ESP32 problems Object pool

[Jakob1934]

I'm relative new to the topic and tried to implement the esp32 example. Everything worked fine, code was build and loaded. But every time I plug the esp with can hardware in the tractor something fails. I have tried with the seeder and other examples but same error every time. I also tried the simulator, but same problem with the esp.
The object pool gets loaded into the terminals but it seems parsing the pool is the problem.
I have tried with an older MF model tractor and a new Fendt One and I have similar problems. The Fendt shows "Error in object pool" and resets, the MF just resets the connection.
Originaly I wanted to build an integration for an old seeder.
Has anyone had similar problems? Do you recommend other hardware?
I attached some logs.
How do you create object pool files, can you recommend any free software (haven't found anything yet)? And how do you integrate the pool then into your software (buttons and functions.... )? Are there tutorials for this combined process?
Thanks for your answers.
