uartx01 example

[Tiago Vasconcelos]

Hello, the example with the uart that use PL011 seems not to work. Anyone else got a problem with this?

I know this is a couple months old, but I had trouble with both the uart01 and uartx01. For uartx01, I found that setting the following in my sdcard's config.txt helped:

init_uart_baud=115200
init_uart_clock=3000000

This is documented as the default here but for some reason setting them explicitly helped me (I was getting garbage output before).
