@roberts_lando In the next release axon-kernel we include more modules (at least 1wire devices)

If there are some missing modules, you need to compile it.
On Axon (or generaly any arm64 platform) do:

apt install build-essential git 
git clone https://git.unipi.technology/UniPi/axon-linux.git
make unipi-axon_defconfig

Now you can change kernel configuration to desired state

make menuconfig

Compile new modules

make modules

You can compile on amd64 platform using CROSS_COMPILE

make unipi-axon_defconfig CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64
make menuconfig CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64
make modules CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64

@boy-lenssen Yeah, that's something we are working on to protect bricking the units during the FW upgrade process. If the RUN led is dead, send it to us so we can reflash the FW.

Using Owfs with kernel modules ds2482 doesn't work well.
It requires to disable ds2482 in devicetree.
Insert this patch

fdt set /soc/i2c@01c2ac00/w1master@18 status "disabled"

into file /boot/boot.cmd, call

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

and reboot.
If you have our new kernel, there is not file /boot/boot.cmd
In this case copy attached file attached file 30-disable-1wmaster.conf to directory /etc/bootcmd.d/src
and call

  cd /etc/bootcmd.d; make force; reboot

The files has been moved into a new repostirory: https://repo.unipi.technology/debian/ The FW tool for extension can be found here https://kb.unipi.technology/files:software:tools:00-start#extension_firmware_update_tool

Can you provide screenshot where we could see the configuration of the PI controller with all the parameters?

Added serial port map IDs https://kb.unipi.technology/en:sw:01-mervis:serial-port-numbers-hidden

The issue was by the incorrect comm speed with the modem. I modified the guide provided by @roberts_lando to use the proper baudrate of 9600 instead of 115200.

Hello,

you have to create your own library. In general it is best to create an empty project just for your own libraries. Then just create a new librry project and your FB within it. By compiling the project a .slb file will be created in the library_project_name folder within your project. This file should be copied to the C:/Program files/Mervix (xxx)/Library

@stephane-clavel Could you paste your evok confiruration and the picture of at least on of the xS? Is the cable done right (A -- A; B -- B)?
