IMXRT1062 CANFD not working with CANFD-USB

[jim_verheijde]

Hi everyone,

I have been trying to get CANFD on the IMXRT1062 to work with the CANFD-USB converter. However, this does not seem to work correctly. On my PC I get TX form errors as you can see below:

I am using the default settings from the following example project in the SDK:

SDK_2.8.6_EVK-MIMXRT1060\boards\evkmimxrt1060\driver_examples\canfd\interrupt_transfer

This uses a 20MHz CAN clock with an arbitration rate of 1Mbps and datarate of 2Mbps. I also made sure to select these speeds for the CANFD-USB converter.

This is the CANFD-USB converter I'm using:

Is anyone else having this issue? Thanks in advance!

It turns out I was using the wrong pins, after configuring the output pins of the CAN3 controller everything worked fine!

Hello jim_verheijde,

I’m not familiar with this CANFD-USB. Hopefully someone in the communities may provide their experience with it.

Have you tested this example using another board? (To rule out any other issue)

Hi Gustavo,

Yes I tried with two different imxrt1062 devkits and also two CANFD-USB converters (from the original post). So it is not a hardware defect.
