OE cross toolchain for SH4

[tom_van]

Arris,

could you please look at http://volny.cz/vanekt/sam/elfpatcher-oe.tar.gz
and eventually commit it to svn? elfpatcher is part of my arfix and may be useful
on arm TVs too. Native version is for prepatching firmware on pc.

Thanks, Tom

tnx for the nice app. commited,

there was a bug in gcc for sh4, so if you use gcc-cross from oe/branch pls. rebuild it

Code: Select all

svn up
cd build ; . ./env.source ; bitbake -c clean gcc-cross ; cd -
cd build ; . ./env.source ; bitbake -v -D gcc-cross ; cd -

Before we rebuild can you add -m4 to target CFLAGS? Or is there a compatibility reason why not?

you can enable oe/conf/machine/include/tune-sh4.conf in oe/conf/machine/T-RBYDEUC.conf if you realy like, i didn't tested any "optimisation/tuning"
but if you do so pls rebuild the full toolchain

ps: somebody need applications like gdb slsnif dosfstools strace lsof coreutils i2c-tools ntop ibusb?

I know about oe/conf/machine/T-RBYDEUC.conf and disabled tune-sh4.conf.
-m4 (generate sh4 code) is used in kernel and I'm not sure if it is default sh4-gcc mode.

I use gdbserver and cross gdb from STLinux2.3 and strace. It would be nice to have gdb 7+.
I tried compile it from source, but gdbserver does not like such old libc.

Keep up good work

I have arfix-sh package ready to commit. I'd really appreciate dev access to svn.

m4 "should" be default

is included in svn, fix for sh4 also.
hard way is to rebuild binutils, easy way remove one include file before your build gdbserver
i wrote infos into gdb_7.0.1.bb

Keep up good work

tom_van added as a project membership. Also tskitishvili added for SH4 works like telnet enabling.
Thanks guys

Good. Starting rebuild...

something goes wrong on movig around the directories, i review the compile and svn logs since today morning and try to build a diff .
i hope error is in glibc and not in compiler (now i made new checkout and rever just glibc to r234, this hopefully ends with a compiler error in math dir at __atan. if its true just the cfalgs are to changed to disable -fomit-frame-pointer)

sry
