Summarize the issue concisely. For example: "CAN RX Error and Interrupt Issue on RH850-F1KM (R7F701686)

"I have a project on the RH850-F1KM (R7F701686) microcontroller with CAN protocol, FreeRTOS. The project was working previously but now shows a CAN RX error, and CAN interrupts are not functioning as expected. Has anyone experienced similar issues or know what could cause this behavior?"

CAN RX Error Specifics:

  • "What are potential causes of CAN RX errors on the RH850-F1KM when the CAN configuration hasn't changed? Are there any specific registers or settings I should check?"

"My CAN interrupts on the RH850-F1KM have stopped working. What could cause previously working interrupts to fail without any changes to the interrupt configuration? Could this be related to FreeRTOS or other peripheral interactions?

Debugging FreeRTOS and CAN Together:

  • "Are there known issues with FreeRTOS that can interfere with CAN communication or interrupts on the RH850 series? If so, what are best practices to debug such issues?"

"Could recent updates to the Renesas toolchain or FreeRTOS library affect CAN or interrupt behavior on the RH850-F1KM? Has anyone experienced compatibility issues after such updates?"

"What specific debugging steps or diagnostics would you recommend for resolving CAN RX errors and interrupt issues on the RH850-F1KM microcontroller?"
