LS2085AQDS: ubi attach issue

Question asked by jiten patel on Jun 30, 2016

I am trying to boot LS2085AQDS board from NAND flash. I want to use ubifs file system. Now when booting from Nand, it boots well until the point of "mounting UBIFS" .

I referred the thread T1040RDB Failed to mount UBIFS | NXP Community  and tried to follow procedures but faced issue while attaching ubi with mtd partiton.

Here are my logs:-

 

ubiformat /dev/mtd9

ubiformat: mtd9 (nand), size 41943040 bytes (40.0 MiB), 320 eraseblocks of 131072 bytes (128.0 KiB), min. I/O size 2048 bytes

libscan: scanning eraseblock 319 -- 100 % complete 

ubiformat: 320 eraseblocks have valid erase counter, mean value is 1

ubiformat: flashing eraseblock 124 -- 100 % complete 

ubiformat: formatting eraseblock 319 -- 100 % complete

 

ubiattach /dev/ubi_ctrl -m 9

ubiattach: UBI_IOCATT: Invalid argument

 

Is the anything else i am missing for nand configuration or it could be some other issue? Have anyone tried ubifs filesystem on LS2085AQDS
