How is CRYPTOCELL_IRQHandler linked in a project using CC310? I have built ble_app_interactive and it links to the library routine. However I need to develop my own application and so I tried to create a new project starting from ble_app_interactive by moving files to a different subdirectory structure. I then readded all the project files and amended the include search paths. The project compiles without error and runs as far as initialising the RNG. The program then hangs in a tight loop at the default CRYPTOCELL_IRQHandler.
