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
This should work.
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.
[...]
.config:773:warning: trying to assign nonexistent symbol XILINX_ML40x
Did you check out the head of the tree?
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 ?
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
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=ppc ml405_defconfig
3) make ARCH=ppc all
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 ?
