IMX8MQ minimum system compilation (chip model: MIMX8MQ6DVAJZAB)

[ximenbingmeng]

a. We see that the official compilation method for NXP is yocto, so why did the supplier give us uboot kernel、 Is the file system compiled separately through scripts? How is the minimum system implemented? b. If you need to compile a file system, does it have to be done through yocto? c. We are using version 4.14.98, how can we quickly upgrade to version 6.6.3?

There are documentation of BSP. You could download the documents from here:

You could follow the steps in Yocto User's Guide to build the BSP. The u-boot, kernel and the rootfs will be built by Yocto and the images will be in the deploy folder after building success.

For the details about how to porting your custom board to the BSP, please read the i.MX Porting Guide.
