FreeRTOS: Stack overflow checking mechanism missing.

Hello,According to https://www.freertos.org/Stacks-and-stack-overflow-checking.html, i.e. the FreeRTOS reference, one needs to set configCHECK_FOR_STACK_OVERFLOW to 1 or 2 in order to activate stack overflow checking. In case of a stack overflow Free...

Is there an example using USBX with the two USB ports available on the STM32H7?

Currently looking to design a board with STM32H7 with two independent cellular modems, each on their own USB port to the STM32H7 processor. I have USBX working with one of the controllers, would like to know if there is any example of using USBX wit...

This is a log file of the B-U585I-IOT02A running the project Nx_Azure_IoT, STM32CubeExpansion_Cloud_AZURE_V2.1.0, with the ST MB1329 extension board connected in STMod+2, CN2. Looking the log is it possible to deduce what problem we have?

STM32L4R9 SPI bootloader. Strange behaviour after executing global mass erase command

I'm programming an STM32L4R9 through SPI according to the AN4286 application note.The problem I have is that after a global mass erase command (0x44) it won't let me execute the read memory (0x11) or the write memory (0x31), even if I wait several se...

32F417: mod for low_level_input to discard broadcast packets before LWIP

This should be possible, in the code which moves data from the ETH controller's buffers to LWIP's buffers.I am aware of the BFD bit of ETH_MACFFR solution, which works, but it makes the box useless unless it is addressed by MAC# directly. The broadca...

STM32F401CC CubeIDE + X-CUBE-AZRTOS generate call to non-existing Function HAL_PWREx_EnableOverDrive() in main.c when generating code

Hi all!I'm working with an STMF401CC chip, and all tools up to date as of today.Code generation calls above mentioned function in SystemClock_Config() in main.c.In stm32f4xxhal_pwr_ex.c this function clearly is not available for STM32F401 devices, bu...
