Hi thanhhaipif96,
Your driver is not compatible with kernel/Image you flashed. Also, your driver does not have functionality to use interrupts based on GPIO. That’s why it says failed to acquire irq .
Why your prints is not visible because your driver is not updated under /lib/modules/…
I would recommend you to use my driver I have attached in this thread Jetson nano and mcp2515 can module
Compile this driver and flash the compiled Image first. Then copy this compiled .ko in /lib/modules/… after flashing, it should work.
Thanks,
Shubhi
