How to configure ADC_DMA in ethernet using NUCLEO-H745

[ggowd.1]

Hello Team,

I have implemented ADC_DMA (circular mode) Multiple channels in NUCLEO_H745 and in that added ethernet without RTOS when ethernet is implement ADC_DMA is not working it provide only one time data but i have configured for circular mode every 1HZ I need to get new data but after ethernet is implemented I am getting only I time data, So is there any memory mapping I need change any configuration in code?

> SCB_InvalidateDCache_by_Addr((uint32_t *) &aADCxConvertedData_1[ADC_CONVERTED_DATA_BUFFER_SIZE], ADC_CONVERTED_DATA_BUFFER_SIZE);

This is problematic. Points to the end of the array, not the beginning, and has the incorrect size. May or may not be the problem.

SCB_InvalidateDCache_by_Addr(aADCxConvertedData_1, sizeof(aADCxConvertedData_1));

 > hadc2.Init.ContinuousConvMode = DISABLE;

Possibly this should be enabled.

Disabling cache during the debugging process is an option.
