Radxa rock 4 can bus

Hi,

I want to use a mcp2515 can controller over spi1 or 2.

 

I read about internal flash is blocking the spi1.
 

Can I use another Chipselect pin to use the spi1 with GPIO?

 

Can you please give some advice where to start my research about overlays?

 

What else do I need to activate? (core moduls, driver…)
