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.

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.

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)
Cheers,

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
