SPI with DMA cannot be used Rx/Tx FIFO

ID: COBALTSDK-970

Status: Open

First reported: 10.2.4.44

Fixed in: TBD

Description

When using the hardware SPI interface in combination with the DMA, it is not possible to use a FIFO level different from 0. Otherwise there is a risk to loose data during SPI transactions.

Workaround

When configuring the SPI adapter driver in combination with the DMA, make sure the fields rx_tl and tx_tl are set to 0.
