        I don't understand. I have tried to comment out some lines. Sometimes
firmware runs as expected, sometimes, it continuously reboots.

        When I comment out some lines or add some debug trace, firmware desn't
crash at the same place. I have deleted some piece of code to only
initialize my board and to try to access to SX1262...

        Nope, unfortunately. I have done tests with in-board uninterruptible
power supply and with an external 150W power supply.

        Please note that simavr shows exactly the same result :

        Real board reboots (or stalls) when simavr enters in gdb.
