VDK UART overrun error

Hello,

 

i am using the BF537 evaluation Board and I have a problem with the vdk device drivers. I've programmed a UART module to communicate with an other card. The transmiting of data is no problem. The other card receives the string correctly. But if the other card transmits a string back the the event of the callback functions points to overrun error.

 

Also strange is that when the other card sends only a character the Blackfin doesn't create a callback, but when the other card sends two character "AB" the blackfin creates two callbacks with overrun error and the receive buffer is filled with the last character "B".

 

 

Thank you!

Regards,

David
