Hi,

u-boot version: U-Boot 2021.07-rc1 Board: Beaglebone Black

I was trying to verify and use 'chpart' command on Beaglebone black with an SDHC card ( with multiple partitions ) and am unable to get its exact syntax.Is this command applicable to any particular category of storage devices (viz. NOR flash,NAND flash etc)?? I tried using it as in its "help output" and also other combinations, Am I missing anything,Please suggest its correct usage.

Usage: chpart part-id - change active partition (e.g. part-id = nand0,1) => => chpart part-id=mmc0 Device nand0 not found! => chpart part-id=mmc1 Device nand0 not found! => chpart part-id = mmc1 chpart - change active partition
