tfm_ns_interface.c is intended to be overriden by clients to support different targets. We copy this file from upstream into the mbed-os platform library. We also have a specific "strong" overridden version for the NU_M2354 target, which is located in its target library. Previously the implementations in the platform library were decorated with __attribute__(weak), and we provided a strong definition for the NU_M2354 target. This worked fine because of weak linking, the linker will pick the first "strong" definition and use that, avoiding any ODR violations. However, upstream have removed __attribute__(weak) from the function definitions, which caused multiply defined symbol errors when trying to build the NU_M2354 target. To work around the above issue, we remove the common definition in the platform library; instead we copy the file to the Musca B1 and Musca S1 target libaries. This means the appropriate tfm_ns_interface.c is only included in the build when compiling for the specific target which uses it. |
