FP exception / crash in lms.c #266

Closed f4gkr closed 10 years ago

Since last updates, lib does not work anymore. example libbladeRF_test_sync --verbosity verbose -o testfile -s1M [DEBUG] RX Frequency = 1000000000, RX Samplerate = 1000000 Floating point exception (core dumped)

Can you please attach the verbosity log and the stack trace?

same with Gnuradio... feel free to ask any other test thanks

bpadalino commented 10 years ago

You said it was in some recent commits that it happened? Do you know a known good commit that it was fine, and do you feel like you could bisect to the bad commit?

f4gkr commented 10 years ago

Sorry, difficult to track exactly as I do not work on this daily... I made a git sync this morning and previous one was around 15th of may roughly... for sure this was working in mid-may.

bpadalino commented 10 years ago

Understandable.

One last thing - can you add a --lib-verbosity verbose to your libbladeRF_test_sync arguments and attach the log from that? It will be a lot more output but show us every access to the devices.

That's some interesting output.

The VCOCAP seems to be wrong. The range for that is usually a few counts, not the whole range. How are you powering the device? Do you have a barrel jack you could power it from to see if that changes the operation of the device?

f4gkr commented 10 years ago

I would say "as usual" directly through the USB cable, but I will try. I also have another board, more to come soon after the tests

usb_lms_read: 0x15 0x00 Floating point exception (core dumped) I will try now with another board

f4gkr commented 10 years ago

Works with x115.............. (was a x40 previously). I have another x40 elsewhere... I may try also. more soon

f4gkr commented 10 years ago

Damned :-( works also with other x40................ looks like I killed it ? What is your feeling ... looks like the LMS is no longer able to lock in fact, the issue is inside the PLL

Nuand commented 10 years ago

Uh oh - that sounds bad.

I agree with the statement that it seems the PLL isn't able to lock? Do you have an ability to see how much current the board is taking? It could be that it's trying to use too much power for some reason and is causing a brown out of the LMS?

Either way, I don't think this is a software issue. Do you mind if I close this issue?

f4gkr commented 10 years ago

Ok for closing the issue, sure. I will make the current measurement and update you. Thanks for the fast and efficient support
