Interrupt CAN with k10 cortex M4F and freertos v8.2.2

achourislaheddi — Tue, 12 Jan 2016 14:26:02 GMT

Hello,

I am developing a program on K10 Cortex-M4F that uses the CAN bus interrupt, but I do not get any CAN hardware interruption with FreeRTOS, However, the messages circulating on the bus.
For information, I used processor expert and authorize NMI interrupt and interrupt service to the CAN bus.
I wanted to know if FreeRTOS can block material interruptions? what to do to allow the hardware interrupt with FreeRTOS?

Thank you

Hi Slah，

Actually there's no difference to create a interrupt function no matter integrate with the FreeRTOS or just baremetal.

I'd highly recommend that you should check the interrupt function should be assigned to the vector table correctly.
Have a great day,

First be sure the problem is related to FreeRTOS by trying to use the interrupt in a dummy app that doesn't use FreeRTOS.

Do you find the interrupt works after the FreeRTOS scheduler has been started, but not before? if so, see number 3 on the following FAQ page: http://www.freertos.org/FAQHelp.html
