when I use integer number on terminal, compiler back "ld" (hex = 108 100).

I adapt the code to stm32. But when I use integer number for instance; 1+4, the code back "ld". Another example; first a=5 and then a, the code back "ld". How can I solve this. What is the source of this error? I try to find "ld" in the code but I can not find

I have no idea. I believe you need to add some debug/logging code to understand what is happening

I solved the problem ;

I changed BE_INTGER_TYPE 2 to 0.

It is not recommended to use 64-bit integers on STM32, as this can be very slow.
