--Apple-Mail=_A07ABCCD-0DD3-4073-B53C-1D1980208C8E Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii 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?
