I am using the BF 548 Ez kit Eval Board.


for my application, i need 2 UART's working togather. not secessery at the same time.

I have connected and configed UART3 TX and RX and its working good.


Then i have connected UART1 (Expension connection) TX and RX. TX is working while RX cannot get "receive interrupts".

There is no problem with the Sender, because UART3 RX can get msg from the Sender.


I have attached my startup code, but basically the configuration shouldn't be much different.


How can i define the system to work with 2 UART interrupts?
