Documentation for fsl_flexcan driver in MQX 4.1?

Documentation for the kflexcan driver appears in \Freescale_MQX_4_1\doc\mqx\MQX_IO_User_Guide.pdf (Chapter 17 FlexCAN Driver)

Is there any similar documentation that exists anywhere for the new fsl_flexcan files in MQX 4.1?

I am specifically interested in learning about all of the different ID masking and filtering options for the FIFO queues.

Has there been any update to documentation for this?  I am using a K60FN device and was confused if the fsl_flexcan supports this in MQX 4.1.1 and what attributes should be modified.  I assume only the timings for my my specific implementation are unique.  Any other gotchas?

Hi Lisa:

The new FlexCAN driver was restructured from the old one. In release MQX 4.1, we added new layer HAL driver for FlexCAN. The new FlexCAN LDD driver can access registers through HAL driver only. Now the driver is ready to use in K70F120 and K60N512. Unfortunately I have not released document about this, I will update you when I have.



Have a great day,
Daniel

Hi Daniel,

Has there been any update on this? I'm starting fresh with Freescale and wanted to use the latest iteration of the driver from the start.

Thanks,

Larry
