Hi all, I'm having some problems with the rootfs:
If I use an initial ram disk, such as the initramfs from ELDK4.1 to build
an zImage.ielf file, I've got this log:
It looks like no image have been loaded!!! I have supplied a directory,
where I''ve mounted the EDLK ramdisk image, to the kernel and let him to
build the ramdisk (to avoid mistakes):
loaded at: 00400000 006691A0
board data at: 00667124 006671A0
relocated to: 004040A8 00404124 <-- I think that here
should be line showing the direction where the
zimage at: 00404E99 00666C26 RAMDISK have been
loaded, I've seen it on other boot logs!!!

The ramdisk have not been loaded to memory, or anything similar!!!

I've also tried to boot from SystemACE but I've got a partition table error
( xsa: unknown partition table ). I've reformat my CF card for some times,
and nothing have change:
The partition table must be MS-DOS, type 6 on fdisk.
That's the fdisk partition table:

That's the dump of my CF Card maybe some one could send me a dump of yours.
One of my tries, after using the CF Card in the XUPV2P, I get this message:
El dispositivo no contiene una tabla de particiones DOS válida ni una
etiqueta de disco Sun o SGI o OSF
Building a new DOS disklabel with disk identifier 0x0eb5b431.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Atención: el indicador 0x0000 inválido de la tabla de particiones 4 se
corregirá mediante w(rite)
But It didn't repeat anymore.. So I suppose that the CF card isn't valid for
the SystemAce of the board!! But I don't know why??
I don't know what is the problem, if anyone knows, reply please
Thanx
PD: Sorry for writing so large messages but I've included all the info I've
recover..
