which 2.6 kernel can be run on db1550?

which 2.6 kernel can be run on db1550?

[rolf liu]

I just compiled 2.4.31 and run that on db1550. It works through a NFS
root file system. I am thinking of running of 2.6 on db1550. Which one
can be compiled by SDE and run this box?

I tried 2.6.12 and tried 2.6.12-rc6, but got no luck. They just don't compile.

thanks

I haven't switched over to 2.6.12, but I'm running 2.6.11 (checked out
from linux-mips on 2005.03.18) on a Au1550 based board. When I was
porting to my hardware, the default kernel worked just fine on the
DBAu1550. I'm using gcc 3.4.3 and 2.15.94.0.2.2 bintools.

I'm not sure what SDE is. I used buildroot to compile my toolchain and
make my root image.

I haven't had a chance to try 2.6.12 yet.

Thanks very much for the information.

SDE is the toolchain from mips, which is based on gcc 2.96.

I'll try 2.6.11 then

Just a quick warning that you should not be using the "SDE lite" package 
to build a Linux kernel. For that you need the Linux configuration of 
the toolchain, which is described here 
http://www.linux-mips.org/wiki/Toolchains#MIPS_SDE

I used SED to compile 2.4.31. It seems fine. but got no success on 2.6.*

Don't top-post, thanks.

http://gcc.gnu.org/gcc-2.96.html

Also, just in case it wasn't clear, the mainstream kernels from kernel.org 
don't always run too well on MIPS, pull one from the linux-mips.org CVS 
rather.

cheers

although 2.6.12 tag doens't exist and HEAD doens't compile (I checked it
yesterday)...

Yep, that happens when there is active development going on. Nonetheless, I'd 
stay with that one and try to fix what is broken - in my experience these are 
only small oversights, not real trouble. Also, for such things it pays to 
sometimes get on #linux-mips an irc.freenode.net.

I found this in "include/linux/compiler-gcc2.h". 
"""
/* GCC 2.95.x/2.96 recognize __va_copy, but not va_copy. Actually later GCC's
 * define both va_copy and __va_copy, but the latter may go away, so limit this
 * to this header */
#define va_copy                       __va_copy
"""

That's not correct seems my gcc (2.96) defines va_copy.

Another thing in "arch/mips/kernel/ptrace.c" line 273:
"""
                case DSP_BASE ... DSP_BASE + 5:
                        if (!cpu_has_dsp) {
                                ret = -EIO;
                                break;
                        }
                        dspreg_t *dregs = __get_dsp_regs(child);
                        dregs[addr - DSP_BASE] = data;
                        break;
"""

dregs variable is declared in an incorrect place (no opening block here)...

Hope it helps.

        Francis

I just checked out the top of the linux-mips tree, which is 2.6.12.
It compiles and runs fine on the Db1500.  I'm now doing the same
for the Pb1550, but I don't suspect any problems because I have
been using it for quite some time.  It looks like it is time to update
the default configuration files, but accepting the default answer for
any new options seems to work fine.

I am using gcc-3.3.3 or 3.4.1, and some 2.15 version of binutils.
Using your MIPS SDE tools is going to be a problem because
they are not up to date with what the source code requires.

Thanks.
