The new Cerbo GX MKII loses the connection via VE.CAN2.
It seems to be a hardware problem. When the CPU temperature exceeds 50°C, it starts to lose communication with the CAN chip.
The Cerbo keeps trying to establish the connection and the error counter and retry counter are counting up.
This increases the CPU load and the CPU temperature continues to rise. As the temperature rises, the number of erroneous messages also increases until the Cerbo finally crashes.
After the restart, the VE.CAN devices are no longer visible. Only when the temperature falls below 54°C again. A connection can be established sporadically.
I have opened an RMA to get a solution.
Up to now I have been using a PCAN interface which can be integrated as a Plug’n Play. This allows the CAN connection to be maintained even at high temperatures.
I hope that Victron has designed the newer models differently. Alternatively, you would have to work with alternative CAN adapters or switch to the Raspberry Pi.
If my Cerbo is not replaced, I will open it up and find out about the CAN chip.
I see difficulties in solving this problem with new firmware.
