Re: Linux 2.6 boot failure on xup virtex II ppc405

[saadia dhouib <saadia_dhouib@yahoo.fr>]

Hi all,

After booting successfully the kernel without a root file system.

I  installed a file system on the flash disk. I used: BusyBox 1.12.1, and
the script mkrootfs.sh (written by=20

Wofgang Klingauf) to generate the rfs.

=20

I changed the boot arg in the kernel configuration as follows:

 [*] Default bootloader kernel arguments                                   =
                                =20
=E2=94=82 =E2=94=82=20
  =E2=94=82 =E2=94=82                                      (console=3DttyUL=
0,9600
root=3D/dev/xsysace/disc0/xsa3 rw) Initial kernel command string=20

=20

Then I rebooted the kernel, and there were those errors :( :
