Which JSON library is preferable for STM32F769 DISCO board?

[PDe N.1]

Hello,

I'm working on a project on STM32F769 DISCO Board in which I need to read and parse data from a .json file (3kb).

I tried using Nlohmann JSON.hpp library for data reading and parsing and, even if I do not have compilation problems (except for a certain number of infos), when I debug the program on the board, it seems that it is not able to read data from file. It is not clear if it is a memory problem or a problem with the library.

With the same library I managed to read and parse the same file correctly on a pc.

Any one has had a similar experience?

Can someone suggest a json library positively tested on a stm32 board (better if on a STM32F769 one).

Thanks

Have a nice day.
