SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

How To Use DAC on STM32F4 Discovery?

The HAL_DAC_Init() function is not expected enable the associated module clock. That job is expected to be done by the HAL_DAC_MspInit function(). Since you didn’t define one, the compiler brought in the “weak” definition from stm32F4xx_hal_dac.c which is an empty function. When CubeMX generates code for the DAC, it will create a HAL_DAC_MspInit() function that enables the clock and configures the selected GPIO as DAC output.

All HAL drivers use this model of having the low-level clock and I/O setup done in a MspInit() function.
