Describe your issue:


recently, yesterday, I have installed an EBB42 by Can, until now I had it by USB, but since it had disconnections, I have changed it to CAN.

I thought that the disconnection problems were over, but in the first impression after the installation shortly after starting, in the first layer I received this message and the impression has stopped.

MCU ‘EBBCan’ shutdown: Timer too close
This often indicates the host computer is overloaded. Check
for other processes consuming excessive CPU time, high swap
usage, disk errors, overheating, unstable voltage, or
similar system problems on the host computer.
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

Why can this be?

It’s an Rpi4, so I don’t think this is overloaded
The temperature of Rpi is 49º


at the end of log… can be read some messages like this

Got error -1 in can write: (105)No buffer space available
