I'm trying to build an audio project using STM32H747 MCU. I wish to configure the cortex M7 to process the audio in and out buffers. I'm trying to work with double buffers of input and output. the DMA should handle the transactions to and from the i2...

I'm working on the STM32H747-DISCO Board, and studently the onboard ST-Link-V3 stopped recognizing the STM32H747 MCU.No matter what i do, it wont find the target,when I connect a simple STM32F411-DISCO everything works as expected.Rebooting the Power...

I request ST's employe's help, and exact explenation and instructions on what to do to make the STM32H747 work with fullduplex I2S and DMA stream, i.e: HAL_I2Sex_TransmitRecieveDMA. It's ST's FLAGSHIP MCU and it's simpely not working out of the box.

OK so just to be clear,the catch is disabledmy code is attachedhere is what I've added to the Flash.ld file: .ram2Block (NOLOAD) :{KEEP (*(.MY_RAM_D2))} > RAM_D2then I defined the buffers:__attribute__ (( section(".MY_RAM_D2") )) uint16_t inBuffer[2]...

Thank you, the MCU is now operational !!

Do I need to change a boot resistor of the MCU ? Or change the value given to Boot0 or Boot1 pins ? What should I do exactly ? Ive tried connecting to the MCU wice CubeProgrammer before and erase, but couldn't.. What am I missing ?
