[meta-freescale] [PATCH 3/5] imx7ulpevk.conf: Create i.MX 7ULP EVK machine configure file

[Jun Zhu]

Hi, Fabio,

The M4 images not buily by Yocto, they are pre-built by the M4 SDK tool-chain. The source code for these images are in the 7ulp M4 SDK.
 
And these binaries are packaged into "imx-m4-demos-7ulp-beta.bin" and would be deployed to the boot partition along with Kernel and DTB files by "bitbake imx-m4-demos".

Enter u-boot command line mode, the user can make these M4 images run on M4 core directly.  

BR,
Jun Zhu

Just for my understanding: where are these M4 images coming from? Are they built by Yocto and by IAR tools in Windows?

Please clarify.
