Sergei - Thank you very much. The .gdbinit script, especially adding to the device tree did the trick.

Hi If you do not sure, first try GNU toolchain from eCosCentric ftp://ecos.ecoscentric.com/pub/ecos/gnutools/i386linux/ > I then created a PSIM.ecc file and built the library and tests. Is there something special in PSIM.ecc?
