Pins_DRV_Init(NUM_OF_CONFIGURED_PINS, g_pin_mux_InitConfigArr);

Hi,

It seems that the clock for the FlexCAN instance was not enabled from Clock Manager.

To enable the clock:

- Open Clock Manager PEx component

- Go to PCC tab and tick on Enable checkbox for the desired CAN instance

- Generate Processor Expert Code and Build the project

Best regards,

Rares

Hi raresvasile,

I am trying to do the same (porting FreeRTOS alongwith Flexcan) but ProcessorExpert generator is giving some error

ERROR: Unexpected status of script: Beans\flexcan\Items\S32_SDK_C55\flexcan.chg, please contact Freescale
ERROR: Unexpected status of script: Drivers\Common\EBGNSupport\TimingLib.prg, please contact Freescale support.
Generator: ERROR: There are errors in the project, please review components configuration. It is not possible to generate

I am using s32ds v1.2 with latest update for EAR 0.8.1,

Can you help me how to resolve this issue.
