My team and I have designed and developed
a new CAN(FD) adapter based on ESP32S3 and MCP2518fd
primarily aimed at ECU firmware reprogramming,
but eventually also for the use as OBD2-adapter,
CAN-logger, etc.
The next incarnation will also have a
USB interface and I’m planning the necessary
changes for its firmware.
I would like it to be compatible with SocketCAN
out of the box — optimally without writing a
Linux driver, but rather reusing an existing one.
Which of the mainline SocketCAN drivers would you recommend
basing my USB protocol on? From a quick glance,
I’m leaning towards GS-USB, since this already
supports different hardware families.
Yes. I would also recommend the gsusb driver and the CandleLight
firmware project on the other side:

... where currently the CAN FD support is in the testing phase IIRC.
Both the CAN(FD) adapter firmware and also the Linux kernel driver is
actively developed by Marc Kleine-Budde and others.
Best regards,
Oliver
