Correct. > 2) I will also get an added block or two to use for data, right? Correct. Exactly how much space checkpointing uses depends on the size of your filesystem. > 3) How can I disable checkpointing? You could originally do this (quoting Charles:) by setting the checkpoint and main areas to overlap. eg: dev->checkpointStartBlock = 0; dev->checkpointEndBlock = 0; dev->startBlock = 0; dev->endBlock = nBlocks - 1; However then it got updated to chop of a chunk by itself for use. So now you set nCheckpointReservedBlocks to 0 for the yaffs device in question.
