The goal is to run this configuration at 1MBit/sec, with a bus utilization of a little over 50%. In my testing, I have found that I consistently get CAN bus errors with this configuration, usually Stuff errors and Form errors. If I remove a device from the bus, the errors go away If I decrease the bus utilization, the errors go away
Dear Community I get a "Bus error" when using memcpy to copy 10 bytes from a local array to the On-chip memory (see code below): int memfd Seite 2 von 8 CAN-Troubleshooting Guide Rev. 1.1 N O T E The information in this document has been carefully checked and is believed to be entirely reliable. esd makes no warranty of any kind with regard to the material in this document, and assumes no Voltage and resistance on the Can C bus are normal when problem not occurring, but when problem happens the voltage on the high and low sides of the Can bus go to 2.5 volts each with no stagger. Unfortunately once you turn the ignition off then back on the problem corrects itself making diagnosis very difficult.

Changes in the chapters The changes in the document listed below affect changes in the hardware as well as changes in the description of facts. Chapter Changes as compared to previous version; Additional notes on CAN-GND. In the body of function sum() the summation variable x is not initialized. This code will compile and execute on almost any C platform. The value returned by sum() will be equal to the sum of the first n values stored in A plus whatever value happens to be stored in the memory allocated for variable x when sum() is called.
