Use not standard baud (10400) on am335x

user4121072

Dear All,

We are working on AM335X with Linux 3.2.0. Normally, we use the UART baud rate 9600, 14400, 19200, etc..

But some of our customers want to use the baud rate 10400. But when I set baud rate as 10400 in my program, I can not get the 10400 baud rate from UART, it is 9600.

I want to know the 10400 is an available baud rate in am335x？ If yes, how to setup in my C program?

Can you provide some help?

Thanks in advance,

Dear All,

I fixed my issue by adding the below code in serial_omap_get_divisor of omap-serial.c
if (port->line == 1) {
return 288;
}

288 was got by 30000 divide 10400.
it is work but I don't think this is optimal, anyone have a batter way?

Best Regards,
Jakebo
