Hello, 

ELF/DWARF Error: Unsupported .debug_info format version:4

 This indicates an issue with debug settings that have been fixed after SDK v13.0. In your Makefile, please find the following line

CFLAGS +=  -Wall -Werror -Os -g3

And remove -g3. This should solve the issue. 

Kind regards,
Øyvind
