Problems sending FlexCAN frames with imx1062

Contributor I


I'm developing a project for a imxrt1062 using the IDE IAR embedded workbanch. I run EmbOS, and I use the fsl drivers provided by NXP. I have some problems writing my own driver for the CANbus. I'll attach both the fsl FlexCAN driver and mine.

What I'm trying to do is initialize a CAN object, create a frame, send it in a loop through the CANbus and receive it on my laptop using the program MiniMon V3. 

For some reason MiniMon receives all the messages but it gives me a form error for each frame. I cannot understand why I'm getting this error. 

Any suggestion is well accepted!

thank you for your help,


P.S. I'm a beginner, so if you see that I'm doing something strange please let me know, thanks.

Hi giacomo mazzola ,

  Do you test the official flexCAN example code in the RT1060 SDK? Just as the following SDK path code:


  Whether this code can works OK on your side?

  You can test it at first, then modify the code in the official SDK code to meet your own demand.

Please check it at first.

If you still have questions about it, please kindly let me know.

Have a great day,
