xmodem application failure on VDSP5.0++

Hi,

 

I have a xmodem application that has been working perfectly with VDSP4.5++. But for some reason it doesn't work at all with VDSP5.0 although the application codes are kept exactly the same.

 

Just for more information, what this xmodem application does is to use XMODEM-1K of the Hyperterminal to transfer a file from my computer to the SDRAM of BF537. From the unser interface of the hyperterminal, I saw the message "unrequested response" very close to the beginning of the transfer. And then, the transfer simply went to crash (due to too many retries).

 

I'm wondering what could possible the reason to have caused this.

 

Your expertise and help will be sincerely appreciated.

 

Thanks in advance.

 

Sandra
