Hi Xiaoguang,
I tried setting CONFIG_YAFFS_DISABLE_TAGS_ECC, compiled and used the
kernel.
I'm getting the same results. When I do "touch" to create a file on the
partition I still get "cannot allocate memory" and I
see the partition's free space decreasing until there is no more. In the
kernel log I can see yaffs retiring all blocks...
