@terranx , You are right, I don't know where I got the idea that the device would have to appear in the /dev directory, it helped me to see the command to show the CAN connection, I needed to have it working to start learning, thank you very much.

@terranx 'ls /dev' command returns:

@terranx, excuse my ignorance, but how do you make a custom overlay? 'dmesg | grep can' command returns the following error: rockchip_canfd fea60000.can can0: rockchip_canfd_get_berr_counter RX_ERR_CNT=0x00000000, TX_ERR_CNT=0x00000000

@Biohazard777, I have not had problems in the configuration of I2C and SPI in the last version of Armbian, but CAN still does not work. If someone could try enabling it and reviewing the /dev/ directory, it would be very useful, regards.
