XUP Virtex II p with Linux 2.4 - Question

[rodolfo]

Hi everybody!

I subscribe on this list today because i have some problems with linux
kernel 2.4 compilation. I'm using EDK/ISE 9.1i, crosstool-0.38 . I follow
this sites:

- http://www.cs.washington.edu/research/lis/empart/xup_ppc_linux.shtml
- http://splish.ee.byu.edu/projects/LinuxFPGA/
- http://www.crhc.uiuc.edu/IMPACT/gsrc/hardwarelab/docs/kernel-HOWTO.html

I have a lot of error like this: "can not found ...", "undeclared first in
this function...". But i could solve them! Now the problem is:

../common/ns16550.c: In function `serial_init':
../common/ns16550.c:63: error: `XPAR_UARTNS550_0_CLOCK_FREQ_HZ' undeclared
(first use in this function)
../common/ns16550.c:63: error: (Each undeclared identifier is reported only
once
../common/ns16550.c:63: error: for each function it appears in.)
make[2]: ** [../common/ns16550.o] Erro 1

make[1]: Saindo do diretório

Anybody can help me? i'm new in this world (fpga - linux)!

You should switch to using a 2.6 kernel.  The 2.4 stuff is difficult to support.

See my notes here:

Hey everybody, 

I'm in trouble;

1) The EDK flow: I set the OS in the Software Plataform Settings to
linux_2_6 version 1.00.a. after that, in OS and Library section I have to
fill out the fields "memory size" , "connected_periphs" , "ramdisk size"
... ?  How would I do it ? 

2) Do I place xparametera_ml300.h in /opt/ELDK/ppc_4xx/usr/src/linux-2.6.15
? if not where?

3) I downloaded "ppc-2006-01-11.iso" from denx (ELDK) website and I'm
trying to follow their instructions for ppc 4xx plataform.
[ website: http://www.denx.de/wiki/view/DULG/ELDK ]

In /opt/ELDK/ppc_4xx/usr/src/u-boot-1.1.4/ I do:

"make distclen" and  "make ml300_config" are ok! After "make all" in  I've
got an error:

a - ppc_longjmp.o
a - ppc_setjmp.o
a - stubs.o
make[1]: *** No rules for processing the target `hello_world.srec', needed
by `all'. Stop.       --> note: "TRANSLATION FROM PORTUGESE"
make[1]: Exiting `/opt/ELDK/ppc_4xx/usr/src/u-boot-1.1.4/examples'
make: ** [examples] Error 2

Can you help me, please?

Thanks in advance,
Rodolfo Galvão.

You should download a current release of the linux kernel.  Don't use
the one that comes with ELDK.

in arch/ppc/platforms/4xx/xparameters/xparameters_ml403.h.  If you're
using the ml403 reference design, it is already there.  If you're
using a custom design then you'll need to replace it.

See here for hints:

This is an old release of ELDK.  You should probably move up to a more
recent release.

You're using an ancient copy of u-boot that breaks with certain
versions of the 'make' program.  You should try using a recent release
of u-boot.  Alternately, you can hack the u-boot makefile to not build
the examples directory.

Cheers,
