Dear technical support:
    I received the i.mx8QuadxPlus development board, how to compile the emmc firmware downloaded based on UUU in yocto configuration
   I am developing based on imx-yocto-L5.4.47_2.2.0,
   I configure local.conf: UBOOT_CONFIG = "emmc" and imx8qxpmek.conf: UBOOT_CONFIG ?? = "emmc",
  but they have no effect. How to configure and compile correctly What?
  Thank you！

Hi 783435100

uboot configurations are described in sect.5.5 U-Boot configuration

i.MX Yocto Project User’s Guide​

seems one can use the same configuration as for sd.
