What is the firmware that you are using here?
Is it any example firmware or custom firmware? If it is example, what is the project?
How much data you are sending over Bulk Out Ep?
Thank you for your time and response .
We are using slaveFIFO firmware.
It is example firmware project that is, slavefifo .
We are send 11 bytes of data at a time.
Thanks and Best Regards
In the SlaveFifo example project, only two DMA buffers are allocated for USB_OUT-> PIB_SOCKET_3.
When DMA_CB_PROD_EVENT is generated; In the CyFxSlFifoUtoPDmaCallback() function, the DMA buffer is committed to the consumer PIB socket. Unless the two DMA buffers are read and emptied by the FPGA, you cannot write any more data. Please make sure you are asserting SLRD# and reading the data from FX3.
