Re: porting reversible on arm/mips

[paawan oza <paawan1982 at yahoo dot com>]

Hi All,

In conclusion we have following approaches to go ahead with.

1) have qemu or skyeye on windows and get the arm kernel on to it.

2) Using arm-elf-gdb, and use 'target simulator' command, and cross compiling test programs for arm.

1st gives me complete environment.
2nd may be a part of it.

any thing is ok as long as that gives smooth start.
I will try to setup qemu first and see.

Thanks for your help.
Regards,
Oza.

If you configure gdb as "arm-elf", gdb will build with
its own linked-in arm simulator which you can use by
means of the gdb command "target simulator".

That is correct.   You can build arm-elf-gdb on x86 host.
You will probably want to build arm-elf-gcc and asm and linker,
so that you can compile test programs to simulate.
