Hello Huang, Can you please explain what is the exact difference between the NAND layout when using JFFS2 in FSL 2.6.35 and in mainline with your patches ? Is there any way to mount JFFS2 written with FSL 2.6.35 on current mainline? Thus far, neither me nor Hector were able to mount such partition with the same result. Best regards, Marek Vasut
