Hi,

we are working on imx8qxp based reference design with yocto distro 4.14 sumo. Our yocto Linux image is working fine with that.
we want to migrate yocto distro 4.14 sumo to 4.19 thud. We have taken the imx8qxp-mek evaluation board as the reference.
Our pmic is same as mek evaluation board.
For migrating distro, we made some modification in uboot like some gpio and change UART in UART 0 to UART 2.In our custom design UART2 work as debug UART. But we didn't see any print on our debug console.
Please help us to resolve this issuse ASAP.
I have attached my uboot patch for your information. Please let me know if you need further information.
Thanks,
Saurav
