Is there a simple way to check DMA buffer overflow in Auto DMA mode?

There may be a possibility calling CyU3PDmaChannelGetStatus() and then comparing prodXferCount vs consXferCount.

 

However, I am wondering if there is a better solution, like some flag that is set once a DMA buffer overun occurs.

Hi,

You can use "CY_U3P_DMA_TYPE_AUTO_SIGNAL" to get the notification of the events.

For more details, please refer to "USBBulkLoopAutoSignal" example project.

Thanks,

sai krishna.
