can-loopback not working?

[eiten]

Hi everyone,

I'm playing around remotely with a STM32F103. I'm trying to get the CAN loopback working. My DTS file and the can c file are attached. The problem is: I can't get the can loopback mode to work. I think this is because on the STM32, there is nothing connected to PA11, and this pin has to be high to init the can controller. Strange thing, I don't get any error.
Then, I tried the zephyr,can-loopback (see DTS). With the loopback-device, the outcome is the same! I don't receive anything:

Has anyone an idea?
Thanks, Edi
