Flexcan porting to FreeRTOS

jay_zhang — Tue, 07 Aug 2018 04:13:17 GMT

Dear NXP dev team,

I met a issue with CAN transmission sample, my goal is port the can send/recv function to my project, my project is based on FreeRTOS, but after porting the code from flexcan_encrypted sample, find the MCU reset forever.

I have attached the project source code.

I after debuging the issue, I find the below code maybe the root cause to produce the issue,

After remove the FLEXCAN_DRV_Init code, the MCU can run normally.

But the flexcan_encrypted sample run successfully on my board.

Please help me to resolve my issue.

Thanks

Jay

hi, zhang jie:

I suggest you put the prvSetupHardware() in a task, because the sdk use some os api(osif).

Hi Fu Zeng,

Thanks for your reply.

The issue is fixed.

In the FLEXCAN_DRV_Init function, I find if you use the RTOS, it will create 32 sema:

But the default RTOS environment only config 8192 bytes heap size, after increase the size can fix this issue

Thanks

Jay
