sorry to report back that even with the external PSU we are still having lots of problems.
Flashing firmware went down to just a couple of times in a session, but has recently got a lot worse.
Just now we are getting this error from gnuradio (previously working)
e[1me[33m[WARNING] SoapyLMS7::setSampleRate(): not a power of two factor: TSP Rate = 15.36 MHZ, Requested rate = 10 MHze[0m
e[1me[31m[ERROR] setBandwidth(Rx, 0, 30 MHz) Failed - e[0m
Then when we try to run it again:
e[1me[33m[WARNING] Gateware version mismatch!
Expected gateware version 2, revision 12
But found version 0, revision 0
Follow the FW and FPGA upgrade instructions:
Or run update on the command line: LimeUtil --update
Then we can flash it again but the same problem persists. It seems to have got worse ;(
