NO ADC DMA interrupt on F446RET6, CubeMX 6.7.0, FW4_1.27.1

Hello!

I have faced the problem with ADC checking using DMA on my F446RET6 MCU. The software tools are CubeMX 6.7.0 and CubeIDE 1.10.1. The Firmware is FW4_1.27.1. Perhaps, it is my mistake, but i canntot understand how to fix it. Here is the simple project directory in cubeIDE https://www.dropbox.com/s/g1o8yunmubjjmk1/F446_ADC_DMA.zip?dl=0 together with .ioc file.

After HAL_ADC_Start_DMA(&hadc3, (uint32_t*)c_buff, ADC_CCONV); call there is no HAL_ADC_ConvCpltCallback() interrupt, yet i could not capture the interrupt inside the standard DMA2_Stream0_IRQHandler().

Looking forward for your advice.

Hello @sfrwmaker,

Could you disable your WWDG Mode, it works just fine for me.
