Re: Patch: FW:Xilinx: BSP: Updated ML405 to match hardware used for testing

[Guillaume Dargaud]

Hello all,

I'm trying to get things up and running on a Xilinx Virtex-4 ml405 board, 
and as such I've been trying to figure out the following recent message to 
the list:
http://patchwork.ozlabs.org/linuxppc/patch?person=1226&id=17037

I don't understand what this patch applies to: it references files such as 
ml405_defconfig which are not part of the normal kernel tree and which I 
cannot find anywhere. Is there some other kind of patch that needs to apply 
first in order to get for instance CONFIG_XILINX_DRIVERS, 
CONFIG_XILINX_EMAC, etc...

Thanks

It applies to Xilinx's git tree of the Linux kernel.

Fair enough.

OK, I managed to install git, download the Xilinx kernel source tree, 
integrate it into root and compile it successfully...

Now I'd like to understand this ml405_defconfig file. I cannot replace my 
.config with it because it gives me:

$ make ARCH=ppc linux26-menuconfig

So my question is that even with a full (?) Xilinx kernel, there seems to be 
missing drivers. Does this have to do with the BSP ?

Thanks

[Guillaume Dargaud]

I should add that I've tried several things:
- compile the Xilinx kernel as indicated in my previous message.
- compile it with just the xparameters_ml*.h files added
- copy all the files from the BSP into the (Xilinx) kernel tree
- directly generate the BSP into the (Xilinx) kernel tree

For instance, the last one still gives me:
.config:117:warning: trying to assign nonexistent symbol WANT_EARLY_SERIAL
.config:122:warning: trying to assign nonexistent symbol BUBINGA
.config:123:warning: trying to assign nonexistent symbol CPCI405

Two more things:

$ make ARCH=ppc ml405_defconfig
cp  .config
cp: missing destination file operand after `.config'
Try `cp --help' for more information.
make: *** [ml405_defconfig] Error 1


And on the page http://wiki.secretlab.ca/index.php/Linux_on_Xilinx_Virtex
which I've been studying closely, I also tried the Secret Lab repository:
$ git clone git://git.secretlab.ca/git/linux-2.6-virtex.git

Neither of these will work.

Did you check out the head of the tree?

I'd suggest starting over with a fresh tree.
1) Copy the xparameters file, overwriting the appropriate xparameters
file in the git tree.
2) make ARCH=3Dppc ml405_defconfig
3) make ARCH=3Dppc all

I know Grant has been having problems with the secretlab git server
recently.

It doesn't... Which makes me wonder if my problem may be with the boot
itself.
Once I have my zImage properly (?) compiled, I create an ACE file thus:
$ xmd -tcl genace.tcl -jprog -board ml405 -target ppc_hw -hw system.bit -elf 
zImage -ace Kernel26.ace
But then nothing happens when I boot with it.

You mean svn head ? Yes.
Something escapes me here. I pull the complete kernel git tree from Xilinx 
and
when I menuconfig it, it removes the Xilinx additions ('nonexistent symbol 
')...

I'm not very knowledgeable of the kernel organization, so I don't know what
this means, but I imagine there's a relation between 'XILINX_ML40x=y' in
.config, Kconfig which holds the help text and the .h/.c driver files
themselves. How can I check that the whole package is sane ?

One detail, I'm not doing 'make' from the kernel directory, but from the
buildroot directory, this way I'm sure it's compiled with the appropriate
cross-compiler and environment. Maybe targets such as ml405_defconfig are 
not transmitted properly from one make to the other. Anyone who knows 
buildroot care to
comment on that ?
