Hi All,

I am using Attitude Adjustment falvour of OpenWRT.

I have compiled a OpenWRT firmware for my unit. When the unit boots I am getting following error message,

jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000: 0x0527 instead

switching to jffs2

Note: I have created the partition named "rootfs_data", but I guess it is not being formatted with jffs2 file system. Could any one please point where I am doing the mistake?

Any help would be highly  appreciated.

I don't think I know how to help you, but at least elaborate on what device you have (supported? applied some patch to official source?), how did you flash it, etc..

Thank you for your response.

I am using a arm based unit similar to Netgear WNDR3800. Flashed the firmware from boot loader prompt.
Most importantly, I have created the "rootfs_data" partition explicitly.
Is it necessary to have a specific flash layout to make "rootfs_data" work properly ?

Hi All,

Could any one provide any idea ??
