[Intel Quark x1000] UART with DMA configuration (Baremetal / without OS)

[MMors]

Hello,

I am trying to configure the DMA controller dedicated to the UART in the Intel Quark x1000 SoC.

I am not able to set the "Channel Enable" CH_EN_REG.CH_EN bit to 1.

Do you have a documentation that explains the operation of the DMA controller and how to configure it ?

Thanks.

I found the answer in the Datasheet of ATMEL (Microship today).
