I have created bsp for devkit 8000 by cloning the bsp provided by company.I have created an application that reads and writes data on the serial port.For perfoming read and write operation I have addded serial port control provided by VS 2005.But I can get the port names of all the four ports and I can not perform read write operation.

    Can you please provide us with some details to help us understand what your issue is:

    - BSP version that you cloned for your hardware and CPU ref used

    - How far from the referenced EVM board your design is

    - Software used to validate the serial ports on the development PC

    I am using EVM3530.I have created application in VS 2005 and added a control serial port in it.This control shows me three com ports com1,com2 and com3.I can not perform read and write operation over it.

    I consulted electronics engineer, and he pointed that the clock is not working.As per the datasheet the clock should work for performing read and write operation.In the bsp where do I activate clock ?

    For power management purposes, clocks are only activated when you open the COM port, which is done from your application by calling the "CreateFile" function on the serial port you want to communicate through (i.e. "COM1:").

    Refer to PLATFORM\EVM_OMAP3530\SRC\test\testSerial in the unified BSP for sample usage of serial ports under Windows CE 6.0.
