Hello all
I am using RTEMS 4.10 for my i386ex custom board. Host operating System is
ubuntu 11.04
I have configured my RTEMS as
--target=i386-rtems4.10 --prefix=/opt/rtems-4.10 --disable-itron
--disable-posix --disable-networking --disable-multiprocessing
--enable-rtemsbsp="i386ex"
By this configuration, i get sample application "hello world" executable of
size 1.02 MB
text data bss dec filename
118665 3908 7794 1fd3f hello.exe
By converting it into downloadable hex file
i386-rtems4.10-objcopy -O ihex hello.exe hello.hex
packhex <hello.hex >rtemshello.hex
The final downloadable image is rtemshello
text data bss dec filename
0 122573 0 122573 rtemshello.hex
The file size of rtemshello.hex is 246KB, whereas the available ROM in my
board is 128K, is there any way i can reduce this size upto 128K so that i
can download it into ROM?
Thank you for your time
Regards
