Changing default buadrate

Hello all,

How would one (if at all) change the default baud rate of the ROC-RK3328-CC board from it’s default of 1,500,000 to 115,200?

I am aware that the documentation states to get a USB to uart connector that can deal with the 1,500,000 baudrate, however I already had a connector around and do not want to wait for getting another one.

I think this is the issue that is stopping me from connecting the UART to my computer.

Any guidance is much appreciated.

Thanks

UART baud rates are set by whatever application is utilizing it. If you are talking about the Linux kernel logs, you need to set the baud rate in GRUB. If you are referring to low level baud rate in the bootloader, that cannot be changed unless you compile your own custom atf/u-boot.
