ar6k_wlan issue

[pankajjoshi]

Hi All,

I am using mfgtool to partition and flash my image. In the process. I migrated from one partition to 3 larger partitions. Now it seems the emmc is not being erased completely, so i get wlan driver failures. In the begining of bad boot up i see readonly fs on my primary partition and then later when the wlan driver probing emmc, it fails to load.

Below are the logs,

EXT4-fs (mmcblk1p1): INFO: recovery required on readonly filesystem
EXT4-fs (mmcblk1p1): write access will be enabled during recovery
EXT4-fs (mmcblk1p1): recovery complete
EXT4-fs (mmcblk1p1): mounted filesystem with ordered data mode. Opts: (null)
