Hi,

 

    I am using bf548 EZLite kit. While running my application, I'm getting message "sport status error: TUVF". After displaying this message application stops playing sound for some time(2 0r 3 minutes ) and then it starts playing sound.

 

    Can u plz tell me what are the causes for it? How can I avoid it??

 

Thanks,

 

Maha

Underflow. You're not giving it enough data.

 

But your question is hideously vague.    Like... "I'm driving a car.  It stopped.  Why?" 

 

I think you need to describe a lot more detail if you want real help.

 

Load the datasheet.  Enter "TUVF".  It gives you some info.  Did you even try this basic self help?

 

"When DITFS = 1, the internally generated TFS is output at its programmed interval regardless of whether new data is available in the SPORTx_TX buffer. Whatever data is present in SPORTx_TX is transmitted again with each assertion of TFS. The TUVF (transmit underflow status) bit in the SPORTx_STAT register is set when this occurs and old data is retransmitted. The TUVF status bit is also set if the SPORTx_TX buffer does not have new data when an externally generated TFS occurs. Note that in this mode of operation, data is transmitted only at specified times."

when asking questions, you need to fully describe your setup.  what version of software (toolchain/kernel/etc...) ?  what audio device exactly are you using ?
