I've tried to reproduce this with my old 3.2 & hand soldered
3.3 dev module, with different vehicle modules and modem GPS
disabled.
Results:
- the vehicle module is irrelevant
- 3.2 (SIM5360E) runs without issues (had this running over night)
- 3.3 (SIM7600G) consistently crashes by the TWDT within a couple
of minutes after modem init
This is caused by the modem task hogging core 0 as soon as the PPP
connection is up:
I (87161) cellular: Identified cellular
modem: SIM7600/Experimental support for SIMCOM SIM7600
D (87161) cellular: Remove old 'auto' modem driver
I (87161) cellular: Set modem driver to 'SIM7600'
I (87161) cellular: State: Enter PoweredOn state

Anton:
I
woke from sleep thinking "interrupt storm."
Craig's observation makes me wonder... Does the gps system
produce interrupts which are not handled properly when gps is
turned off. Unhandled interrupts might get constantly repeated
causing the IDLE tasks to starve?
I think that may be the case. Maybe the NMEA MUX channel gets
continuous input from the 7600 when GPS is disabled?
Regards,
Michael

One more
data point; I turned GPS off on my dev module (v3.1 board with a
sim7600A running 3.3.001-285-g601f2a70-dirty) and it started
crashing.
Has anyone outside the US tried this?
