Hi roger,

Thanks for moving this here and posting the logs.

Looking at everything other than the sample streaming that times out, I see nothing in the register accesses that jumps out as being suspicious or invalid.

If I understand correctly, you're concerned that the hardware is damaged, and the last thing you were doing were doing was writing some code with libbladeRF. Is that correct?

While I'd expect that setting the samplerate higher than the recommended max sample rate would yield invalid samples (when sampling via the LMS6002D), I would not expect this to have damaged the device. For the sake of confirming this, I did likewise on a board here and have been running it for a while without seeing this behavior.

Could you try to answer a few of the following just to see if we can rule anything out?

(1) You already noted trying a couple different USB ports. Could you confirm both USB 2.0 and 3.0 ports, if available?
(2) If you are able to test the board on another host machine, could you do that? (Rule out host-specific problems and test if problem follows the hardware.)
(3) I see you are using the Cypress driver backend. Could you try re-installing with the libusb backend and re-running the test. (Looking to check if the issue is driver-related).
(4) If you're willing to try booting the GNU Radio Live Image, we can have you run the same test there. (Further try to rule out OS-specific issues).

You mentioned working with the API when the device stopped working. Are you able to share the code you were working on? Were there any other failures you were seeing prior to this?

Based upon what other information you can dig up, we can figure out where to go next.

Best regards,
Jon

Hi Jon,

My concern is just that it no longer works :)

I just updated libbladeRF and switched to the libUSB driver. The CLI test doesn't seem to complain about a timeout anymore, but the output file is still empty.

My application is also still giving a timeout. BTW I noticed bladerf_get_device_list() no longer works if the device is already open, which it did before, so something has changed in this version.

Hi Roger,

Updating libbladeRF was a good idea - we usually recommended running the latest and greatest libbladeRF, FX3 firmware, and FPGA bitstream when encountering issues, in cause you hit a known issue with a fix.

The empty file is a bit weird. If you remove the "rx wait 5s;" does it seem like it's just hanging? If you build libbladeRF from source and run CMake with -DENABLE_LIBBLADERF_SYNC_LOG_VERBOSE=ON, that will compile in extra verbose output about buffers being received and used. We could potentially have you try that and share a log.

This is an expected side effect of how we are able to walk the devices using the underlying driver; I do not believe it is related to your timeout issue. It would be ideal if both backends behaved the exact same way in this regard, and I can understand that this is a little confusing. This might be a good task to put up on the issue tracker as an Enhancement request.

Let's chat some more after you can explore some of the items I mentioned. I'd definitely suggest trying to go run the GNU Radio Live Image on another machine. If the problem follows the board, perhaps we can take a look and do some additional diagnostics here.

Best Regards,
Jon

Nope, seems to run the same and I still get the empty file.
If you build libbladeRF from source
Unfortunately I don't have a compiler on this machine.

I am going to try installing everything on a different computer and see if that helps though.
