Linux/66AK2G02: K2g support uart1 and uart2

Part Number:66AK2G02

Tool/software: Linux

Hi,

TI,

I am working on the SDK04.01 of k2g,and I want to make the uart1 and uart2 work on the linux-4.9.41.

I modify the kernel like that:

Now the uart1 not work fine at the baud rate 115200bps,but it is ok at 9600bps.The uart2 is ok at 115200bps and 9600bps. Use "echo "23423e23e2" > /dev/ttyS1" or "echo "23423e23e2" > /dev/ttyS2"

 to test.If I use "getty 115200 /dev/ttyS1" or "getty 115200 /dev/ttyS2",the console of uart1  and uart2 do not display any char.

any solution?

BR,
