TDA3: QSPI Event to trigger DMA Request in EDMA3 Controller

Part Number: TDA3

Hello,

The write speed of the QSPI interface is very slow, because the transfer is managed by the M4 CPU. To speed this up we are working on a transfer with chained EDMA instead of CPU.

The Transfer:

1. EDMA writes data to the QSPI interface (QSPI_SPI_DATA_REG)
2. EDMA triggers the transfer by writing to the QSPI interface (QSPI_SPI_CMD_REG)
3. QSPI interface issues a interrupt to IRQ_XBAR
4. The interrupt from QSPI should trigger the next EDMA transfer

I can't see a event to bind the QSPI interrupt to the DMA_CROSSBAR in the TRM.

Is there a solution to trigger the EDMA with the QSPI interrupt?

Am I missing something?

Why is the event missing?

Regards,

Simon
