Description

MCU freezes on init radio.

I have DYI hardware + E22 400M30S module (SX1268)
after flash firmware MCU work well, but when I setting region EU433 - MCU going to infinite loop with freeze and reboot by watchdog

I changed couple modules - i have always same trouble.

Does this module and MCU work with firmware before 2.1.0?
There is an open issue (#2208) with the same module, but it seems to fail at a different point now.

firmware 2.0.23 infinite loop with reboot see this log:

[caveman99]

this kind of crash is often an incorrect pin assignment/setup. It's waiting for a state change that never happens, or double-uses I/O lines and tangles them up.

[MasterSPB]

Hmm,
I checked MCU without connected modem on firmware 2.1.3 - and have same issue like in my first message

....
INFO | ??:??:?? 62 Slot time: 42 msec
INFO | ??:??:?? 62 Set radio: final power level=22

E (92100) task_wdt: CPU 1: IDLE

this mean current firmware have incorrect modem check

[caveman99]

please try 2.1.4 - there was a change regarding EU_433

[MasterSPB]

I did a lot of tests and think the issue with reboots is related to hardware (not good power for module)
Because reboots sometimes stop when TX power minimize or change power capacitor

[caveman99]

This was a bug in recent RadioLib - will be fixed in Firmware 2.1.7 or in current Master branch

[SCWhite]

HI @caveman99
I'm having same issue with firmware 2.1.11
using the "LLCC68" lora module still have some problem.
