Hi,
Regarding the partial page write programming, I do not believe it is
possible because the write cannot take place in-place on disk. YAFFS2 can
write each chunk only once on disk before the whole block gets erased. You
can only write in-place as long as the chunk is in main memory. For small
writes the efficiency of data storage will be low, I believe.

Since the rainfall information collected each time is only 20 bytes, yaffs file system usually applies the ‘out of place’ strategy. I don’t think this is quite an efficient way. So how about adding ‘partial page programming’ into yaffs which directly stores new data following the original without assigning new chunk while small data file is being written.
