I made an Ace file with my Kernel and load it with the Flash Card.
I made the Initial release CF image on the card and copied my ace file in an folder, from which I boot with the DIP-Switch. If I used
"console=ttyUL0 ,9600 root=/dev/xsysace/disc0/part2 rw "
in the Kernel config booting aborts like this:

what is the Problem here?
What should I consider when I configure the kernel, what when building an rootfs?

Greetings
Joachim

You're probably missing the /dev/console device file

I'm also having some problem with my systemace file system. I'm working with secretlab git, and I try to mount the CF card with xsysace and with xsa, but in both cases it can't mount the rootfs:

[    3.547926] Kernel panic - not syncing: VFS: Unable to mount root fs on

unkn)

Does this mean that I have configured incorrectly the file system options in the kernel??
I have read that the solution to this is to change the DOS/FAT/NT Filesystem option to the below configuration:

<*> Second extended fs support
DOS/FAT/NT Filesystems
< > MSDOS fs support
< > VFAT (Windows-95) fs support
< > NTFS file system support
[*] Advanced partition selection
[*] PC BIOS (MSDOS partition tables) support
I've already tested this configuration:

<*> Second extended fs support
DOS/FAT/NT Filesystems
<*> MSDOS fs support
<*> VFAT (Windows-95) fs support
< > NTFS file system support
[] Advanced partition selection

My CF card has the following structure:

Disco /dev/sdc: 521 MB, 521773056 bytes
16 cabezas, 63 sectores/pistas, 1011 cilindros
Unidades = cilindros de 1008 * 512 = 516096 bytes
Disk identifier: 0x00000000

Disposit. Inicio    Comienzo      Fin      Bloques  Id  Sistema
/dev/sdc1               1         400      201568+   6  FAT16
/dev/sdc2             401         500       50400   82  Linux swap / Solaris
/dev/sdc3             501        1011      257544   83  Linux

I'm also wondering if I should use xsysace or xsa, because I have search in the file xsysace.c for the name of the device and It is named as xsysace. Am I right, and should I use xsysace? Or this name isn't related with the /dev file??

$ grep xsysace xsysace.c

        .name = "xsysace",
        ace_major = register_blkdev(ace_major, "xsysace");
                printk(KERN_WARNING "xsysace: register_blkdev() failed\n");
        unregister_blkdev(ace_major, "xsysace");

I'm going to reformat my CF card and test it,maybe the partition table is corrupted, but fdisk is not saying anything at all.

Thanks

You're definitely not having a filesystem problem; it's a partition table problem. Either the partition table is corrupt or the kernel doesn't understand the type of partition table, or the system ace isn't able to read the CF correctly (hardware problem).
