Hi all,
I generated code in STM32CubeMX for STM32L081CBTx controller with AES enabled.
I built the generated code (without modification) in STM32CubeIDE, but it failed with warning:
../Core/Src/stm32l0xx_hal_msp.c: In function 'HAL_CRYP_MspInit':
../Core/Src/stm32l0xx_hal_msp.c:94:5: warning: implicit declaration of function '__HAL_RCC_AES_CLK_ENABLE'; did you mean '__HAL_RCC_ADC1_CLK_ENABLE'? [-Wimplicit-function-declaration]
and error:
../Core/Src/stm32l0xx_hal_msp.c:94: undefined reference to `__HAL_RCC_AES_CLK_ENABLE'
because in stm32l0xx_hal_rcc_ex.h __HAL_RCC_AES_CLK_ENABLE is not defined for STM32L081xx controllers.
Here is the relevant code:
#if defined(STM32L062xx) || defined(STM32L063xx)|| defined(STM32L082xx) || defined(STM32L083xx) || defined(STM32L041xx) || defined(STM32L021xx)
#define __HAL_RCC_AES_CLK_ENABLE() do { \
__IO uint32_t tmpreg; \
SET_BIT(RCC->AHBENR, RCC_AHBENR_CRYPEN);\
/* Delay after an RCC peripheral clock enabling */ \
tmpreg = READ_BIT(RCC->AHBENR, RCC_AHBENR_CRYPEN);\
UNUSED(tmpreg); \
} while(0)
I have not dug deep into the datasheets and register descriptions yet, so I'm not sure what the proper solution is, but in the stm32l081xx.h RCC->AHBENR and RCC_AHBENR_CRYPEN are both defined, so just adding this family to the #if line is enough for successful build.
(I don't have hardware to test it.)
#if defined(STM32L062xx) || defined(STM32L063xx)|| defined(STM32L081xx) || defined(STM32L082xx) || defined(STM32L083xx) || defined(STM32L041xx) || defined(STM32L021xx)
