Overview

Package nocache allows to allocate variables and slices of arbitrary type in the DMA-capable non-cached memory. The allocation is permanent (there is no way to free allocated memory).

The size of the non-cached memory is MCU specific (256 KB in STM32H743).

If the MCU doesn't use data cache and there is no other memory available in the system then normal heap allocation is used.
