Expected behaviour
RaspberryPi4 boots on and connects to network.
Actual behaviour
Robot suddenly stopped working.
The LCD screen on the turtlebot does not turn on; RaspberryPi4 computer does not seem to boot (when connecting via microHDMI, all I can see is a rainbow screen on both HDMI outputs); only a steady red light is on the raspberrypi board. Neither WIFI or ethernet devices are accessible (the default eth0 ip, which is specified correctly in the netplan config, is not reachable. So is the wifi ip, which is also configured correctly).
The Create3 base, instead, seems to correctly connect to the same WIFI network as before.
I wonder what would be the issue or how to debug it.

That does sound like either the RPi4 has died or the SD card got corrupted somehow. Did this occur while the robot was running or when you tried powering it on?
Thank you. It was indeed the SD card that got corrupted, re-flashing fixed the issue. The trouble is that the SD card got corrupted after a normal shutdown.
Currently the RPI just has its power disconnected when the Create 3 powers off. In most cases its ok, but sometimes this can cause data corruption. iRobot has this issue for implementing a delay to the power off service. Once that is implemented, we can call the RobotPower service with a delay, then safely shut off the RPi before power is cut.
Please provide the following information:
