CAN communication stopped during power cycle

[Aravind1]

MCU - S32k342  

SW32K3_RTD_4.4_2.0.0

During the Flex CAN init phase , the application got struck into the freeze mode due to the MCR[FRZACK] & MCR[NOTRDY] bit was not set & timeout occurs. This issue was observed with the CAN bus high load more than 50 percentage. The issue is not observed in the Normal CAN bus load. Please provide the response to avoid the issue in CAN bus high load.

Thanks,

A.Aravind.

Hi,

please specify functions called and line where code is stuck. Add MCR and ESR1 content as well.
After power on/reset module is disabled, there should not be issue to enter Freeze mode after module is enabled.

BR, Petr
