Fatal Error on Configuring Pinmux for MCP251x CAN Controller

Hello!

I’m attempting to configure my Jetson Nano to interface with the MCP2515 but I am unable to apply the preset configuration. This is the error I get.

I’ve tried re-flashing the SD card but the error persists.

Is there anything I’m doing wrong? Are there any workarounds?

Please follow steps mentioned in doc for MCP to configure properly:

Hello @kayccc, I did follow the guide. This error is only present on Jetpack 4.6. I downgraded to Jetpack 4.5.1 which doesn’t seem to have this specific issue. I still cannot transmit data through the MCP module even after adjusting the clock speed. I am stuck along with everyone else following this thread: Jetson nano and mcp2515 can module
