bladeRF-cli hangs PC hard

Post by piranha32 »

The newest version of bladeRF utils hangs the computer hard. These are the steps that lead to the crash on my system:
1. Set up the board for rx:

Code: Select all

set  samplerate 2000000
set frequency 450000000
set bandwidth 1500000
rx config n=100 file=/tmp/iq.sav format=binl
2. Start receiver with "rx start". board switches into "Running" state, but no samples are received/ File /tmp/iq.wav is created with size 0.
3. Stop the receiver with "rx stop"
4. start again the receiver with "rx start"

After the second "rx start" my computer hangs. The effect is semi-reproducible: out of 3 tries I had to reboot the machine twice. I tried FX3 images compiled from github code and downloaded from nuand.com (file latest.img from 2013-08-26 01:39). Board is connected to USB3 port.
Latest commit to github:

Code: Select all

    fx3_firmware: fix HS descriptors and increase power consumtion to 200mA
    
    This commint makes the HS (USB2.0) descriptor look exactly like the SS (USB3.0)
    descriptor.
I'm getting really frustrated. Since the time I've got my board a month ago, it worked only once: after first uploading of the fpga image. Since that time I have not been able to make it work again. Is my board defective?
