Hello everybody! The ARM Simulator does support different Modes. I just have had the wrong arm-elf-gdb in my PATH. It was the last stable version: GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc. Even at the beginning of "start" the cpsr is equal to 0x10; I have added a mode switch to user mode to crt0.S and will install the proposed swi handler. Thank´s a lot, Jens-Christian Am Mon, 22 Jan 2001 schrieben Sie: > In message <01012211514701.02376@lab04>, Jens-Christian Lache writes: > >Unfortunately the ARM simulator does not support the several CPU modes, that > >the ARM7TDMI has.
