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. Best regards, Michael Lauer.
