However there is no connection from D3 domain to D1 or D2 domain. This DMA is used in most cases. This controller is mainly used for handling D1 peripherals and memory to memory transfers. Below are the possible MPU configurations. Other configurations are not suitable for DMA buffers and will require cache maintenance oprations:.

In some linkerscripts, the initial stack is defined separately. So you either need to update it with the section, or define it inside the section like:. Place section to D2 RAM you can also specify your own memory regions in linkerscript file :. This is without default value initialization. Otherwise you need to place special symbols and add your own initialization code.

I have done this using another DMA Memory-to-memory and it works great. I have spent whole day of trying to get MDMA working in that way, but I always get unsatisfactory results, i. Triger mode : Buffer transfer, block transfer, Repeat block transfer and Full transfer. List type : Linear, Circular and Buffer Length. But I never seems to be able to copy the whole aray B. Could somebody help me on how to configure the MDMA settings for this case? All rights reserved STMicroelectronics.
