Hello,

This error is seen because the type-C IC, is either not found or have an incorrect slave address in your custom board.
On the USB side, how different is your design from our EVK?

Best regards,
Aldo.

Hi,

Please disable Type-C (TCPC) config in your uboot defconfig, for example I our defconfig this enabled by dafult:

https://source.codeaurora.org/external/imx/uboot-imx/tree/configs/imx8mp_evk_defconfig?h=lf_v2020.04#n127

Change it to:

CONFIG_USB_TCPC=n

Best regards,
Aldo.
