hmm... I have not touched that file. Compiling for idr from cvs I see: timr@localhost:~/work/vercel/blob/src/blob$ ls -l blob* -rwxr-xr-x 1 timr timr 46520 Jan 28 14:12 blob -rwxr-xr-x 1 timr timr 46520 Jan 28 14:12 blob-chain -rwxr-xr-x 1 timr timr 45496 Jan 28 14:12 blob-rest -rwxr-xr-x 1 timr timr 77029 Jan 28 14:12 blob-rest-elf32 -rwxr-xr-x 1 timr timr 852 Jan 27 01:30 blob-start -rwxr-xr-x 1 timr timr 196 Jan 27 01:30 blob-start-chain -rwxr-xr-x 1 timr timr 34179 Jan 27 01:30 blob-start-chain-elf32 -rwxr-xr-x 1 timr timr 35805 Jan 27 01:30 blob-start-elf32 where blob has 13k of nulls on the end. blob-rest-elf32 contains this same block on the end of the code before the debug blocks.

I currently can't compile for idr because of compiler errors (SBI_SKCR undeclared in sa1111_init()), but this is the output from the last time I compiled it: erik@arthur:idr/src/blob >pwd /home/erik/src/sourceforge/build/idr/src/blob erik@arthur:idr/src/blob >ls -l blob* -rwxr-xr-x 1 erik users 32148 Jan 18 23:43 blob -rwxr-xr-x 1 erik users 32148 Jan 17 00:22 blob-chain -rwxr-xr-x 1 erik users 31124 Jan 17 00:22 blob-rest -rwxr-xr-x 1 erik users 76596 Jan 17 00:22 blob-rest-elf32 -rwxr-xr-x 1 erik users 852 Jan 18 23:43 blob-start -rwxr-xr-x 1 erik users 196 Jan 9 00:31 blob-start-chain -rwxr-xr-x 1 erik users 34465 Jan 9 00:31 blob-start-chain-elf32 -rwxr-xr-x 1 erik users 36382 Jan 18 23:43 blob-start-elf32 And this is with today's CVS version for LART (compiled with --enable-md5): erik@arthur:lart/src/blob >pwd /home/erik/src/sourceforge/build/lart/src/blob erik@arthur:lart/src/blob >ls -l blob* -rwxr-xr-x 1 erik users 24632 Jan 21 22:51 blob -rwxr-xr-x 1 erik users 24632 Jan 21 22:51 blob-chain -rwxr-xr-x 1 erik users 23608 Jan 21 22:51 blob-rest -rwxr-xr-x 1 erik users 65826 Jan 21 22:51 blob-rest-elf32 -rwxr-xr-x 1 erik users 640 Jan 19 00:47 blob-start -rwxr-xr-x 1 erik users 196 Jan 19 00:47 blob-start-chain -rwxr-xr-x 1 erik users 34466 Jan 19 00:47 blob-start-chain-elf32 -rwxr-xr-x 1 erik users 36162 Jan 19 00:47 blob-start-elf32 I can't really repeat your problem. I am using both my gcc-2.95.2 toolchain (available from the LART site) and the gcc-2.95.3 toolchain (available from LART site and arm-linux FTP site). Unless something is defining a non-null byte somewhere in the .bss segment or on the stack, I can't really see what's wrong.

just to confirn, if you hexedit your lart blob you do not what are the
last 100 bytes or so?
I'm building with:
./configure \
--with-linux-prefix=/home/timr/work/vercel/linux \
--enable-maintainer-mode \
--enable-clock-scaling \
--enable-memtest \
--enable-debug \
--enable-lcd \
--enable-jffs2 \
--enable-md5 \
--with-board=idr \
--enable-all-features \
arm-linux
make
lcd and clock scale are not yet supported.

My original 2.95.2 based toolchain uses binutils 2.9.5 and behaves OK, the 2.95.3 and 3.0 based toolchains use binutils 2.11.2 and 2.11.90.0.4. All gcc versions issue the same linker command line (with some differences in the -L flags), but so far only the 2.9.5 based linker works as expected. I'm trying to track it down further. I have a meeting tonight, could you add the following flag to blob_rest_elf32_LDFLAGS in src/blob/Makefile.am: -Wl,--gc-sections and try if that gives you a bootable blob image?
