Hello,all<br>&nbsp;&nbsp; I&#39;m using yaffs2 on Linux 2.6.20, our hardware supports Reed-Solomon ECC Accelerator.<br>the HWECC generates 9-bytes of parity code for each 512 Bytes of data. So , in a 2K page,<br>the ECC parity code will take 36 bytes, and there&#39;re only 28 bytes left for Yaffs2.
<br>I found that yaffs2 need 32 bytes of Spare space, is that possible yaffs2 use less than 32 bytes? or <br>I need to give up using HWECC...<br><br>Thanks!<br clear="all"><br>-- <br>Best Regards!<br><br>He Yong<br><br>School of Information Security,
