Calibration Failure, Status =7

[hatefdm]

Hi
I'm facing Calibration Failure, Status =7 when running test_loragw_cal with the following result, so the concentrator does not start.

Library version information: Version: 5.0.1;

Radio B frequency: 868.500000 MHz

End of radio calibration test

I've run util_spi_stress successfully for multiple hours. We have ordered the bare PCB and assembled the board. Any ideas what the problem can be?

You might want to double-check the connection between SX1257 and SX1301/1308
Moreover, make sure that the 32Mhz TCXO clock is running, and the power is stable (Note: util_spi_stress doesn't really power-up the power-hungry stuff )
