zImage.embedded

[Guillaume Dargaud]

Hello all,

I'm not sure what kind of error this is. I'm trying to generate a kernel 
image suitable for network boot and it seems to fail at the very end (wrong 
target ?)

$ make ARCH=ppc CROSS_COMPILE=powerpc-linux-uclibc-  znetboot

powerpc-linux-uclibc-objcopy -O elf32-powerpc arch/ppc/boot/simple/zvmlinux 
arch/ppc/boot/simple/zvmlinux -R .comment -R .stab \
                -R .stabstr -R .ramdisk
cp -f arch/ppc/boot/simple/zvmlinux arch/ppc/boot/images/zImage.elf
rm -f arch/ppc/boot/simple/zvmlinux
cp arch/ppc/boot/images/zImage.embedded /tftpboot/zImage.embedded
cp: cannot stat `arch/ppc/boot/images/zImage.embedded': No such file or 
directory
make[2]: *** [znetboot] Error 1
make[1]: *** [simple] Error 2
make: *** [znetboot] Error 2

is the file zImage.elf my proper network image ?

What bootloader is on your board?  zImage.elf *might* be the proper
image.  If you're using u-boot, then you want to build a uImage
instead.

I... ahem... what would you recommand for a ML405 ?
Builroot gives to options of U-Boot or Yaboot. Haven't tried either yet. 
Will do on tuesday.

I don't know if Xilinx has another solution (I remember seeing some boot 
function in the API, usable from a standalone elf file).

zImage.elf is what you want.  If you *do* get u-boot building on your
board, then you'll want a uImage; but zImage.elf will work for you
now.

I'm trying to compile u-boot with buildroot, but it fails with:

                /usr/bin/make -j1 -C 
/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2 
\
                ""_config
make[1]: Entering directory 
`/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2'
make[1]: *** No rule to make target `_config'.  Stop.
make[1]: Leaving directory 
`/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2'
make: *** 
[/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/u-boot-1.3.2/.configured] 
Error 2

Apparently it expects a BOARD_NAME variable, but I don't know what to put in 
it (I looked at the makefile and can't find the ml405 referenced in there).

I think you need to figure out how to build u-boot for your board
outside buildroot, before you try to build it inside buildroot.

Working on it...

While I do that, I have a side question:
is it possible to boot off a first kernel on a local partition, but tell it 
to tftp boot off another kernel instead ?

The rational is that I have a working system on a card in my embedded 
system, but if possible I'd like to have it boot off the latest version 
available on the network.

And if not available, simple boot using fallback parameters.

Makes sense ?
