So in YAFFS2, Variable Chunk ID has been lifted up to 32 bits. That limits any particular file to <span style="color: rgb(255, 0, 0);">2^43</span> (assuming 2048-byte<br><div class="gmail_quote">
chunks). And this is ultimate theoritical maximum file system size YAFFS2 can recognize in one partition? Is there any other limit? <br><br><div class="gmail_quote">2008/10/30 Charles Manning <span dir="ltr">&lt;<a href="mailto:manningc2@actrix.gen.nz" target="_blank">manningc2@actrix.gen.nz</a>&gt;</span><div>

&gt; In yaffs_guts.h, YAFFS_MAX_CHUNK_ID is 0x000FFFFF.<br>
&gt; If my nand flash page size is 2048 bytes, it means that the max nand size<br>

&gt; Am I right?<br>

That chunk Id refers to the chunk Id in a file (ie offset of chunk numbers<br>
into a file).<br>
<br>
That limits any one file to approx 2GB with 2048-byte chunks.<br>
<br>
This limit can be reasonably easily lifted to cope with larger files.<br>
