I agree that it is not obvious from the help output, but the fact that the chpart command is implemented in the cmd/mtdparts.c source file gives a clear hint: it works only for MTD devices, not for general storage devides using DOS (or GPT) partitions. > => mmc dev 0 > switch to partitions #0, OK > mmc0 is current device This is what you should look for. THe help output shoud tell you: ... mmc dev [dev] [part] - show or set current mmc device [partition] ... So instead of > => chpart mmc0:2 > Device nand0 not found! you would use: => mmc dev 0 2 Hope this helps.
