hello zephyr users
i'm using the stmf469i discovery board and i'm trying to enable some stm32 hal drivers but, try as i might, i cannot.
so for example, if i look in menuconfig for CONFIG_USE_STM32_HAL_DMA2D it appears but it is in red. if i press ? for information:
Name: USE_STM32_HAL_DMA2D
Type: bool
Value: n
Help:
Enable STM32Cube Chrom-Art Accelerator™ controller (DMA2D) HAL module

help
Enable STM32Cube Chrom-Art Accelerator™ controller (DMA2D) HAL module
driver
working back it says it
HAS_STM32CUBE (=y)
SOC_SERIES_STM32F4X(=y)
yet i can't explicitly enable that specific CONFIG_USE_STM32_HAL_DMA2D and i can't include it in the prj.conf (errors about not being able to explicitly set it) and so i don't know what to do.
in my code i could
#include <stm32f4xx_hal_dma2d.h>
and compile without errors however the linking process failed whenever i tried to access a function, eg: HAL_DMA2D_Init. so it's like the environment knows i want to use that HAL and makes the include available to me, but i can't complete the build.
so i don't know if i'm getting hung up on the idea of whether linking will work if i could only enable CONFIG_USE_STM32_HAL_DMA2D or whether there is another way to get my project to compile/link the required hal driver, or indeed whether there are other options i'm not aware of.
when i look in
zephyrproject/modules/hal/stm32/stm32cube/stm32f4xx/CMakeLists.txt
there is a whole lot of stuff about zephyr_library_sources_ifdef(CONFIG_USE_STM32_HAL_[all the things i would like to enable but cannot]) but the problem is i can't actually enable any of them.
anyway i tried google every which way and i'm stuck, so if anyone can help a brother out i'd be over the moon, cheers all, tristen.
