Hi,
I'm using Android devkit 3.0 with its 2.6.37 kernel on a DM3730 board (similar to Beagle-XM) which uses Micron MT29C4G48MAZAPAKQ-5) 256MB LPDDR/512MB NAND (same as used in beagleboard C5). I was running into problems with ubifs on this. ( http://permalink.gmane.org/gmane.linux.drivers.mtd/42868 )
So I started running the mtd tests. I found that most tests are passing but pagetest, oobtest, and subpagetest are failing. Does this mean I have hardware issues or is it possible I have errors in my configuration/setup or known issue in 2.6.37 ics kernel? I would appreciate any advice/suggestions.
Thanks,
jayakumar
