hi,I have write a app to test COM,
first i wirte a receive thread to waiting the WaitCommEvent return, at firist time i get EV_RXCHAR and can read 2 bytes data(data is right), when i send more data to my board on pc,my board can not return from WaitCommEvent.

But if i delete WaitCommEvent,and direct read the File hand as belown:

memset( recvBuf,0,124);
BOOL fReadState = ReadFile(m_hComm, recvBuf, 1024, &dwLength, NULL);
i can read the right data send from pc.

My question is The wince5.0 (download form at91 for atmel9260) usart dirver do not support this event or some thing wrong in my app,
thank you~

Hi,
I have the same problem, at first time I get EV_RXCHAR and can read a character from pc, but after that I can't catch any more event.
I try both 9260ek and 9263ek bsp(latest version), both have this problem.

Can anybody help me?
Thank you.

I have the same problem on at91sam9263.
It looks like that an interrupt is missed! This is caused by the DisableInt() function. DisableInt() completely(!!!) disables processor interrupts at lowest level (CPSR). In my opinion this is a horrible solution as this also might break the interrupt handling of the whole system.

Hi all,

The updates of the WinCE 6.0 BSP has priority over CE 5.0, so there is no update planned on WinCE 5.0 for the moment.

The serial driver of CE 6.0 has been improved and is more compatible with the win32 serial functions.
The easier way is that you back-port the WinCE 6.0 serial driver to CE 5.0.
The BSP has been modified and we pushed the new version to ATMEL but it seems that the web site has not been yet updated.

Please contact our sales service at sales.emea@adeneo-embedded.com to get the new version of the BSP for your target.
