Crash while using WriteFile()

Hello together,

do you know if there is a problem with the WriteFile() to serial interface (COM2:) method?
Used kernel: Build date 15 May 2014

I have following problem:
When I use this method extensively, sometimes my complete board freezes because the WriteFile() method does not return any more - it still hangs. Sometimes this happens after a few minutes, sometimes after some hours and sometimes not on a day.

Now I have tested this with a timer all 20ms sending a string of approx. 30 chars to COM2: and after max. 30min the board freezes - most times much earlier.

At the moment I'm testing it on an older NetDCU6 board and for the moment it looks ok. I will report if there are some changes.

Best regards, Kaiser

Hello,

sorry for delay. I have been out of office and now back.
Thanks for that quick response.
At the moment I'm testing and will report as soon as possible...

Best regards, Kaiser

Hello,

Software works fine now. All customers report no problems any more. Thank you.
Just one question. Could you create the same version with a different date on desktop / in debug of bootloader?
At the moment I can't distinguish between old and this beta.
Thanks a lot.

Best regards, Kaiser
