SocketCAN Driver

[Augusto Fraga Giachero]

Hello!


I recently started a project that uses the CAN serial protocol using
microcontrollers. I've got an IXXAT CAN-to-USB Compact (V1.0) adapter to
help debugging the CAN bus. The manufacturer of this adapter provides
the kernel driver and and userspace  libraries for Linux, but it uses a
custom API (ECI) instead of SocketCAN (and I really need to use
SocketCAN). The manufacturer also provides a SocketCAN driver but only
for the CAN-to-USB Compact (V2.0), so it doesn't with what I have.


I'm thinking in modifying the the SocketCAN driver to support the V1.0
adapter, but I don't have any experience in kernel driver development.
I've a solid C knowledge and a lot of experience in firmware development
for microcontrollers. Can someone show me where to find relevant
information regarding SocketCAN, USB drivers development? I don't know
if this challenge is above my skills.


I've attached both drivers and a patch for the usb-to-can_v2_socketcan
that substitutes the "netdev->trans_start =" deference to
"netif_trans_update(netdev);", so you can compile for kernels newer than
4.4.



Thanks!
