ESP32 DevKit - Frozen code

[Jurkylius]

Hello,
I have one big problem. I have working code but if I want doing anything else as writing or reading json files ESP give me Memory error.
I try using minimal code but for all sensors and sending data via uart have using many memory.
I think about frozen code because I need use many lists and cant using standart allocated buffers.
Have someone tutorial how create frozen code of micropython? My project is almoust done but if I save many data to file or reading data from sd card program will fall.

Many thanks for answers

The simplest way is to make your own board definition and compile MicroPython using that board definition. The TinyPico is a good example https://github.com/micropython/micropyt ... s/TINYPICO

Note that the board definition folder doesn't have to be inside the MicroPython repo.
