SPC584B - Issues with CAN RX

SKara.7 · ‎2022-01-19

Hi,

When I use the low level drivers that comes with SPC5 Studio, I am facing issues with CAN reception.

The Rx buffer only updates with the highest priority message. All the messages below that are ignored.

I tried with FIFO and Dedicated Buffer settings, but both have the same problem.

Please can you advise on how to fix it?

Best regards,

Hello ,

could you send us your configuration.xml and your pin settings ?

I recommend to check the status of your register with your debugger.

Hi Erwan,

Please find attached the configuration.xml file.

I hope you will be able to see the pin settings as well from configuration.xml

What I see is, the other Rx messages are in 'wait' state. Rx buffer always captures only the highest priority message. The rest of the messages are in 'wait' state when I debug the return value of can_lld_receive() function.

Best regards,
