hi,all,
Maybe this question is easy,but I just confused. I use my nand chip as a mtd block device.now I open mtdblock by using the "open()" function. and I want to read the OOB part by use the mtdblock device.now I want to know if I could read the OOB by operating an mtd block device or only I use the mtd char device could I solve this problem .Thanks!~

Use the char device to read and write the OOB.
