I'm struggeling with the I2S where the Datasource is an QSPI Flash (2 Datalines) on a STM32F446. How can I set on the right way the pointer to the Flash in the Function HAL_I2S_Transmit_DMA() for the DMA Transfer between Flash and I2S.
my Pointer to the Flash Memory (mappedmemory) is
__IO uint8_t *qspi_addr = (__IO uint16_t *)(0x90000000);
For supporting thanks a lot in advance.
