Hi all,

After doing factory reset (erase all data) under Android, reboot the mek. USB debug port can't work. Is there any one meet this kind of issue ? 

I don't know how to recover it, and I want to change debug port from debug usb port to RS232 port on base board.

Is there any one know how to change debug port from debug-USB to RS232 port ?

Thanks

Jack

Hi Jack

one can try to reflash image with Demo Images – i.MX 8QXPlus MEK and Tool on the link
Alpha / Beta BSPs for Microprocessors|NXP 

Note i.MX8QXP is not publicly released yet and so not fully supported,

in general uart port initialization codes can be found on

uboot/board/freescale/imx8qxp_mek/imx8qxp_mek.c

https://source.codeaurora.org/external/imx/uboot-imx/tree/board/freescale/imx8qxp_mek/imx8qxp_mek.c?...

Best regards
