Nucleo H755ZI-Q how to get a ping with RTOS+LwIP

Hello there,I have issues to get Ethernet working with the STM32H755ZI-Q board. I have checked out the knowlege base article with no luck yet (https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working)....

STM32 setup with 2 x HS controllers

Hi, I'm trying to implement stm32f7 discovery cube package example. (USB Mass Storage) in High speed mode. I inserted microSD card into slot. after i build and load the image into the memory , i can see the files inside microsd card.

but when i start to copy and paste these files to another location . i can not get the true speed. (while writing reading) I mean I choose HS mode (60Mb/s) but transfer speed is too low. I made everything in the readme.txt file. but i can not impleme...

How to execute a program uploaded with JTAG on a target configured to start bootloader

 Hi, We received a custom board built around a STM32L476 MCU. I could program it with a basic "Hello World" program which aims at blinking some leds. But the leds do not blink... :( using debugger, I noticed 2 strange behaviors 1) call to HAL_Delay()...

I will use with my STM32H745 Disco Board the eMMC memory together with the Flash File System.

I wanted to use with my STM32H745 Disco Board the eMMC memory together with the Flash File System. In compare to (https://community.st.com/s/article/how-to-create-a-file-system-on-a-sd-card-using-stm32bubeide), the selection for the hardware is graye...

HAL_OSPI_Command_IT vs HAL_OSPI_Command, when cmd->DataMode != HAL_OSPI_DATA_NONE

Hi, dear colleagues!I use OSPI interface to connect MCU with QSPI NAND flash.For some commands (for ex. PAGE READ) of used NAND device there is 0 data bytes and HAL_OSPI_Command_IT() work proper.But some commands (for ex. SET FEATURE) has one (or mor...

I am just about to start a journey as embedded software developer, and I am trying to familiarize myself with a STM32L1 discovery kit - the initial feeling is one of bewilderment.

After I successfully attached the board to my laptop and ran the "Press a button to ...." tests my plan was to proceed to the source code of the demo application:To read through the source code to familiarize with it.To compile it on my laptopTo flas...

HAL_UART_Receive_DMA(&huart1,... and HAL_UART_Receive_DMA(&huart2,.... Usually work well but not if I use in the same program TIM2 with the following instruction HAL_TIM_Base_Start_IT(&htim2).... The timer TIM2 keep working.
