Hello !


I program  UART  of ADSP BF548 EZ-KIT  ,and meet some problems


first I use the UART driver example in the VDSP

It run correctly.


but When I change the UART_DEVICE_NUMBER from "1" to "3"

then build all and run ,  It's said that Failed to Open the UART.


BF548 have 4 UARTS,  I can open UART0 and UART1, while  I can't open UART3,(neither UART2)

I don't know what's wrong with it.

Could some one help me ? 

Thank you !
