Hello!

There is a problem when the func uffs_BufFlush_Exist_With_BlockCover() is called. The debug Informations are as follows:

pbuf: the old block 301 is a bad block, but ignore it for now.

pbuf: the old block 302 is a bad block, but ignore it for now.

...................

pbuf: can't load page from flash ! fs : can't get buffer when read obj.

I found this problem is happend when func uffs_BufLoadPhyData() is called, and func uffs_FlashReadPage() returns an error.

I tested more than 2000 devices, and The problem was found in 8 devices.

Ricky, can you help me why this problem happend? What should I do to fix this problem?

The uffs's version is uffs-1.3.5, and uses UFFS_ECC_SOFT.

My config.h is as follows:

#define UFFS_MAX_PAGE_SIZE 2048

#define UFFS_MAX_SPARE_SIZE ((UFFS_MAX_PAGE_SIZE / 256) * 8)

#define UFFS_MAX_ECC_SIZE ((UFFS_MAX_PAGE_SIZE / 256) * 5)
