The example of “uartEcho_edma” using uart0 in starterware worked properly.
When I use uart2 instead of uart0，it does work properly.
But when I use uart4 instead of uart0，it does not work properly.There seems no data received.
The changes of the code from uart0 to another uart:
UART0ModuleClkConfig to UART0_4ModuleClkConfig
the parameter of UARTPinMuxSetup
My English is terrible,I am sorry。
Where is the problem，can anybody help me?
Lei, Please take a look at this application note. Its not specific to the uartEcho_edma example, but will give an idea on what changes are needed in the code. Hope this helps. http://www.ti.com/lit/an/sprac32/sprac32.pdf Lali

Thank you for your response.
The example of “uartEcho” using uart4 in starterware also worked properly.
The changes of example “uartEcho” from uart0 to uart4:
SOC_UART_0_REGS to SOC_UART_4_REGS
That is to say,the two function UARTPinMuxSetup(4) and UART0_4ModuleClkConfig() worked well in example uartEcho.This two function seems correct.
But with addition changes of only some macro definitions metioned above,the example uartEcho_edma does not work.
