Semihosting causes crash when not running in the debugger...

Tunisia

Hi Charles,

It is quite normal that your program that uses semihostion cannot run without attached debugger.

What is semihosting?
Semihosting is a mechanism that enables code running on an ARM target to communicate and use the Input/Output facilities on a host computer that is running a debugger.


In fact, the _write routine of rdimon library generate software BKPT instructions handled by the debug agent (here openocd) .

Generally when we need to use semihosting for debugging and we need to have a release version for standalone running purpose we manage to create two different configrations :

  1. Release Configuration : in which we link against nosys.specs or you add syscalls.c
  2. Debug Configuration : in which we link against rdimon.specs, and we add a symbole (define) named DEBUG


In your source code initialise_monitor_handles() should appear within #ifdef DEBUG .... #endif
