Other Parts Discussed in Thread: SYSCONFIG

Hi TI team!

I am trying to use Flash_read()/Flash_write() API via DMA, in sysconfig I enabled the option "enable DMA". How can I get a response from DMA, about reading/writing is done with qspi flash.

Regards!

    Hi Oleg.

    Please refer to the function - QSPI_edmaTransfer in source/drivers/qspi/v0/edma/qspi_edma.c to understand the flow of QSPI + eDMA read functionality.

    Writes are done in INDAC mode, so eDMAs are not utilized for the same.

    Best Regards,
