Hi,

I've successed config UART1( dts statue=ok ) to work at 115200.

Now I need 460800,I tried to use :

cfsetispeed(&newtio, B460800)

config the baudrate to 460800.But I got wrong data through UART.

Hello,
there are some steps that can be performed to debug the issue
- after setting the new baud rate add some delay and read back the setting with cfgetispeed()
- try 230400 to see if the issue persist
- set both output and input baud rates to same speed
I'm suggesting just simple actions to triage the problem. Although it can be more deep issue including hardware design.

Hello,
since I have no answer from you I assume you resolved your problem.
You can reopen it if there is still an issue.
