Sorry, I misunderstood your initial post. I have updated my answer to avoid confusion.

Ok, but problem is not in SDK. Problem is in hardware limitation.

Hi,

This feature seems to not be available in the engineering A revison of the nRF52840. I have added a request to change the documentation or add this to the errata document.

The drivers in the SDK is written to support EasyDMA on nRF52832, which is limited to 255 bytes transfers. When this feature is available in the chip, the SDK drivers will be updated to support this.

Best regards,

Jørgen
