, bladeRF is seen as device. Merely FPGA volition not load:

#bladeRF-cli -b -l ./hostedx40.rbf
Loading fpga...
Error: failed to load FPGA: An unexpected error occurred
Could not load fpga

Any hints?

Hi,

yes, its the correct fpga version. I rebuilt with debug but doesnt really help me much:

# bladeRF-cli
[DEBUG /root/sandbox/bladeRF/host/libraries/libbladeRF/src/backend/libusb.c:249] Found a bladeRF
[DEBUG /root/sandbox/bladeRF/host/libraries/libbladeRF/src/backend/libusb.c:315] Claimed all inferfaces successfully

[DEBUG /root/sandbox/bladeRF/host/libraries/libbladeRF/src/backend/libusb.c:219] Change to alternating interface 0

Fault: An unexpected error occurred

bladeRF>

Potentially important fact: I'thousand running on a Parallels VM Ubuntu on a MacBook. Seeing as the last error message is from libusb, there might be something fishy with the USB3 support in VM'south??

I am also seeing the same behaviour on a native Mint install and then I doubtable this may not be a VM result:-

I now have it working :D

I re-built the FX3 FW from source, flashed that and it then flare-up into life.
I then tried re-flashing the latest.img downloaded from naund.com and approximate what ? that worked too.

Then I guess something must have gone wobbly during the update from V1.0 to V1.i

If you invoke the CLI equally such:

Y'all should get more information. We just change the logging machinery over the weekend to be more than granular. Y'all should come across a lot more than debug messages coming out.

Also, exist certain to check the Wiki regarding setup on Ubuntu - we've had a lot of reported success with that.

Let usa know how it goes.

Hello,

I built the FX3 fw from source, just like previous poster, and flashed that succesfully, but it still wont accept any fpga code.
bladeRF-cli -i -v debug doesnt do much, merely cloned the git repo and built again. But no more info than previously:

# bladeRF-cli -b -fifty hostedx40.rbf
[DEBUG /root/sandbox/bladeRF/host/libraries/libbladeRF/src/backend/libusb.c:249] Constitute a bladeRF

I'll endeavour on a native linux auto tonight and update here......

Ok, so I tried on a native linux machine (merely it but had USB2.0) and I could flash the FPGA code.

I and then went back to my Ubuntu VM, and switched off USB3.0 support in Parallels. I was and then also as well able to load the FPGA code. Switch dorsum on USB3 support and no FPGA load possible. And then I tin can confirm this is a USB outcome.

At present struggling to become some usefull output from the device, but take gqrx running with information technology....

Thanks!!
