[Ltib] Cannot boot rootfs from SD card LPC 3131

[Gianluca Valentino]

Dear All,

I wish to boot Linux on my LPC 3131 in the following manner:

startup = copy ext2://1/zImage 0x30008000; boot
cmdline console=/dev/ttyS0,115200n8 root=/dev/mmcblk0p1 rw rootfstype=ext2

However I get the following:

VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "mmcblk0p1" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partitions:

1f01 4096 mtdblock1 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

Don't worry about the RAMDISK IMAGE too big part, that's because I used a rootfs of > 64MB, for smaller rootfs.ext2 it still gives me the same errors at the end.

Could you please help me out?

Thanks and regards,

Gianluca Valentino
