Hi everyone,I am trying to generate an arbitrary PWM waveform using DMA burst write according to AN4776. It works in principle, except of one thing: If i want to have more than one pulse with a specifig period/pulse setting, the RCR should be used. H...

Hi everyone,I observed a strange behaviour while creating software for a STM32F091. I am using CubeIDE and HAL. FreeRTOS is used as well. The application is running as expected so far, but when I try to run it in debug mode it does not work. It crash...

Hi everyone,I have configured my ADC on STM32F405 in Scan mode to read 5 channels. What I like to do ist to make a single DMA transfer to sample the 5 channels more than one time (e.g. 10x5channels = 50 elemet DMA transfer) To average the data after ...

Hello everybody,after a long fight I got the SDMMC2 interface running in 1 bit mode on the STM32H755. I thought running it in 4 bit mode in the next step should be no big deal anymore; what a naive assumption...The SDMMC is running with FATFS and FRE...

Hi Folks,I experienced a weird problem when I tried to use the SDMMC interface on the STM32H755 Nucleo board.I set up a very basic test program. I use the template for the H755 Nucleo in CubeIDE. I set the H7 clock frequency to 480 MHz and the M4 clo...

I have founde the mistake. The problem was that the burst transfer and DMA transfer was related to Capture Compare and not to update event. I had to configure the DMA channel to "TIM1_UP" and to call the burst transfer byHAL_TIM_DMABurst_MultiWriteSt...

Ok,it seems it was an Boot issue. The Boot0 pin was not connected properly. I made a ghetto-fix on the pcb, however that was not sufficient. Need to check if the fix has been done correctly. So I changed the Option Byte to force booting from flash an...

@jan and @Clive: That are good hints. I suspect a slack joint at the BOOT0 pin. I have to check this when I am done with the grind today...Best regards

Yes, I have done so. Debuggin runs for a few lines it crashes.

I set up a new test project without RTOS an so on just with a blinking LED. Same behavior...
