Hi,
I'm trying to link the static esb library (esb_gcc.a) with the mbed toolchain. Everthing seems fine until the last stage of the linking phase where my actual functions aren't resolved. The static library is found by gcc and I can't find out what's wrong. Is there any magic flags that I've missed or any other things?
Below is the output:
