FreeRTOS + TMS570 + DCAN module

Posted by pr0metha on May 4, 2013

I'm working on a project that involves FreeRTOS and a TMS570LS31x HDK board. At the moment, I'm using the FreeRTOS Demo for CC5/TMS570 USB stick. I've added some drivers using HalCoGen, and everything has worked until I added HalCoGen drivers for the DCAN module. I am able to send out CAN messages, but regardless of my settings I'm only transmitting empty messages ( Identifier = 0x00, DLC = 0, and all data fields are empty).

I figure that maybe the CAN RAM isn't initialized properly. Do anyone know if this is done by the Demo that I use, or do i need to add it myself? I found an assembly routine for this in the source code, but I'm not sure if it's really running or if I have to change it in some way.

Has anyone been able to get the DCAN module working together with FreeRTOS?

Does the DCAN module work without FreeRTOS. Try using it before you call vTaskStartScheduler() and if it still does not work then your problem is not FreeRTOS related.
