ChibiOS Free Embedded RTOS

Hi,

The problem came from: stm32_registry.h , line:2386

/*===========================================================================*/
/* STM32F334x8. */
/*===========================================================================*/
#if defined(STM32F334x8)
/* ADC attributes.*/
#define ...

Hi,

The device is STM32F334R8.

I also found that ADC1 did not measure correctly and for ADC2 there's no data written to [&adcsample_t].

Adress: 0x800357C is outside of _stm32_dma_streams scope.

I think may be is bad pointer arithmetic, but don't have time to investigate at the moment.

Workaround:

In file: adc_lld.c change line:

ADCD2.dmastp = STM32_DMA_STREAM(STM32_ADC_ADC2_DMA_STREAM);

with:

ADCD2.dmastp = STM32_DMA_STREAM ...

Hi,

When I try to use ADC1 and ADC2 with DMA, after initialization data in DMA section of ADCDriver struct is wrong.
Actually, the data written over DMA pointer is: "DMA failure":
