STM32 MCUs Embedded software

I've created a project for stm32H745 (dual core) and add the threadX support from software package, but I see it only for the CM4, not the CM7 (and I have also free-rtos selected which is enforced for both). Is it correct?

Problems with UART Interrupt Receive

Hello, i have a STM32F407VET6 MCU and i have problems with UART3 and Interrupt Receive, it does not work.UART3 is connected with a Display, my MCU sends every Second a "PING" and the Display answers with "PONG", that works fine.Global Interrupt for U...

Hi everyone I am using stm32l496 and I am trying to disable all the interrupts while running sensative routines. to disable all the interrupt I am using __disable_irq and to enable them  __enable_irq.But nothing seems to happen, even after I use disa...

not able to ping the STM32H750 device intermittently

Hi,Our project is using STM32H750 together with µC/OS-III as the OS and µC/TCP-IP as the network stack.The device is able to be assigned with an IP address by DHCP server.And the device can respond to ping initially.But if we ping the device continuo...

D-cache invalidation call causes Hard Fault (D-cache is disabled)

Hi. I'm using an STM32H7, and I have the d-cache DISABLED in cubemx, but __DCACHE_PRESENT seems to always be set to 1 by stm32h755xx.h, anyway, and as a result, I'm getting a hardfault when X-CUBE-AZRTOS-H7 ethernet init calls SCB_CleanDCache_by_Addr...

Virtual Com port not working with CubeIDE and ST-Link?

I am attempting to debug an Azure RTOS example (NX_TCP_Server_Echo) but I am not receiving any messages on the VCOM port. In device manager I can see that the STLink Virtual Com Port is assigned to COM8 at 115200 bps. So I attach my Hercules Setup ut...

Nx_Azure_IoT example adapted for our STM32U585QII6Q board . Every time STM32CubeMX regenerates the code, it deletes three files: nx_tcp_socket_driver_establish.c, nx_tcp_socket_driver_packet_receive.c and ...

I have adapted the Nx_Azure_IoT example for my board with an STM32U585QII6Q. My problem is that every time STM32CubeMX regenerates the code, it deletes three files that I added: nx_tcp_socket_driver_establish.c, nx_tcp_socket_driver_packet_receive.c ...
