    Spi master rx mode

    bartosz.boguszewicz

      Hi,

      I was working on SPI master peripheral on D2000 and noticed that in Receive only mode (in TXRX and TX mode everything works fine) it does not work on higher frequency than 2 MHz (Divider with value of 16, 32MHz internal quartz). When I set the clock on 2MHz and below everything starts to work.

      Right after issuing the spi irq request with said configuration Quark enters spi callback with error QM_SPI_RX_OVERFLOW. Is anything known about that issue?
