$ arm-elf-size.exe a.out
text data bss dec hex filename
41920 1512 8028 51460 c904 a.out
I suppose that this means the binary will be 51460Kb in size?
I am using a Phlips 2106 processor with 128Kb EEPROM and 64Kb RAM.
Do you think I can fit in LwIP + PPP + Zlib in this?
The linker is giving me errors :
$ arm-elf-gcc -I../../ecos_install/include hello.c

I'm sorry, but the error messages are in french.
From what I gather, the code is too big for RAM and ROM?
"the address 0x2624c from a.out in section .text is not in the rom region"?
