Our setup contains a Tofu Board, a Raspberry Pi CM 4 and the RM502Q-AE modem via PCIe.
On initial startup everything works as expected: The interfaces (rmnetXX) show up as expected and we get an IP address (As shown in screenshot 2).
When we do a software reboot of the raspberry pi, suddenly the quectel-CM (Version 1.6.2) returns an error, as you can see in the screenshot 1.
The Device is detected correctly and the /dev/ttyUSBx interfaces are there and working as desired as well.
Can anyone help?
