UART communication problem

cuckoo933

I received ROC-RK3588S-PC SBC today ^^.
I'd like to see booting log by UART but the text was strange to read.
I think there was no problem at terminal settings.
Please teach me what was wrong.

Maybe my USB to UART cable doesn't support 1.5Mbps baudrate...
If so, how can I change the default baudrate to under 1Mbps ?

As expected it seems my old cable doesn't support 1.5Mbps baudrate.
I bought new USB to UART module which using FT232RL chipset then it captured well the booting log at 1.5Mbps baudrate.

Basically yes.
But I'd like to know that is it possible to change the default baudrate ?
I would also like to know how to do it if possible.

Where can I find the rk3588_sdk.... ?
My SBC has updated from android to the ubuntu image.
And how can I get the ubuntu source code for ROC-RK3588S-PC ?
