'ADC1' undeclared and 'ADC1_COMMON' undeclared

[it3]

Hello,

I am trying to create a new STM32 baremetal project for STM32MP131Axx.

Errors occurred when to build the project that ADC2 is enabled by using STM32CubeMX.

'ADC1' undeclared (first use in this function); did you mean 'ADC2'? stm32mp13xx_hal_adc.c  line 2786

'ADC1_COMMON' undeclared (first use in this function); did you mean 'ADC2_COMMON'? stm32mp13xx_ll_adc.h  line 1970

STM31MP131Axx has only ADC2 but the FW package seems to expect the definition of ADC1 exists.

I avoid these errors by modifying "stm32mp131axx_ca7.h" as below since I though it is better not to change "stm32mp13xx_hal_adc.c" and "stm32mp13xx_ll_adc.h" because they are common files for STM32MP13 series.

#define ADC1                ((ADC_TypeDef *) ADC2_BASE)
#define ADC1_COMMON        ((ADC_Common_TypeDef *) ADC2_COMMON_BASE)
#define ADC2                ((ADC_TypeDef *) ADC2_BASE)
#define ADC2_COMMON        ((ADC_Common_TypeDef *) ADC2_COMMON_BASE)

I would be appreciated if you could explain the better way to avoid these errors.

Best regards.

Hi @it3 ,

This is known issue. 

Will be fixed in next release plan for November. 

In the meantime, find the patch attached for proper correction.
