STM32U575 ADC DMA Interrupt not working

[Bhavik]

I have Nucleo U575ZI-Q board and I am trying to unable ADC with DMA and Interrupt but not able to get any reading.

I am trying to see the adcBuf value in live expression but it is not working.

#define max_channel 2
uint32_t adcBuf[max_channel];
uint32_t test=0;

Hello @Bhavik​,

Which STM32CubeMX version are you using?

Try to move the MX_GPDMA1_Init(); line code before MX_ADC1_Init(); in your main.c.

Hi @Bhavik​ ,

If you use the STM32CubeMX 6.7.0 ​ version could you please share the .ioc file?

Thank you.

@KDJEM.1​ I tried in two different version of the STM32CubeIDE which are 1.10.1 and 1.9.0

@KDJEM.1​ No I am not using the CubeMX

Hello @Bhavik​,

Try to use the last version for STM32CubeIDE1.11.0.

You can download the latest version from this link.

Please let me know if the problem is solved.

Thank you.

@KDJEM.1​ No update issue remains same. I am trying to debug and can not see any change in the variable test as well as adcBuf.

@KDJEM.1​ Even I tried to close the DMA and just make it work on simple interrupt base but no success. It is returning the error on first time and busy on second time call for HAL_ADC_Start_IT(&hadc1)
