Hello, The minimum blocks for YAFFAS is 9 blocks. If I change 'dev->nRservedBlocks = 5' to 'dev->nReservedBlocks = 4' in the yaffs_internal_read_super function, what could be the side affect? Do I need to change any other code if I change nReservedBlocks as 4? I need to have two YAFFS partitions: one size is 128K (8 blocks) and the other size is 64MB. Thanks, Chung
