Hi Pradeep, If you are using the MontaVista/Xilinx driver
for sysace for linux 2.6, the CONFIG_CMDLINE item in .config should have root=/dev/xsysace2 rw in it. From the text below it’s not
clear what driver you are using. If you are using a different driver, you may
be able to search for #define MAJOR_NAME in the source code of the sysace driver. I
believe that will indicate which device name you should use in the
CONFIG_CMDLINE. As you probably already know, the ‘2’
in ‘/dev/xsysace2’ refers to the partition number it should use –
partition 2 in this case. For Problem 2: Do you see any error leds
light up on the board? It’s possible that the drivers you are using for
one or both of those cores is not meant for the version of the cores you are
using. The core most likely to be suspect is the TEMAC soft core, as that has
changed recently. Even though you are using the hard TEMAC core, there is a
soft wrapper around it to connect it up to the bus and what not. This soft wrapper
has changed from version 2 to version 3 not too long ago. While the TEMAC
driver that MontaVista has (and I believe posted to this mailing list) is for
version 2 of the soft TEMAC core. Hope this helps, - John From:

[mailto:[EMAIL PROTECTED] On Behalf Of Pradeep Sampath Hello Ameet/Ming, First of all really appreciate your inputs on this... Problem 1 : I was using the factory shipped compact flash as is which comes with a
DOS FAT16 partition and a linux 83 partition with ext3 filesystem. I tried
it on 2 factory shipped CFs and its the same behavior - . When i
plug-in the CF card reader to the linux box it always reads it as
"sda" and in the linux2.6.17.1/Documentation/devices.txt - sda is the
device file for SCSI disk devices. Wonerding how you guys configured the root
option as "/dev/xsa". Now i re-formatted my CF, created a ext2 filesystem using busybox-1.1.0
like the BYU instructions. Created 2 partitions on CF card 1. FAT16 partition
& 2. linux partition and then created 1. dos file system using mkdosfs and
2. linux ext2 filesystem using mke2fs. But the problem still persists and i get "Please append a correct
"root=" boot option :" :( Problem 2: After i included the TEMAC driver and sysace drivers,
the kernel just hangs. I thought i'll fix problem 1 before i get to
problem 2... With your help i am getting the confidence that i can make this all
work! thanks once again. -Pradeep
