I have a problem : when my kernel mount the rootfs (yaffs 1 ),there are many yaffs ecc error: [42949455.170000] **>>yaffs ecc error unfixed on chunk 1741:0 [42949455.180000] **>>yaffs ecc error unfixed on chunk 1741:1 [42949455.180000] **>>Block 54 marked for retirement [42949455.190000] **>>yaffs ecc error unfixed on chunk 1742:0 [42949455.190000] **>>yaffs ecc error unfixed on chunk 1742:1 [42949455.200000 ] **>>Block 54 marked for retirement [42949455.200000] **>>yaffs ecc error unfixed on chunk 1743:0 [42949455.210000] **>>yaffs ecc error unfixed on chunk 1743:1 [42949455.210000] **>>Block 54 marked for retirement [42949455.220000] **>>yaffs ecc error unfixed on chunk 1744:0 [42949455.230000] **>>Block 54 marked for retirement [42949455.230000] **>>yaffs ecc error unfixed on chunk 1745:0 [42949455.240000 ] **>>yaffs ecc error unfixed on chunk 1745:1 [42949455.240000] **>>Block 54 marked for retirement ..................... this error message is printed by yaffs_ReadChunkFromNAND(yaffs_tagscompat.c) ,yaffs_Scan call this function. I mount the root as yaffs ( my flash chip is 512B page ,kernel 2.6.12 ,yaffs2 source ), so I think whether yaffs1 tag compatible with the yaffs2 cource I use?   _______________________________________________         ÃÀ Å® ¿Ö ²À °Ü ¼Ò Ðã ( ×é ͼ ) . http://adtaobao.allyes.com/main/adfclick?db=adtaobao&bid=600,597,58&cid=29985,198,1&sid=32501&show=ignore&url=http://www.taobao.com/vertical/lady/body_12.php ¶À ¼Ò Åû ¶ !
