Hi community,

I'm working on i.MX6 sabresd Quad platform with no pmic and using Android as my OS system.

Because of this reason, I need to build a new firmware image for my platform.

change u-boot-imx6qsabre_sd.imx

未命名.png

I used Yocto Project to build uboort firmware for platform.

First, I run "bitbake u-boot-mfgtool" then start to modify new uboot firmware.

But now I got several questions here.

Question:

  1. Which defconfig do I need to use? mx6qsabresdandroid_defconfig or mx6qsabresd_defconfig?
  2. I need to modify uboot driver for my platform (No PMIC), what should I be noticed when I designed it?

Hi tsung

as described in sect.6.2 Manufacturing Tool, MFGTool attached Yocto

Guide, imx_v7_mfg_defconfig should be used.

If there is no pmic, it is necessary to remove all pmic references in uboot

and Linux, drivers using pmic are described in Chapter 21-24 Linux Manual.

Best regards
igor
