I set dtparam=uart0_clkrate=64000000 in config.txt. I see it in dmesg But when I try to speed up UART, stty -F /dev/t...

Raspberry Pi model 2 B Uart max speed

Hi,

I have got a problem with the pi model 2 B.
I can't change the speed to 1 Mbaud.
With the old model, it was possible with a command in config.txt
init_uart_clock=16000000

But now, this command don't run.
I try many other command( dtparam...) but no solution yet.
Do you have any idea ?

Regards,
