u-boot serial port speed?

[zener]

I recently got a RockPro64 and I'm assuming it's using u-boot. I have a USB serial port adapter attached to my board and I can log in at 115200.

However, when I power cycle the board I see that it's outputting something with different serial port parameters. What are the serial port settings to be able to interact with u-boot? And what is the command sequence to get into the u-boot command line?


Thanks!

Wow, I tried 115200 and down to 9600. 1500000 works great. Thanks!
