CONFIG_JFFS2_CMDLINE should add mtdparts command. Please double check where you add this option and ensure that it is not added in some #ifdef ... #elif ... #endif construct. Depending on the CFG_USE_* build options some options in the config file may have no effect at all. > But the command is not available on my system. > Would it help to post my .h or maybe my build log?
