RPI4/8GB i2c not working?

[Mark Murray]

Hi Folks,

I have a RPi4b/8GB with USB SSD HD, and its working very well. I started with the FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20210304-483c6da3a20-257149.img snapshot, and replaced the /boot/msdos/* files with those supplied in the rpi-firmware-1.20210303.g20210303 port.

It's working well, and now that I've built a new kernel with all the non-RPi goodies removed as well as commenting the other -CURRENT debugging gubbins out, its pretty quick!

I2C isn't working though.

All I get in response to "# 12c -s" is:

# i2c -s
Hardware may not support START/STOP scanning; trying less-reliable read method.
Scanning I2C devices on /dev/iic0: <none found>

... with a few minutes of delay between the 2 lines of output.

Maybe the IIC device needs to be changed for the 8GB RPi4? Or something?
