define CONFIG_MFG_ENV_SETTINGS \
"mfgtool_args=setenv bootargs console=${console},${baudrate} " \
CONFIG_BOOTARGS_CMA_SIZE \
"rdinit=/linuxrc " \
"g_mass_storage.stall=0 g_mass_storage.removable=1 " \

Hi Ankit

actually mfg tools firmware is linux with root file system in ram

fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot

Build steps are described in attached Yocto Guide sect.6.2 Manufacturing Tool, MFGTool

Hi Igor,

thanks i tried exercise of yocto pdf section 6.2.

in the log it is still hanging at the

"UTP: Waiting for device to appear
UTP: file/device node /dev/utp already exists
cpu_id is 0"

linux-kernel is not booting completely.

any solution for this.
