Newbie and linux on virtex-II ppc

Newbie and linux on virtex-II ppc

[schardt]

Hello,

im a student from germany and i try to run linux on a virtex-II with
integrated powerpc.
i use the developer board DS-DB-2VP4/7-FG456 from Memec ( i think its
now avnet)

i hope my questions are not too stupid :-)

what is running :

  - Xilinx EDK project (standalone program running fine, and BSP files
are generated)
    the project has only one UARTLITE, 82MB SDRAM and a few kByte
blockram, and the systemace interface
 
  - crosscompiler toolchain works

  - after modified some defines in the xparameters.h i got a linux 2.4.
kernel (linuxppc) without compiler errors
    and yes, the uartlite driver is enabled :)


but, when downloading the zImage.elf via XMD to the SDRAM and starting
it with the run command nothing happens , or  i think that nothings
happens because the serial port is quiet.

is it possible to run a kernel that way ? or need i some kind of
bootloader ?
or is this complete the wrong way ?

Regards
Georg

I strongly recommend trying to bring up a 2.6 kernel, it's much easier.

Don't modify xparams by hand; it's not worth the trouble.  Go into
software setting in your EDK project and select 'linux-2.6' as the OS.
 Generate the libraries and copy the generated xparameters_ml40x.h
into your kernel tree.

You can always use System.map in the kernel tree to find out where
__log_buf was linked to.  Look at that location with the debugger to
see if there is a crash message that didn't get printed out.

Yes, I use this same method to bring up a kernel on Virtex boards
which don't have a bootloader.

Probably, but you can use the montavista 2.4 option also.  You're only
interested in the xparameters.h file, not the whole BSP.  (Letting EDK
generate files into your kernel tree is scary)

Re: Newbie and linux on virtex-II ppc

[schardt]

Good morning,

last night i got a 2.6. kernel ready and ive got a "Now booting the
kernel" message on the serial port *yeah* :)

... but nothing more :(

the __log_buffer says something like "Linux version ..."
is there a more useable way to read out the buffer ?  i use the xmd
debugger and the mrd command

Regards
Georg

You've got 2 choices:
1. use the new sysace driver; it's already in mainline.  The new
driver is faster, but it doesn't handle hotswap of the CF card (yet)
2. use the EDK driver; easiest way is to use my tree which already has
it merged:  http://git.secretlab.ca

But where in menuconfig could i find the sysace driver ? i'm blind, i
think :)

i made an EDK update and now i have the linux_2_2 os in the software
options. the bsp with all drivers is generated.
and now ?
 - copy to kernel tree 
 - use the xmake  to build the kernel, or make ?

and why is there no dokumentation :)

Thanks a lot

Which version of kernel are you using?  The new sysace driver was
merged into 2.6.22

Don't use EDK to build you're kernel.  It's too fragile and you need
to use the *exact* version of kernel that EDK expects.  You're better
off to manually copy the xparams file from the generated BSP.  (ie.
Don't let EDK know where your real kernel source tree is)

Care to write some?

wuh ? i dont need all the driver from the generatet bsp files ? what
about the gpios and leds  ?

i compile the kernel with a self made cross toolchain, not with the edk.
until now i copied the bsp files into the kernel tree (modfied some
defines) und compile with "make zImage". But know with the linux_2_6
option there is some more stuff in the bsp directory and i don't know
what to do with :)

Should be under drivers->block devices then.

Most drivers are already in my tree; any that are missing you can copy
over manually.

Re: Newbie and linux on virtex-II ppc

[schardt]

Okay, im really blind i think, so i started again :

- 2.6.22 kernel from kernel.org
- cp /arch/ppc/configs/ml300_defconfig .config
- edit Makefile to use ARCH=ppc and CROSS_COMPILE=powerpc-405-linux-gnu-
- copy xparams
- make menuconfig -> no SYSACE blockdevice :((( *aaaaargh*

i will try the grant kernel now :)

BTW, "make ml300_defconfig" does this for you.

Re: Newbie and linux on virtex-II ppc

[schardt]

Step by step i becomes running :)

kernel is booting, root-fs is mounting on systemace, busybox compiled
and rootfs installed (i used klingauf's mkrootfs)

but now it says:
[    2.964978] Freeing unused kernel memory: 92k init
[    3.081332] Warning: unable to open an initial console.
[    3.306406] request_module: runaway loop modprobe binfmt-4c46
[    3.375612] request_module: runaway loop modprobe binfmt-4c46
[    3.446800] request_module: runaway loop modprobe binfmt-4c46

and i don't know what this is :(

Can give me a hint, where to look ?

thx
Georg

Re: Newbie and linux on virtex-II ppc

[schardt]

me again :)

i added a /dev/ttyUL0 (mknod ttyUL0 c 204 187) device and and a console
link to it.
no warning anymore, but i think i'm listen on the "wrong" console ??? i
see bootmessages
and an errormessage from init ("init: can't open /dev/null: no such
device or directory")

but the messages from init.d/rcS did not appear

this is my inittab (from klingauf mkrootfs):

::sysinit:/etc/init.d/rcS
::askfirst:-/bin/sh
::ctrlaltdel:/sbin/reboot
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
::restart:/sbin/init
::respawn:/sbin/getty 9600 tts/0

Yeah, you don't want a symlink, you want a console device node instead:

mknod /dev/tty 5 0
mknod /dev/console 5 1

I would say you need to add a /dev/null device node, or fix it's
permissions.  :-)

mknod /dev/null 1 3

?

You should check that /etc/inittab is using the correct device.

[Ming Liu]

Dear Georg,

>or is this complete the wrong way ?

Yes, you can. Actually what I did is to include a bootloop in the hardware 
bitstream and that will keep your CPU waiting until the kernel's running.
