We have a custom carrier board with a Xavier NX production module. Since we needed more UARTs, we used the debug UART (uartc) as a UART and disabled the debug UART through modification of p3668.conf.common, tegra194-p3668-common.dtsi, tegra194-mb1-bct-misc-l4t.cfg, tegra194-mb1-soft-fuses-l4t.cfg an…

[image] dan.madill: This is good. Now I just have to figure out why trying the same thing in the device-tree source files didn’t work the same way. It’s great to hear this. Because bootloader(UEFI) and kernel use the same device tree file, it seems disabling combined-uart for UEFI may cause …
