If you mean the dev containers I use: you can test whether it compiles and build firmware. I never got the card to talk to the container, because UDP packets get lost. One way to solve that is to use a cheap USB to Ethernet adapter and assign that to the container. My solution is just to use an old NUC, so no virtual OS for me anymore.

  What is the reason for this? The first time you brush the firmware, you can connect the board, and the linuxcnc can also display it. After the linuxcnc is closed, the connection will be like this

Have you tried naming a hal file in English?

The error you get is that the checksum of the board is different from the checksum of the config-file. Could you please verify:
  • you did not change the JSON-file after compiling the firmware?
    As even changing the name or changing a line ending will lead to different CRC checksum, changing names requires recompilation. Maybe something went wrong while copying the file. You can check the check-sum your self with an online CRC calculator. When compiling the driver it will also show you the calculated CRC which is stored on the board.
  • if JSON unchanged, do you use other then UTF-8 characters?
    I didn't test it with extended character sets (i.e. UTF-16 etc.). These files might mess things up due to a BOM being present, which might be not read with Python, but are picked up by the driver.
Status update:
I expect this week to finish a full refactoring of the driver. This new driver allows for:
  • easily adding driver for new components. They are now stored in the folder ./driver/modules and are automatically picked up when compiling the driver. All of the modules in this folder have a fixed format, so easier to read and develop your own. 
  • the firmware can have any number of modules. If you only need GPIO, you only have to add GPIO. This makes the compilation of the firmware more efficient. Also this allows number of modules easily to be expanded.
  • preparation is done for loading the config from the board instead from the JSON. If problems with loading from a config persist, this might be an option to make things easier (although you will lose the possibility to rename the pins, but you have the alias commands in HAL anyways)
The structure of the had to be slightly modified to support this behavior, see below for an example.
