Other Parts Discussed in Thread: OMAP-L138

Hi all,

in our project(using omap-l138 wince6.0) , three serial port is needed , so all three serial port is selected in the ThreePart\BSP catalogs in vs2005.

But error happened  , after running NK.bin on out platform , and running "uarttest -d COM3:" ,  The error message is "ERROR: Failed to open COM3:  (error 55) " .

While All is OK , if running "uarttest -d COM1:" and "uarttest -d COM2: "

Why this happened.

    Hello Arthur

    On which hardware platform did you try the uarttest?  I believe the uarttest should fail on COM1 (UART0) and COM2 (UART1) on the LogicPD OMAP-L138 EVM because the two com ports are not exposed.  The exposed serial port is COM3 (UART2) which by default is the debug serial port.

    Also could you tell us which OSDesign from which release did you use for your build?  Any additional changes in the OSDesign?

    Regards
