STM32 MCUs Embedded software

Hello.I got a STM32U599J-DK engineering sample from the ST official warehouse (don't ask me how I get this cuz I don't know either).MB1829-U599 NJQ-B01A223400084I searched the st.com and was unable to locate its resources.(user manual, datasheet, data brief, OBD binary).I wonder if any ST employee got these resources and send them to me if you please as I wish to reuse this board to it's full extent.Or, are its resources compatible with the STM32U5A9J-DK's? If so, please send me an original OBD demo of the STM32U599J-DK if available.Thanks in advance.

In your middle-ware for the usbpd i can't find any of the definition for the functions in usbpd_core.h.https://github.com/STMicroelectronics/stm32-mw-usbpd-core  Example* USBPD_PE_SVDM_RequestMode* USBPD_PE_SVDM_RequestModeEnter* USBPD_PE_SVDM_RequestModeExit Can't be found anywhere in the repo.  It looks like you compiled them all down to assembly files.  Is there a reason for this or am i missing something?

Hi Everyone,I already have IPv4 via DHCP working on STM32H753ZI with Azure RTOS (ThreadX + NetX Duo). I need help getting IPv6 via SLAAC (stateless autoconfiguration) working.   Best Regards,Divya P

Hello, STM employees,I have bought the NUCLEO-N657X0 board with the intentions of using its USB on the go module. I have previous experience with USB with STM32f401, where I had to employ a single function CDC_Transmit(), and STM32CubeIde and Hal did the rest. It was simple and easy to implement. Currently Im struggling with doing the same with the N6 MCU, but proved impossible. I've tried all tutorials found on your site and community available ones, but could not find a single example that would send "Hello World!" to my PC. I'm sure my board works as I've run a basic blink sketch from the external ROM.Please, if you could add the same middleware for f401 to n657, that would be great.

Hi all,I’m working on a custom bootloader for STM32F7, which performs OTA updates using TCP/IP (Ethernet and/or WINC3400 WiFi). The bootloader writes the new firmware to flash, then attempts to jump to the application using the standard sequence: cleaning and disabling caches, setting VTOR, setting MSP, and jumping to the application's reset handler.The Problem:If the application binary is small, everything works: the bootloader jumps and the app runs as expected.If the application binary is larger (for example, over X KB/MB), the bootloader appears to complete the OTA and jump, but the application does not start (no output, no main runs, or immediate lockup/hard fault).What I Have Tried:Verified that the full image is written to flash (checked total bytes and flash content matches binary).Cleaned and disabled D/I caches before jump.Set VTOR and MSP to the application address.Disabled all interrupts, deinitialized all peripherals, shut down the WINC3400, and reset all related GPIOs/SPI

Hello!I have NUCLEO-N657X0-Q development kit and two camera modules: B-CAMS-IMX and B-CAMS-OMV.According to the chip documentation, it is possible to connect two cameras by using CSI-2 as the primary interface and DCMI as the auxiliary interface. However, in the example projects for the N6 series, I only see implementations for working with a single camera connected via CSI-2. 1. Is it possible to implement such a dual-camera setup within a single project?2. Are there any code examples available that demonstrate how to connect both cameras (one via CSI-2 and the other via DCMI)?3. If no such example exists for dual-camera setups, are there at least examples showing how to connect a single camera via DCMI to an N6-series chip? Any guidance or resources would be greatly appreciated!

Hello ST Team,I'm implementing robust Ethernet on STM32H743ZI. Need technical guidance on:PART 1: BANDWIDTH VERIFICATIONQuestion 1.1: How to verify link speed?How to check link speed (100 Mbps)?Question 1.2: Bandwidth testing methodology?Create a TCP socket, send a large file to the PC?Expected bandwidth on STM32H743?Network overhead (TCP/IP stack)?Optimal packet size for testing?  Also, how can I debug this to check if I am using full bandwidth and if my link is down during transmission?

Hello ST Community,I'm currently developing a project on STM32H743 using TouchGFX 4.25.0 (RGB LTDC interface, framebuffer in external 16MB SDRAM) and LWIP + FreeRTOS (TCP client mode over Ethernet RMII). Everything works fine when TouchGFX is not included. However, after adding TouchGFX to the project, I'm facing strange Ethernet instability.:magnifying_glass_tilted_left: Observations:Without TouchGFX:TCP Client connects to the server reliably.No reconnection or data loss observed.Using recv() with flags = 0 works flawlessly for long durations.With TouchGFX + LTDC + DMA2D:Frequent TCP reconnections start occurring.Happens especially when using lwip_select() + recv() mechanism.If I skip lwip_select() and use direct recv() with flags = 0, reconnections stop, but after some time communication lags or stalls.:light_bulb: Hypothesis:I suspect the problem lies in AXI bus contention between:LTDC/DMA2D accessing external SDRAM (for framebuffer)Ethernet DMA accessing DTCM/SRAM or other AXI slav

Hi everybody,I'm trying to make a bootloader in my STM32F446. The aim if this one is the possibility to update the firmware but with keeping the previous one in case of issue. So, I'll have two slots for firmware.For now, I have the following sectors in my flash :BOOTLOADER : 0x0800 0000 -> 0x0800BFFF (it only uses sector 0 & 1 for code, so I use last word of sector 2 (0x0800 BFFE & 0x0800 BFFF) to write a "magic word" which gives me the information, if we're currently running on SLOT 1 or 2).SLOT 1 : 0x0800 C000 -> 0x0800 3FFFSLOT 2 : 0x0804 0000 -> 0x0807 FFFFMy FW is running on slot 1. It receives the order to update, so it restarts, checks on which slot the new FM must be copied, writes into the flash, and starts again on new slot (and this is done at each update, so FM is running on SLOT1/2 alternatively).Everything works well, except the last step, it always run on slot 1 (even if all the code has been written in the slot 2).In the two first 32 bytes (0x0800 0000

Good evening,I have been trying to get the ethernet port of my NUCLEO-H755ZI-Q to talk to my PC - and have been failing to do so now for a week.I found this manual, but it is for Cube IDE 1.9 - and even after following the described steps I fail to talk via ethernet.I did also find this github repo where I used STM32H7-LwIP-Examples/STM32H745_Nucleo_M7_ETH - and after adapting the IPs somewhat communication via UDP did work.So I am rather sure my hardware does work.But the code generated by CubeMX 2.0 does not.Can anyone provide me with eithera short manual how to configure CubeMX correctly,a ready-made example project using the current CubeMX 2.0,or any other input?The current problem with my CubeMX 2.0 generated project is that during reception I get an ETH_DMACSR_RBU /* Receive Buffer Unavailable */inside theHAL_ETH_ErrorCallback En- or disabling ICache, DCache and MPU did not have any effect. I did move the RX_POOL to 0x30040000 as per the article and adapt

We use STM32H743 to develop a system that needs to display a 1920 * 1080(8-bit pixel depths) graphic on LCD(driven by FPGA)Now our design is that STM32 reads a picture from the SD card, then decodes and sends it to the FPGA through FMC.We tried the software decoder, but it takes almost 5 seconds to decode just one PNG picture. The required time is only 50ms(about 3 FPS for each graphic, so 3*16ms = 48ms).  I just learned that STM32H743  has an internal JPEG hardware decoder, but it seems this JPEG hardware decoder does not support 1920 * 1080? So the only way is to use an external decode chip, am I right?

I've an STM32U5A9J-DK-FreeRTOS and I was looking to a way to stream audio from the PC to the board and vice-versa using the USB-C on board port.I've seen that there's a CUBE extension X-CUBE-USB-AUDIO but it feels it is specifically for the STM32F7Also, on the CubeMX, opening the .ioc file, the only USB option I'm seeing is USB_OTG_HSSo, my question is, the USB-C port on the STM32U5A9J-DK board supports it?I'm also seeing the X-CUBE-AUDIO-KIT but again it feels compatible only for STM32H series

Hello,when my rtc time goes to 23:59:59 to 00:00:00 then my program while loop is slow ex. some led toggle with 500ms toggle time is incress X2 so what is issue?

Title edited for clarity.I am trying to debug an application that is intended to run out of PSRAM on the STM32H7S78-DK. I have created a simple FSBL which initializes the PSRAM and puts it into Memory Mapped mode and then executes a software BKPT to halt the CPU. I then load an application image using the debugger (JLink) into PSRAM and start it. The application appears to run fine but I cannot get any interrupts to fire. The application running out of PSRAM establishes a new vector table in RAM and updates the VTOR register. I have tried both SysTick and an interval timer (TIM6) to generate interrupts but no success. Looking at the peripheral and NVIC registers everything appears to be correct.This is the MPU configuration for the PSRAM region: MPU_InitStruct.Number = MPU_REGION_NUMBER1; MPU_InitStruct.BaseAddress = 0x90000000; MPU_InitStruct.Size = MPU_REGION_SIZE_32MB; MPU_InitStruct.SubRegionDisable = 0x0; MPU_InitStruct.TypeExtField = MPU_TEX_LEVEL1; MPU_InitStruct.AccessPerm

I’m currently working on an STM32 project with Ethernet connectivity and LwIP. I want to know the IP address of the STM32 while configuring the network settings in CubeIDE. Here’s my setup: STM32 is connected to a router via an Ethernet cable and my laptop is also connected to same router via wifi. LwIP is being used as the TCP/IP stack. In LwIP settings, there is an option to choose DHCP or Static IP. My questions are: If I enable DHCP, how can I find out the dynamically assigned IP of the STM32? If I use a Static IP, what are the correct parameters to set (IP, Subnet Mask, Gateway) to ensure the STM32 is reachable from my PC? Are there any tips or methods to quickly verify the STM32’s IP on the network, such as through serial print, ping, or a network scanner?
