imx8mmevk android flashing

Hi Team

I am trying to flash android on already loaded yocto linux imx8mmevk.

When I try to run the command ./uuu_imx_android_flash.sh -f imx8mm, it repeatedly loops in flashing u-boot.imx

and on the debug console I am getting this error:

Hello,

It seems that uboot is failing to initialize the type-C in the board, you can try removing from the defconfig and from the dts file those dependencies:

From defconfig:

CONFIG_USB_TCPC = n

fsl-imx8mm-evk.dts:

&usbotg1

{

--- drm_mode= "otg";

--- extcon = <0>, <&typec1_ptn5110>;

--- picophy,pre-emp-curr-control = <3>;

--- picophy,dc-vol-level-adjust = <7>;

status = "okay";

};

&usbotg2

{

--- drm_mode= "otg";

--- extcon = <0>, <&typec2_ptn5110>;

--- picophy,pre-emp-curr-control = <3>;

--- picophy,dc-vol-level-adjust = <7>;

status = "okay";

};

Hope this helps,

Regards,

Aldo.
