MCP2515 vs MCP2518FD zephyr compatibility

[babos]

I am using a development system that uses a Microchip MCP2515 chip which has the drivers included with Zephyr and everything works perfectly with 52840dk board.
Who can tell me if I can then use the same firmware with an MCP2518FD chip without modifying the source code? Or if not possible a suggestion.
Thank you

Hello Babos,

If I understand correctly, your question would ultimately be whether the Zephyr driver for MCP2515 is compatible with MCP2518D.

Unfortunately we cannot support with this question.
The driver is a part of the Zephyr project, and the devices are from Microchip. I must suggest you to contact them for support.

If you want to try it on your own, you can read the datasheets of the two devices and see if they share the same SPI Interface specs. If they are the exact same then maybe the driver for one will work for the other.

MCP2518FD | Microchip Technology

Sorry we cannot help any further.

Best regards,

Hieu

Babos, I would suggest you create a feature request ticket here. If you do not require CAN-FD, you may consider SJA1000 which also has Zephyr support.

It looks like there was a PR with a MCP25xxFD driver implementation, but the branch became stale and it appears there were unresolved issues.

very grateful for the reply
