MCU 'EBBCan' shutdown: Timer too close This often indicates the host computer is overloaded

Generally see: Timer too close

From the log you attached and the fact that you have a rising bytes_invalid counter, some additional potential reasons are:

  • Old, defective firmware on the CAN adapter
  • Old, defective kernel on the Linux SBC. It should be a kernel version >= v6.6, as previous versions may suffer from a serious CAN bug.
  • Your buffer size is much too high and exceeds the recommended value of 128.
