Hi,
I tried to use the UART pins in order to connect a USB-UART cable, following the pinout I found here:
However I don’t see any output on the UART port, either from U-Boot or the firmware. I’ve tried using several USB-UART cables, changed all the UART settings I could think of (and used the ones listed here), but to no avail.
Is there a setting to change in the U-Boot (version U-Boot 2022.07-rc3 (Mar 09 2023 - 16:20:34 +0800)) or the firmware (version 4.3.5) in order to enable the UART port?
