I spent some hours..
1) flashed the octopus MCU with dfu-util
2) draft version of HAL and INI files done
3) wiring pi5 correctly to the octopus
4) pi5 is running remora flexi os
The error is from linux cnc when it loads my config: joint.5.scale pin doesnt exist. If I do a show pin with halcmd it shows a bunch of joints unit joint.4.

to make the NVME working on the original linuxcnc rpi image,
i need to add this options to /boot/broadcom/cmdline.txt:
the 2nd ethernet-port works out of the box (eth1)
i used this for the normal network and eth0 for the FPGA connection:

i build a new component to use the I2C port on the RPI4/5 for extra Digital-IO's and ADC's
can be used standalone, no rio needed: github.com/multigcs/riocore/blob/dev/rio...ins/rpii2c/rpii2c.py

First of all I really want to say thanks for all the work you've put into your projects, you really deserve a couple of beers, if that's your poison
or a least a good coffee, damn mate whatever you like to drink. Honestly thanks.
Haven't had a chance to use it or try it out but it looks great. One of the things that has been missing for the RPi IMHO, would be great to see in the mainline Linuxcnc tree.
Would be great if you could add this to the RPi "mega thread" and I'll add a link in the index.
Now a request for an extra feature, any chance for ADC support. Would be great for things that a user wants or needs an analogue input.
