I have a device here which has only a CAN interface to the outside world. I am currently thinking about implementing a "serial" driver using the CAN controller.
Is there any chance to get this accepted in the public u-boot tree?
someone just posted a port of the Linux CAN framework. if your driver used that to implement a serial layer, i dont see why it wouldnt be accepted.
Well, that means that I have to implement a full functional CAN driver and then additionally add a serial driver using the (completely new) CAN framework. My idea was that I just add a serial_ccan.c to drivers/serial.
you would rather write a driver that is specific to one CAN hardware ? writing it to a common framework would allow every one with a CAN driver to use it ...
There are many simple USB CAN devices which are operated through the tty interface. See
