SuperCAN Linux kernel module

This repository contains the Linux kernel driver code for SuperCAN, an open source USB to CAN-FD protocol.

NOTE: the code in this repository requires sources from the SuperCAN repository. It will not build if cloned by itself.

The main branch of this repository aims to stay compatible with the mainline Linux kernel. Branches for older kernels exist and are somewhat maintained.

Building the kernel module

DKMS setup

Install dkms if you haven't already, for instance

sudo apt-get install dkms

Checkout the branch matching your kernel version

You may need to checkout the proper branch to build the driver module.

The command uname -r will tell you what kernel version is currently running. The output will be something like 5.10.0-28-generic which would indicate kernel version 5.10.

Checkout the branch matching your kernel version, e.g. git checkout pre-v5.11. To get a list of the available branches, run git branch -a.

Setup the kernel module sources

<path to supercan>/Linux/dkms-init.sh

Add, build & install the kernel module

sudo dkms add <path to supercan>/Linux/supercan_usb-<version>
sudo dkms build supercan_usb/<version>
sudo dkms install supercan_usb/<version>

Uninstall and remove the kernel module

sudo dkms uninstall supercan_usb/<version>
sudo dkms remove supercan_usb/<version> --all

Build error supercan driver for 5.13.0-35 kernel

Supercan Branch: master
Submodule supercan-linux: pre-v5.13
OS: Ubuntu 21.10 / 5.13.0-35-generic

skb.c

void can_free_echo_skb(struct net_device *dev, unsigned int idx, unsigned int *frame_len_ptr)

Call from supercan_usb.c Line 402

I think "frame_len_ptr" is missing

for (i = 0; i < net_priv->can.echo_skb_max; ++i) {
    can_free_echo_skb(netdev, i);
    usb_priv->tx_echo_skb_available_ptr[i] = i;
}

I use the command from README:

make V=1 KERNELRELEASE=$(uname -r) -C /lib/modules/$(uname -r)/build M=$PWD

Log:
