ARTX: DATA ABORT WHEN USING SWI FUNCTIONS
Information in this article applies to:
- CARM Version 2
- ARTX-ARM All Versions
QUESTION
I have problems getting my ARTX application to work. It appears that ARTX crashes (with Data Abort) when I use __swi functions. What can be the reason for that?
ANSWER
ARTX uses its own SWI Handler which is automatically linked from the library. If you include another SWI handler (like that found in the SWI_VEC.S file) in your project, ARTX could fail. Remove any user-created SWI handler from your project to resolve the Data Abort.
Note that software interrupts 0-7 are used by ARTX-ARM and cannot be used in your application.
MORE INFORMATION
- Refer to __swi: Software Interrupt in the CARM User's Guide.
