LimeSDR utilities on FreeBSD
GQRX + LimeSDR Mini.
- TODO
LimeSuite FreeBSD Port.
- [DONE] source port
portsnapand binary packagepkgavailable for everyone. - [DONE] commit to port tree: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252032.
- [DONE] LimeSuite + SoapySDR module build.
- [ONGO] build fix / patch upstream.
- [ONGO] cmake: https://github.com/myriadrf/LimeSuite/pull/329.
- [ONGO] wxString debug: https://github.com/myriadrf/LimeSuite/pull/332.
- [ONGO] connection remote: https://github.com/myriadrf/LimeSuite/pull/333.
- [ONGO] stream unit constructor: https://github.com/myriadrf/LimeSuite/pull/336.
- [ONGO] stream unite header: https://github.com/myriadrf/LimeSuite/pull/337.
- [TODO] less verbose console output even for GUI application.
- one way to control LibUSB verbosity is using environmental variables like <code>LIBUSB_DEBUG=0 LimeSuiteGUI</code>.
- [DONE] compiler/linker errors in the Lime Suite (which contains more than the SoapySDR driver).
Known problems
Software / Utilities
LimeSuite and SoapySDR cannot open LimeSDR USB device while detect works fine.
- [ONGO] problem fixed. upstream / firmware updated.
- [TODO] make solution public.
- [TODO] verify the solution.
- [TODO] fix the device open problem.
- [TODO] unable to open usb device - find a cause of the problem - probably a LibUSB reset related.
- [DONE] Create LimeSuite port for FreeBSD.
wx assertions on application startup.
- [TODO] problem fixed. upstream / firmware updated.
- [TODO] cause found.
- [DONE] report issue on upstream github, done: https://github.com/myriadrf/LimeSuite/issues/338.
Software / OS / FreeBSD
Excessive debug output.
- [ONGO] problem fixed. upstream / firmware updated.
- [TODO] make solution public.
- [TODO] verify the solution.
- [TODO] fix the device open problem.
- Likely setting the verbosity level to a different value in FreeBSD could fix the issue, as maybe libusb on FreeBSD is just more verbose, but I’m not sure if there are any real errors or issues).
- one way to control LibUSB verbosity is using environmental variables like <code>LIBUSB_DEBUG=0 LimeSuiteGUI</code>.
Firmware / USB
USB reset.
- This is a FreeBSD related issue. See post on the freebsd-usb mailinglist: https://lists.freebsd.org/pipermail/freebsd-usb/2020-July/016715.html and its follow-ups.
- [TODO] analyze LibUSB reset problem that prevents LimeSDR working on FreeBSD.
- [TODO] enabling non-root FreeBSD users to execute a reset or removing the call from the driver, we’re still debating on how or if the first can be achieved).
Firmware / RADIO
LimeSDR-Mini Hardware Self-Test fail with LimeQuickTest.
- [TODO] problem won't fix: changes to testing application not welcome (see https://github.com/myriadrf/LimeSuite/issues/339).
- [TODO] cause found: tests need to be performed with antennas disconnected (both RX and TX port empty) and device should be cold (board temperature over 40C will fail <code>RF Loopback Test</code>).
- [TODO] report issue on upstream github, done: https://github.com/myriadrf/LimeSuite/issues/339
- [TODO] some tests fail, depends on hardware and firmware relese. verify. confirmed with @cederom device on FreeBSD.
MCU error 3 / SXR tune failed.
- Issue seems to be reproducible with a [test program](https://sapphire.magnetkern.de/paste_1d1b4528287690e1e2dc1200acb41427/limetest_2020-09-03_0731Z.c). Under FreeBSD, ensure that libLMS7Support.so of Lime Suite has been installed in
/usr/local/lib/SoapySDR/modules0.7and compile with: <code>cc -Wall -o limetest-mcu-error -I /usr/local/include limetest_2020-09-03_0731Z.c -L /usr/local/lib -l SoapySDR</code>. Further notes on that issue can be found in the thread [MCU error 3 (SXR tune failed) on LimeSDR USB](https://discourse.myriadrf.org/t/mcu-error-3-sxr-tune-failed-on-limesdr-usb/5303). - [TODO] problem fixed. upstream / firmware updated.
- [TODO] cause found.
- [DONE] report issue on upstream, done: https://github.com/myriadrf/LimeSuite/issues/340 and https://github.com/myriadrf/LimeSDR-Mini/issues/2.
