Can you post your toolchain information? Compiler version is the most
important thing here.

Hi Paul,

> important thing here.
I'm using an rpm-based cross toolchain from
http://rpm.sh-linux.org/rpm-2004/host/RPMS/:
gcc-sh-linux-3.4.4-1.i386.rpm
binutils-sh-linux-2.16.1-2.i386.rpm
glibc-sh-linux-2.3.3-27.12.noarch.rpm
glibc-sh3-linux-2.3.3-27.12.noarch.rpm
I notice there are some newer toolchains on that site now, which of these
should I be using?

I've upgraded to the gcc 4.1.1 rpm (also from rpm.linux-sh.org). The
problem is still there but the messages I see are different: The BUG has
been replaced with "map_probe failed".
physmap platform flash device: 01000000 at 00000000
physmap-flash physmap-flash.0: map_probe failed
Obviously later on I get a panic as it can't see its root fs.
The same revisions as before are good and bad, and I still get no console
output from commits in-between the two so I'm unable to bisect further.

Sorry, that should be rpm.sh-linux.org.
Doh, since Friday Linus's tree #errors on gcc 4.1.{0,1}. Is there a more
recent version available as a binary, or should I build my own cross
toolchain (crosstool?)?
Is there a specific gcc version you'd recommend for sh cross compilation?
Thanks for your help,

There are a couple binary toolchains at:
http://userweb.kernel.org/~lethal/toolchains/
beyond that, you can find some more links on the wiki.
I generally stick with gcc 4.2.x, although have been doing 4.3.x also
recently. The binutils versions tend not to matter too much, in that they
tend to have very little churn in the sh backend.

Thanks Paul,
With your gcc 4.2.1 toolchain and today's linus git tree my platform's
physmap flash works again. I also tested the "bad" revision from my
bisection and this also works fine with gcc 4.2.1.
I'll use 4.2.1 from now onwards, so I'm happy, but if this is still
something you still want to fix I'm happy to test patches with 3.4.4.
Steve

I did test these patches with a gcc 3.4.5 version that was fairly close
to standard, so I expect that the version of 3.4.4 you are using has
quite a few patches. In any event, gcc 3.x is old enough now that there
are not many people still building on it, so I wouldn't worry about it.

Sorry for the late reply (change of hardware), just
wanted to throw my 2-cents in there. The main problem
for SH3 hardware in the past has been glibc,
any version below glibc 2.3.4 for instance couldnt create
dynamic linked binaries.
My reference toolchain (= know it works) is based
on gcc 3.4.5 and glibc 2.3.5.
