Hi community,

I'm working on the i.MX6 sabresd Quad platform with no PMIC.

 

While I try to burn image with mfgtool and I received log that show no pmic detected.

 

So I assumed that I need to build new uboot and kernel for mfgtool.

 

I had set the environment for Yocto project and try to build uboot image and kernel image with "bitbake linux-imx-mfgtool" and "bitbake u-boot-mfgtool" .

 

But I do not know where can I modify uboot code to avoid detecting pmic.

 

Question:

  1. Is there any document show how to build customize uboot and kernel for mkfgtool firmware?
  2. Is u-boot folder shared with both mfgtool firmware and image of my board?
