[ECOS] comiling and running 'hello world'

[Bier Meister <bier dot meister at freenet dot de>]

Hi,

I compiled the 'hello world!' example from the eCos 2.0 user guide using 
the following command:
(my current directory is <proj>/proj_install/lib)

arm-elf-gcc -g -I ../include/ hello.c -L ./ -Ttarget.ld -nostdlib

I try to run it in the simulator using the following command: $ 
arm-elf-gdb -nw a.out

The result is this output and thats it. i can only stop gdb using ctrl+c


$ arm-elf-gdb -nw a.out

(gdb) run

*sim: unknown SWI encountered - ffffff - ignoring*





However, if i issue the comiple command : $ arm-elf-gcc -g -I 
../include/ hello.c -L ./
and then try to debug the executable in the simjulator, it works just fine.
