syslog errors, bladeRF-cli exits immediately upon "rx start"

[johnm]

No errors on build, latest master from git. Finds the board okay. Tried both shipped fx3 firmware and the latest. Tried both versions of the hostedx115 FPGA binary. I load the FPGA and the light begins blinking, and I begin the session below. Upon "rx start" it immediately exits without error.

I am running under VMWare on a Windows 7 machine. USB 3.0 is enabled in VMWare player.

Here is the device being detected:

It's probably something boneheaded. I apologize if it is. I'm new to this

Thank you,

I was having issues accessing and using the bladeRF at first as well and was having it exit out whenever I tried to run rx start. On my system only root had access to the /dev/ directory, so I couldn't get any response unless I ran the cli or gnuradio for that matter as root.

example

$ sudo ./bladeRF-cli
open /dev/bladerf0
etc.

or

$ sudo gnuradion-companion

In all reality it is probably an issue with my installation and your problem may very well be unrelated, but maybe it's worth a try.
Either way, good luck!

Having the same problem (Failed to read peripheral response) on Win8/vmware/usb2.0 using root/sudo. Any solution so far?

[syntroniks]

FWIW winktsu, I did not have any luck with USB2.0 ports, but then again, this was a few weeks ago before libusb support. I would really recommend a USB3 card for your computer.

[winkstu]

Thanks for your reply. I tried to get it working within vmware and native on win8, but no luck. In the end, I bought another pc with usb3 and ubuntu. And it works

For playing around, nevertheless, it would be useful if vmware is also supported although I do understand that this has probably not the highest priority at the moment.
