Create a new partition in emmc by uuu script Linux for flash yocto images

Dear NXP,

I have to create the 5 partition in EMMC using UUU script. Please provide the script or steps. Currently I am using following commands to flash,

.\uuu.exe -b emmc_all .\imx-boot .\ccu-rootfs-image-wabco_ccu.sdcard.bz2

partition "all" means whole device

Regards,

Hi Vinoth

one can look at sample scripts examples:

If mfg tool used before, look at sect.Migration from mfgtool ucl2.xml uuu manual

Best regards
igor
