Hello,

is it possible to customize kernel to activate an additionnal uart on XU4 as it seems to be possible for C0 based on :

No. there is no exposed additional UART pins from the SoC Samsung Exynos-5422.

The extra UART port was available on the Amlogic SoC only.

Alternatively, you can use the Rx/Tx pins on the 4pin console port as a generic UART pins.
