We would like to increase the standard speed of the Xavier AGX debug UART which is initialized by MB1… we want to run the UART speed above 115200. We want to be able to boot quickly with the faster UART enabled and want to be able to use the faster UART speed when we are booted all the way into the Xavier kernel.
Ideally the speed would be around 1 megabaud, like 921600 or 460800. We are using Jetpack 4.4.1
Can this be done through some MB1 configuration file or similar? We want to see the entire boot sequence for MB1+MB2+cboot+kernel… just at high speed instead of 115200. The quality of the wires should not be an issue because the wiring is on a PCBA from Xavier to another chip and is shielded properly.
