Hi,
I have the same problem, program stuck at bkpt 0xab, but I do not use serial wire interface (SWI). The Ulink2 is configured JTAG and SWJ checkbox is noch marked. My program runs before I added C++ code (a mix of c and cpp files - main() is in a standerd c file), sprintf() is used now - but not printf(). Any ideas?
This issue is specific to the ARM RVCT C library. Agreed, ARM should spend more time providing hands on examples in the documentation. But meanwhile you should have found some examples yourself. Like for instance "%PROGRAMFILES%\Keil\ARM\Examples\Hello\Retarget.c". Hopefully this will give you some more information.
When supported by the tool chain, semihosting is a very useful mechanism in certain situations. If you care, read some background information here: infocenter.arm.com/.../Bgbjjgij.html

Hi Marcus,
last questions, otherwise I use an other development system: 1) Is it possible to get _sys_open handled like _sys_exit? 2) Can I link the softinterrupt bkpt 0xab to an (empty) function of mine? 3) Could 2) help?
