As you are talking about partitions, I assume you refert to the MTD partitioning. In this case the bad block handling needs to be done in by the file system code, when you create a file system insinde one of the partitions. [Note that this differs from UBI, where bad block handling is done for the whole device, independent of the volumes that you create on top of it.] Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd at denx.de When you die, the first thing you lose is your life.
