Hi NIKHITHAANTONY,
There are 2 mfgtools, the mfgtool v2 and the Universal update utility (UUU).
For the mfgtool v2:
Manufacturing Tool V2
For UUU you can find more info on the documention that comes on the BSP:
IMX_LINUX_USERS_GUIDE
Personally I prefer the UUU tool but the one you would like to use is up to you.
Regards,
Israel.
