I am having issues debugging a STM32H7 series chip (STM32H755).When I connect using multiarch-gdb and run `mon swdp_scan` it crashes both cores. I am using a BMP debugger. I end up in the NMI handler. I can see via the external LEDs in the code that ...
I was using the preloaded demo for the STM32L476 Discovery board and everything was working, and then I followed the steps on the Getting started with STM32CubeL4 MCU Package user manual to try and run the first example. I followed the steps and once...
I am trying to evaluate the FDCAN function on a STM32U5 and somehow I don't manage to make it work .I can receive a frame when I am in (external) loop back mode and if the FDCAN transmits the frame but I cannot receive a frame in normal mode from an ...
Hi,I'm trying to perform analog-to-digital conversion using the DMA function on dual-core STM32H7 board series. Basically, I can not make it work. I have tried with other STM32 boards (like STM32L476RG for instance) successfully but it seems that the...
Hello,I have 2 EVAL board, one STM32H743i-EVAL2 and one STM32H7B3i-EVAL.Both have the same NOR Flash chipset MT28EW128.I'm using the function HAL_NOR_ReadBuffer to read data from the NOR.but, "sometimes", the data I read are corrupt.I made my project...
Hello everyone once again, i am trying to split the main flash memory (just by using the .ld file) to put in each one a specific code (bootloader, DFU, app), i did what you can see in the image below, but i am not sure why the DFU and FLASH sections ...

I was Displaying HSI on Serial Port using Alternate Functions, as soon i enabled the HSI i got the following error messege.Target no device foundReason: No device found on target.Looking Forward for help.Regards.
I use STM32H753 and USART1 with DMA to receive data of unknown length (Min: 8 bytes Max: 512 bytes) from PC. Data will be sent in burst after every one second. My baud rate is 9600. So approx 1ms per byte.So, maximum, I'm going to get all the data in...
