Hello, Kumar!
Thank you again for your help...
The inscription of the CPU says:
PPC8540 PX833LB
2L71V MSIA
QEAD0412
(Yes, there is a heatsink on it ;-)
root@PM854:/cdrom/crux/base$ cat /proc/cpuinfo
processor : 0
cpu : e500
revision : 2.0 (pvr 8020 0020)
bogomips : 823.29
Vendor : Freescale Semiconductor
Machine : mpc8540ads
clock : 825MHz
PVR : 0x80200020
SVR : 0x80300020
PLL setting : 0x5
Memory : 256 MB
I hope that this is current...
Where can I find more information about the SVR?
(I had a look to the Errata Sheets... but there is no
overview of the different silicons.)
Up to now, the Panic didn't appear again - I didn't
change anything yet...
I just try to setup a new system (CRUX) on the attached hdd.
Best greets,
Clemens Koller
