Integration

There are two options to integrate the MFG package into your system:

Manually install the MFG package:

Once you get the MFG package, decompress the package:
```
tar jxvf mfg611-aarch64-13.24.0.20.tar.bz2
```
Run mfg611-aarch64-13.24.0.20.sh install, which will install the MFG tools and firmware into your host platform.
Build into image by yocto recipe:

To build the MFG package into your image, you’ll need to add the following into your recipe:
```
IMAGE_INSTALL:append = “summit-mfg611"
```
Then create a folder named release under ${BSPDIR}, and copy the MFG package mfg611-aarch64-13.24.0.20.tar.bz2 into this folder.

lmu_611

After you integrate the MFG package, you can find a tool called lmu_611 under the /use/bin folder in your host platform.

After you execute lmu_611, the following will be displayed:
