QCA9533 ver 2 rev 0 - reboots (CPE210, CF-E110N, ...)

For Developers
1

I have two types outdoor CPEs, TP-LINK CPE210 V2 and COMFAST CF-E110N V2.
Both (more or less) work only on firmware 19.07.10, but reboot by themselves every 1-2 days.

Version 22.03.6, 23.05.2 (I'm afraid that 21.02 too, but it needs to specify) makes those hardware useless, they reboot every 2-3 minutes, sometimes reboot commits right after boot.

I don't have any opportunity to get to serial console for glancing what's going on.

I also noticed that that happens when the environment temperature is lower than +10 degrees of celsius plus the hardware has heavy traffic. And sudden reboot never happens during firmware process (otherwise I think I've had a brick a long time ago).

Might be someone encountered?

I wouldn't consider this 'working', typically the uptimes of OpenWrt devices is measured in months+ (only interrupted by upgrades or major configuration changes, so caused by the user, not rebooting on their own).

This suggests hardware failure (and a thermal component, which is quite common).

I have three cpe210 and one cf-e110n they all have the same symptoms.
These models are quite cheap and popular, am I really alone?

This is uptime by week:
