Hi, I have started to work on MCP25625, which is similar to your MCP2515. Were you able to get it to work for you with nios?

Thanks,

Hello,

I'm currently working on interfacing the MCP2515 CAN controller with a Nios II processor via SPI. While I can observe SPI transactions on a logic analyzer, I'm not receiving any responses from the MCP2515.​

Has anyone successfully interfaced the MCP2515 with a Nios II processor? If so, could you share insights or code snippets that might help identify what might be going wrong in my setup?​

Any guidance or suggestions would be greatly appreciated.

Thank you!
