After running osmo-trx-lms for ~10mins on a LimeSDR-mini, I am getting:

History

#1 Updated by laforge 5 days ago

the problem is reproducible here. I'm trying to figure out exactly how long osmo-btx-trx needs to run with the LimeSDR-mini, but it it will happen sooner or later (about ~1min to ~10min after start on a completely unloaded quite high-end 64bit intel system). It doesn't happen at all with LimeSDR non-mini ?!?

#2 Updated by laforge 5 days ago

Another attempt, problem appeared 52 seconds after start:

Wed Jun 13 16:17:52 2018 DMAIN <0000> LMSDevice.cpp:507 [tid=140396877776640] chan 0 recv buffer of len 2500 expect 30c2e90 got 30c328c (30c328c) diff=3fc

Yet another attempt, problem appeared after 7mins 42 secs:

Wed Jun 13 16:25:42 2018 DMAIN <0000> LMSDevice.cpp:507 [tid=140409076295424] chan 0 recv buffer of len 2500 expect 1cdfb364 got 1cdfd344 (1cdfd344) diff=1fe0

#3 Updated by laforge 5 days ago

there is no other log messages before which might be able to help us what's happening:

Wed Jun 13 16:28:52 2018 DMAIN <0000> LMSDevice.cpp:305 [tid=139743110162176] Setting TX gain to 73 dB.
Wed Jun 13 16:32:43 2018 DMAIN <0000> LMSDevice.cpp:507 [tid=139743110088448] chan 0 recv buffer of len 2500 expect ef3ef2c got ef3f328 (ef3f328) diff=3fc

The "Setting TX gain" is part of the power ramping at start-up, and almost 4 minutes later the next message is already the error message.

#4 Updated by laforge 5 days ago

bad news: I saw this once happen with LimeSDR-USB, too. Very hard to reproduce, though.
