Hi, thanks for your comments. Naturally the object file has been developed and compiled with M2M Studio & OpenAT.
Inspecting the object file with hex editor shows it to be compiled to OS 6.35.0 whereas we use 6.31.0.
Even if it has been built with DS, you have also to make sure that it has been compiled with the same toolchain that you’re using for linking your app. Toolchains are mainly incompatible (i.e. most of time objects built by a first one can’t be linked by another one); the only exception is ARM RVDS 4.0 and ARM EABI GCC toolchains, which can interwork properly.
Another tip: rather than modifying the linker command line, you should use the Miscellaneous > Other Objects list option of the linker to add external objects to your application: it will put it in the right order on the command line (since the linker cares of the objects order on the command line).
