Hi All,
I am very new to mtd & yaffs and working on boottime optimization and found that yaffs checkpointing helps to mount yaffs2 very quickly. I tried it, and was able to save almost 4sec for 128MB partitioned nand.
Since everything looks very good If I use yaffs checkpointing feature but have a doubt, are there any disadvantage of using check-pointing by default in final product?
I understood that, check-pointing only disables boot time nand block scanning & marking it bad if found, and takes "system snapshot" while using "umount /dev/mtdblockN" which it use in next boot. So, If I decided to use "checkpointing" with "umount" while powering off the device in final product, are there going to be any problems I will face avoiding block scanning?
Thanks lot for any help.
Thanks and Regards, Shivdas Gujare
