Hi all, I am experiencing a problem with the DMA of the STM32WBA52 (on the NUCLEO-WBA52CG board) when using it to transfer data from FLASH to USART1 TX : part of the transmitted data is modified, i.e. not the data that is found in FLASH)The problem o...

Hi all, I am looking for a list of resources (peripherals, memory, etc) that are required by the STM32_WPAN stack implementation for the STM32WBA52. I previously used the STM32WB55 and e.g. AN5289 lists which peripherals are shared with the M0/BLE co...

Processor: STM32L562QEIBoard: proprietaryWhen connecting STM32CubeProgrammer to my STM32L562QEIx board via USB, I get a Hard Fault interrupt.The USB interface is initialized with MX_USB_Device_Init() and STM32CubeProgrammer correctly detects it. But ...

Hi All, I have a start up problem with the STM32L562QEI6.While using the STM32CubeIDE debugger, the code runs fine but without the ST-LINK/V2 connected, the board remains "dead" after applying the power supply.When I manually pull the nRST pin down b...

Hello Joe,In the example code, there is nothing else that is running (no radio is configured). So no clock switching issues. Those would also be less reproducible I think.It would also not explain why it only occurs when transferring data from Flash ...

Merci !This is indeed the kind of document I was looking for, and it was already in my project :-).I found out myself most of it by looking at the platform-specific code but it is nice to have it documented.What is just missing, in my opinion, is the...

OK, with help from ST, the cause was finally discovered : The code generated by STM32CubeMX in usbd_dfu_flash.c is incorrect.FLASH_If_Read() returns USBD_OK (0x00) while it should return a pointer.Replacing the return with something like 0x08000000U ...

Hi Tesla, Pinning down the cause of the hardfault is indeed not the hardest part and I do have a handler that shows me where the error occurred.If you read my post again, you'll see that I mention which pointer is NULL(in both the DFU and CDC modes) ...

I forgot to mention that the CTR interrupt mask bit is 1, meaning that the interrupt is enabled. It is really the CTR bit itself that never gets set when USB is connected at startup
