I have a problem with portsdown software and limesdr mini
Hardware v1.2 Firmware v6, Gate ware v1.30
First 5 say passed
TX2 LNA W TEST FAIL
RF LOOPBACK TEST FAILED
BOARD TEST FAILED
Further investigation require
Note that custom FPGA ALWAYS FAILS
What have I got wrong it was working
The test is very sensitive, and will not pass if the LimeSDR Mini has warmed up (!) or has anything connected to the SMA ports. My LimeSDRs (I have 3) sometimes pass and sometimes fail.
I tend to ignore the test - if it transmits OK, it's working. Just try it!
Suggest that you go back to a known baseline.
1. Reload the basic Lime Firmware: Menu3, Lime Config, Update to FW 1.30.
2. On Menu 1, select Ouput to, Lime Mini. Make sure that you have S2QPSK modulation, Encoder H264, Format 4:3, Source PiSCreen, Freq as required, Sym Rate 333, FEC 9/10, Lime Gain 88 (or more).
3. Then select transmit. What power can you measure (or not measure)? Remember that it takes about 15 seconds to transmit.
Let us know how it goes.
