ARM7TDMI problem

ARM7TDMI problem

[Hadi Aminzadeh]

Hi Dear,

I have a LPC2478 arm processor and want to use gcc to cross compile my
code in x86 for LPC2478
I use arm-linux-gnueabi-gcc to do that but (I think) the output of gcc
is an application that can be run in arm ported linux kernel but I
need Intel HEX-like format that can be programmed to micro controller
(I haven't any OS)
I haven't any idea what to do or what keyword I must search.

Regards,
Aminzadeh

you basically need a proper linker script for small embedded device.
please, see an example at http://www.dreamislife.com/arm/ -> lpc2106_gcc.zip
and search arm groups for similar one tuned for LPC2478...

What about using "gcc for arm" ?  Doing that in Google gave as the 2nd
hit:

http://www.gnuarm.com/

which is one of the many sites in the net providing prebuilt GCCs for
the embedded (no-opsys) ARM systems. Another site coming into my mind
was CodeSourcery which now seemed to be a part of Mentor Graphics:

http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/lite-edition

Of course all us NIH-attitude people will try to produce our own
toolchains from pristine FSF sources but for some the pre-made tools
may be acceptable... :)

Thanks for your replay
I find a linker script for my device (that tested with my board) and
used gnuarm pre-compiled binary and eclipse to compile my tested
simple LED flasher program. but no success :-(
you can see the output of eclipse. have any idea?

please show the 'simple LED flasher' source and 'arm-elf-objdump -hw lpc2478'.

the delay_ms() function was optimized at compile time to plain 'return'
you can see this with -fdump-tree-optimized gcc option.
and finally the hexdump shows .debug* sections in binary - there's no need
to waste eeprom resources with debuginfo.

ok I disable the optimization ( -O0 ) but nothing happend :-(
Is it possible to generate an lst file ? I think it can help to find problem.
