Last update of LinuxCNC Raspberry Pi4 USB does not work

Hi

Today test with brand new pi 400 using :
www.linuxcnc.org/temp/image_2021-01-20-linuxcnc-pi4-3G.zip

No wifi detected.

I use: github.com/LinuxCNC/pi-gen

But it relies on all the packages being available on a repository, and just assembles an SD image to a repository.

git clone it, edit the "stage" files, and then "sudo ./build.sh". A base and light image will appear in the "deploy" directory some considerable time later.

Yes, Pi400 remains a problem. (I have one)

But the Pi400 _probably_ isn't a good CNC controller candidate?

The LinuxCNC docs now point at a (renamed) version of the 3G limited image, with warnings that it is known to not work on all variants.

andypugh, according to my latest test (see my previous post), the www.linuxcnc.org/temp/image_2021-01-20-linuxcnc-pi4-3G.zip does work on Pi 8GB. Wlan and USB are ok.

There might be a fix in the kernel discussed here:

There is a downloadable kernel image deb here:

(I have not tried it)
