Play tones on QSPI flash directly to I2S audio DAC on nRF52840

Hi,

    According to the data sheet, nrf52840 supports XIP mode on QSPI flash. Can we configure I2S(easyDMA) to load the tone from external flash with XIP address and play it directly?

No, the EasyDMA only operates on RAM, you'll need to load the I2S samples from external flash into RAM first.
