Thank you, ning, for replying. What I found was that /boot/armbianEnv.txt, after a clean install, already contained an overlay_prefix, which was different in value from what I found in the clean install, so I left that alone and just added the other two parameters. The devices became visible after the reboot. Thanks again for the quick reply. I am new at this and I appreciate the help of experts.

After a clean install of 22.11.1, I edit /boot/armbianEnv.txt to add: overlay_prefix=sun8i overlays=uart3 i2c0 spi-spidev param_spidev_spi_bus=0 and reboot. After the reboot I list the /dev files of interest and there is/are no "spi*" entries: pi@orangepipc:~$ ls /dev/i2c* /dev/spi* ls: cannot access '/dev/spi*': No such file or directory /dev/i2c-0 /dev/i2c-1 pi@orangepipc:~$ Not sure if it makes any difference but I only have power, HDMI, and RJ45 connected to the board at this time, and nothing connected to the GPIO pins. Below are the states of two files, one from which I got the BOARDFAMILY, and the other into which I placed that value as "overlay_prefix", and the "overlays" and "param_spidev_spi_bus" values. Any and all help appreciated.
