STM32 Tutorial #30 - Sine wave (Dual DAC) with DMA under FreeRTOS
In this exciting video we will generate TWO beautiful sine waves on both of the STM32F405 DACs (Digital to Analogue Converters). We will be using DMA and let FreeRTOS handle the scheduling of the callbacks. Sampling rates in […]

The idea is that you can run stock-ish Android on the ARM chip, which might be easier. Then you have some custom code on the RISC-V side (Linux, FreeRTOS or bare metal). I like RISC-V, but it’s a lot of complexity in tooling. Maybe if you’ve invested a lot in some RISC-V assembly code for AI.

Don't know at what level thats implemented. Assuming that those didn't have direct access to FreeRTOS to do whatever it shouldn't affect anything if there is any sort of abstraction in-between. FreeRTOS is barely an OS and mostly threading primitives. Those map very 1:1 over to the Zephyr Kernel.
