AW: [uClinux-dev] busybox-error buildung uClinux
Hallo, here is the errorprint... I use uClinux-dist from January, 30th 2007 with Patch from March, 5th 2008 I've also patched the linux-2.6.x-folder with OSADL Preempt RT Patches The Kernelversion is now 2.6.24-uc0-rt1 I'm building for NET+ARM 50 Regards Michael -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von David McCullough Gesendet: Mittwoch, 2.

CONFIG_LIB_ZLIB is already set on y. I just ran make oldconfig an make. but still got the ld-error and the busybox unstripped error. But I've checked my old uclinux(without preempt-rt) and I've seen, that there I've got the same errors, but they are ignored from the make-environment. how can I ignore them in my actual version. The old version runs without any big problems!! Hmm, not sure. I think I need to see the full build output. DO the following and send in the ouput: make single 21 | tail -n 100 /tmp/errs.txt And send me the errs.txt. Make sure it has the error and the mtd-utils stuff in the errs.txt file, if not increase the 100 a bit ;-) Also, which dist was that ?

Hello, I think here is the beginning of the problem. /usr/local/lib/gcc/arm-linux/3.4.4/../../../../arm-linux/bin/ld.real: cannot find -lz collect2: ld returned 1 exit status make[3]: *** [mkfs.jffs2] Fehler 1 make[3]: Leaving directory `/home/u011514/uClinux-dist/user/mtd-utils' make[2]: *** [mtd-utils] Fehler 2 Do I not have to use ld instead of ld.real? How can I switch to ld? ld.real and ld are both fine, the uclinux flat toochain renames ld to ld.real so you do not need to worry about this. The real problem is the: ld.real: cannot find -lz Looks like the mtd-utils need to have zlib enabled in the build. Because I am lazy and don't remember where to find this in the make xconfig, do this. Edit config/.config, find the line containing CONFIG_LIB_ZLIB and change it to: CONFIG_LIB_ZLIB=y save then run: make oldconfig make And you should be away ;-) Cheers, Davidm -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von [EMAIL PROTECTED] Gesendet: Montag, 30.

Can you run the make with V=1, eg make V=1 We need to see what the actual command line trying to be run is. the line posted is not the problem. noticed how it says ignored. since he's running in parallel, something else failed. Run: make single to see where it actually fails. If I missed the fact that it is an older uClinux-dist then run: make NON_SMP_BUILD=1 Cheers, Davidm -- David McCullough, [EMAIL PROTECTED], Ph:+61 734352815 Secure Computing - SnapGear http://www.uCdot.org http://www.snapgear.com ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
Re: [uClinux-dev] ROMFS troubles
Jivin steven taffs lays it down ...
David thanks for the reply
ok flthdr romfs/bin/sh reads
Magic:bFLT
Rev:4
Entry:0x44
Data start: 0xe720
Data end:0x111f0
bss end: 0x12750
stack size: 0x1000
Reloc start:0x111f0
reloc count:0x42
FLags:0x2(Has-PIC-GOT)
therefore the file system is XIP right?
Almost, it means your application is XIP capable, which is good.
You also need and XIP capable FS to make it all work.
next I added in the bFLT debug code and commented out the line below in rc
script just to see if that helped
/bin/expand /etc/ramfs.img /dev/ram1
and I got the output below as you can see the kernel gets a little
closer however it still kills sh. looking at the output romfs is only
taking up
Just a thought, which shell are you using ? sash would be the best
choice.
The sh above is using 10K of data + 4K of stack.
80108 bytes
20612 bytes
in total 98kb before the kernel crashes. The kernel reports on startup
Memory: 900KB available (690K code, 80K data, 4K init)
the romfs takes 98k then the kernel crashes so there should be 900kb - 98Kb =
802kb left however the kernel moans saying
Free pages: 172kB (0kB HighMem)
Where is the other 802kb - 172kb = 603kb going ? anyone have any ideas ?
Freeing init memory: 4K

You are doing well here in my opinion. init is running, it has run
/etc/rc in a shell and that has run several commands like mount and
hostname.
It is quite likely that your memory has become fragmented. Which kernel
memory allocator are you using ? You probably want SLUB or SLOB.
If you really want to see the command prompt then set your kernel
command line to:
... init=/bin/sh
that will skip all the rc scripting and give you a prompt. From there
you can try things and see what hurts and what doesn't,
Cheers,
Davidm

Hi guys
ok when swapping to uClinux-dist-2005 I forgot to add mtd mtdblocks to
the vendor makefile I have now added these. However I still get the same
errors I have been reading a past post and I think the problem is that
uClinux does not save space after _ebss for the ram mtd drive on a arm7
device. I think to use uclinux.c I need to change init.c and maybe more
files within the mm folder.
I decided to write my own map file actelm7.map and used map_rom to probe
the flash device and split it into partitions. I got the following output
from the kernel below, as you can see the shell starts up however when it
tries to load ramfs.img the kernel looks like it runs out of memory. I have
one meg of ram within my system the kernels data takes up about 100k the
rest of the kernel is XIP therefore I should have about 900k free. The
romfs is also
