Hi All,

I need to create a library for a project using the STM32F4. I have tried using both CoIDE and GCC command line tools. No luck at all, I ended up in Default_Handler() when the library function was called. Creating a library using command line tools for Cygwin or Linux is no problem.

I guess it's just a stupid mistake on my behalf. Any ideas?

That is often a common dumping point for things like HardFault, why would it fault, the number one reason for libraries is that you have linked 32-bit ARM code, not 16-bit Thumb code.

If you debug you code you might notice a BLX to the subroutine. Look also at the .MAP file.

Make sure you build your libraries objects with the right cpu/architecture settings.

Thank you for your quick reply.

It was just a stupid mistake by me. I had forgotten to point the linker to my latest attempt to create the library.
