UART baud-rate problem in frdmk64

Hi,

i am using KSDK 1.1.0 example and KDS 2.0 IDE. am working on FRDMk64f120 controller.

i am trying to change 38400 baudrate. but am getting junk value. its working fine with other baudrate . and also am using all 5-UART.

UART-0 and UART-1 working fine with 38400. but 38400 baudrate not working with UART-2,UART-3,UART-4. its working fine with other baudrate .what could be the problem?

i am doing same baudrate configuration setting for All UART. i mentioned below,

UART_HAL_SetBaudRate (UART0_BASE,120000000U,38400 );

UART_HAL_SetBaudRate (UART1_BASE,120000000U,38400 );

UART_HAL_SetBaudRate (UART2_BASE,120000000U,38400 );

UART_HAL_SetBaudRate (UART3_BASE,120000000U,38400 );

UART_HAL_SetBaudRate (UART4_BASE,120000000U,38400 );

only problem 38400 baudrate. please give some solution.

regards,

hi,

i already wrote lot of Application code using KSDK1.1.0. so suddenly how can i switch to KSD1.3.0. because i used lot of library like tcp/ip ,flash ,DSPI. i cant change all my application code to KDK1.3.0. because its giving lot of error while switching to other version. is any other solution.

and also i have UART parity problem also. i tried to use

1)7E1 -7bit, even parity ,one stop bit

2)8N2

3)7E2 is not working

is all problem solved in KSDK1.3.0..? for this which KDS version KDS2.0 or KDS3.0 ? and also can you give solution for parity problem also. i already discussed parity problem with community person but still am struggling with this one.i am not get solution for this one.
