I don't know where the "HAL_MDMA_Start (" function is located.In "stm32h7xx_hal_mdma.c" we find references to "HAL_MDMA_Start (", but not the code. On the other hand there is the code of "HAL_MDMA_Start_IT (".I am using STM32CubeMX / IDE to generate ...

Hello, I am working on a card with an STM32H745 processor.I have a few questions regarding debugging (with a V3 probe):1) is it possible to make a hard reset of the chip?2) is it possible to reset the cores independently?3) is it possible to do some ...

Hello,When you associate a "user label" with a GPIO (for example DEBUG1 associated with PB11), the associated constants are sometimes not defined in the main.h file (but sometimes yes). When it is not, the associated initialization of the port is als...

Hello Imen, Thank you for your prompt response...Here is the ioc file.In my code:#define HSPI_ADS hspi1and the associated DMA is now GPDMA1_Channel1 Jean-Louis

Thank you,I don't know why, but I didn't have the function in the file (maybe an unhappy Ctrl-X)... After reinstalling the package, I have the function in the right place!

Thanks for the link ... I hadn't seen the button!This is the first time that I seriously use Eclipse (I know, Keil IAR, Segger ...), it is a bit trying experience to do hard debugging.The solution you recommend for connecting does not work for me qui...

Hello,Thanks for your code.Are you sure of the value 19 (which corresponds to a region of 1MB)? Isn't it 0x19 rather which corresponds to a region of 64MB?cf stm32h7xx_hal.c :#define MPU_REGION_SIZE_64MB ((uint8_t)0x19)Jean-Louis

Hello,I do not know if your problem comes from there, but I also had DMA problems which came from the fact that initialization MX_DMA_Init () was done after the initialization of the device (Cube 5.5.0)After moving the initialization just after that ...
