This job file shows how one can write sequentially to an MTD device, erase (with trim), and do a looped write/trim workload. Ignoring EIO errors allows operations to continue as bad blocks are skipped. The block histogram counts P/E cycles and can be used to assess NAND flash lifetime and failure characteristics. The job file is written to work with the nandsim fake NAND device.
