Porting guide

[alejoseb]

Hi,
I tested Berry on Tasmota and it is awesome.

I saw the example for STM32 with a makefile, but it is not working anymore.

How I can port the current version?

Particularly on the documentation (https://github.com/berry-lang/berry/wiki/Appendix-B#2-porting)
Can anybody elaborate a bit more please?
What is the meaning of "Use map_build tool to generate constant object code and then compile"

I would like to integrate directly berry in a ST Cube IDE project with gcc compiler.

Thanks

Hi, I suggest to not use BE_USE_PRECOMPILED_OBJECT when starting to port Berry, it makes things simpler.

The porting process is very straightforward, you need to adapt be_port.c (even here you can do the file part later), and everything else should just compile fine.

Did you try compiling the source?

Hi, thanks for your answer.
Yes I did it, but I used BE_USE_PRECOMPILED_OBJECT = 1 as default, otherwise code did not compile.
Besides that, I modified be_port.c as you suggested and I am able to interact with the Berry's REPL using a serial console connected to my STM32 microcontroller.
However, I am not sure why it is not printing numbers, it only prints strings. When I try to print a number I get ld. I am not sure if I am porting something incorrectly. You can see on the attached image that I am able to print the string variable a, but I cannot print the integer variable b. The same code works as expected on Linux though.
