6.2 The Manufacturing Tool, MFGTool
One way to place an image on a device is to use the Manufacturing Tool, MFGTool. The recipes used to build a
manufacturing tool image are linux-imx-mfgtool and u-boot-mfgtool.
To build a manufacturing image do the following -
$ bitbake fsl-image-mfgtool-initramfs
A manufacturing tool kernel is built using the imx_v7_mfg_defconfig while the default kernel is built by using the
imx_v7_defconfig. This is handled automatically by the MFGTool recipes listed above.
For more details on how to use the manufacturing tool, see Section "How to Enter Serial Download Mode for MFGTool" in
the i.MX Linux User's Guide.
