Hi all,
I'm trying to build a firmware for an ARM7TDMI platform (no MMU), which means
uClibc won't support ELF files and requires I use FLAT executables.
Unfortunately I can't figure out how to make this work. I had to edit the
Makefile as it was complaining about missing crti.o files, but I created dummy
ones and that seemed to work. I'll send a patch through for this if I can get
the whole thing working.
But the rest of my buildroot-generated toolchain seems to insist on producing
ELF files. If I try to force use of elf2flt I get confusing errors:
arm-buildroot-linux-uclibcgnueabi-gcc test.c -o test -Wl,-elf2flt
buildroot/host/usr/arm-buildroot-linux-uclibcgnueabi/bin/ld.real: error: no
memory region specified for loadable section `.ARM.extab'
collect2: error: ld returned 1 exit status
What does this mean? Do I need to do anything special when compiling the
toolchain to use FLAT binaries, other than enabling elf2flt support? Can I
make GCC generate FLAT executables by default without specifying -Wl,-elf2flt?
Many thanks,
Adam.
