on my board there is a 512kBit FRAM connected to the SPI interface. The interface is configured to spi-max-frequency = 40MHz ( which results in a clock frequency of about 36 MHz). But writing 512kBit lasts ~0.6 or ~1.2s depending on eoq- or tcfq-irq-mode, which is too long for my application. It seems IRQ based transfer is not fast enough. Is there the possibility to configure DMA for SPI transfer?
