Does anyone know how to restore the blocks? All the OOB data are zeroed out. goog long wrote: I have the same problem. I enable YAFFS_TRACE_ALLOCATE, YAFFS_TRACE_GC and YAFFS_TRACE_GC_DETAIL this time. I also capture /proc/yaffs before and after copying file. There are already some bad blocks marked by the last run. It is noticed that there is a soft lockup in the middle.

The garbage collection is done automatically by yaffgs as a by-product of any operation that modifies the file system. It seems to me that one of two things has happened here: 1) Garbage collection triggering is broken somehow, so yaffs does not triger garbage collection. 2) The garbage collection is failing because the erasure is failing or some simil;ar problem. Thsi means that attempts to do garbage collection do not free up any space. Try turning on tracing for YAFFS_TRACE_ALLOCATE, YAFFS_TRACE_GC and YAFFS_TRACE_GC_DETAIL. These should give a far better indication of what is happening. > > Regards > Paul > ----- Original Message ----- > From: "Charles Manning" > To: > Cc: "Paul Wang" ; ; > ; ; Sent: Tuesday, > October 24, 2006 8:23 AM > Subject: Re: [Yaffs] yaffs problem: !!!!!!!!!
