This happens 100% reproducibly at frame 16383, never at any other frame3. Without SDRAM (FMC) and LTDC active, the issue does not occur for 1.5+ hours4. With SDRAM only: occurs after ~7 minutes5. With SDRAM + LTDC (framebuffer in SDRAM): occurs within seconds6. Temporarily shorting USB3300 VCC to GND with a probe (adding bypasscapacitance) eliminated the issue for 50+ minutes — suggesting powersupply noise is a contributing factor, but the frame=16383 correlationis too precise to be purely noise-drivenQuestio

Hi, is anybody able to confirm if the STM32H563ZIT3Q has an ethernet peripheral? Thanks, regards. 

So I have a series of PIN configured as Application and/or Boot only but, for some reason, the CubeMX generates the code on both main.h in Appli and Booti.e.I have PC0 set as Application only context but I found it in the Boot as well 

I've been struggling with a strange ADC problem for a while, and have now made some interesting observations.The scenarioI'm using an STM32G474, where HRTIM directly controls a peltier driver for temperature regulation. Temperatures are measured by ADC4 (12 bit resolution), running in DMA circular mode, triggered by TIM7, at 1 kHz. This works. Temperatures are coming in, and are being used for PID regulation.The problemQuite often – perhaps always – some of the temperature readings are being disturbed, but only at certain temperatures. At first, I thought that it was random noise, but in a graph the noise looks strange. Not random at all.After monitoring the raw ADC values that the DMA has thrown into memory, I discovered something that might be a clue – or it might just be a source of confusion. Every time a noisy sequence occurs, the ADC readout jumps to a lower nearby value where the five least significant bits are all 1, i.e. xxxx xxx1 1111. This is not random noise. It is if as th

Hello.I installed a new version of the IDE, exactly this:st-stm32cubeide_2.1.1_28236_20260312_0043_x86_64The problem is that the menu option "Manage embedded packages" is missing:I checked this on two computers with Windows 10.During the installation, there were no error messages.What can be done about this? 

Hello, I am using a B-G431-ESC1 board to power some BLDC motors. I have alrady used it succesfully to spin some 2 pole pairs BLDC using Hall sensors for speed control. I even managed to implement some code to stop the motor at every half rotation of the shaft. It worked flawlessly with this type of motor. Now, I tried connecting a different type of BLDC, still 2 pole pairs but thats all I know since I don't have the datasheet. The motor profiling part went as expected and it managed to calculate all the relevant properties of the motor. I saved it and implemented the Hall sensors as aux speed control for Hall profiling. The difference from the other type of motor is that this one has a 6-wire Hall connection. Using an oscilloscope, I found that the extra cable was likely for temperature, so I left it unconnected. However, I keep getting Pin not connected on the pin wher the same cable is plugged (the blue cable). Whether I put the blue cable on H1, H2 or H3, the board doesnt recognize

Hi, On STM32F746G-DISCO board I have a problem with USART1 (ST-Link VCP): - TX (PA9) works fine – I can send messages- RX (PB7) doesn't receive any characters and I think the board is not waiting for commands Tested both polling (HAL_UART_Receive) and interrupt mode (HAL_UART_Receive_IT). Pins are configured correctly. Did anyone have similar issue on this board? Any ideas what can block RX?

I have been working on porting a custom board using the STM32MP255F-AK.I performed the following tasks:- Used STMCubeMX to configure pins and other settings- Manually added the custom board-specific sections to the DeviceTree- Added the DeviceTree to the Distribution Package's meta-st/meta-stm32mp-addons/mx directory- Created a custom board configuration file and performed the build- Wrote the resulting TF-A and FIP images to an SD card and booted the system- Before performing this work, I verified the operation of STOpenLinux, which was created by modifying the STM32MP257F-DK Device TreeThe TF-A boots, but just before U-Boot starts, a register dump occurs repeatedly and the system stops progressingJudging by the error details, it appears to be a security-related error.Based on the address where the error occurred and the error ID,I tried making various changes to the .ioc and DT files, but the issue persisted.I suspect it’s a simple configuration mistake...What specific areas should I

Hi all,What is the recommended way to not crush our repository and dynamically pull/generate the project's Drivers and Middleware folders?  For instance, our repository has both Bootloader + Application code projects in a repo (and other MCU projects/layouts for the same board).Is there something similar to Platform.IO (or C#'s NuGet packages) where the platform maintains those 3rd-party files in a volatile location and pulls them if they don't exist on your machine? Especially for the sake of not checking into the repo duplication of +15 MB worth of files for each project.Please excuse me if this was already asked. I didn't quite find a solid answer.I'm ok with making a command line script that auto-pulls them too, if that's a possibility.

Hi all,I am trying to develop a bootloader software for STM32F765.I requires two features in it.1) jumping from Bootloader to Application2) jumping from Application to BootloaderI could make jump from Bootloader to Application very easily.But I am suffering with jumping from Application to Bootloader for 4-5 days now.The final code I tried is given below:void Bootloader_JumpToBootloader_Program(void) { void (*app_reset_handler)(void); __disable_irq(); SysTick->CTRL = 0 ; SysTick->LOAD = 0; SysTick->VAL = 0; HAL_RCC_DeInit(); HAL_DeInit(); /* 2) disable all enabled interrupts */ NVIC->ICER[ 0 ] = 0xFFFFFFFF ; NVIC->ICER[ 1 ] = 0xFFFFFFFF ; NVIC->ICER[ 2 ] = 0xFFFFFFFF ; NVIC->ICER[ 3 ] = 0xFFFFFFFF ; NVIC->ICER[ 4 ] = 0xFFFFFFFF ; NVIC->ICER[ 5 ] = 0xFFFFFFFF ; NVIC->ICER[ 6 ] = 0xFFFFFFFF ; NVIC->ICER[ 7 ] = 0xFFFFFFFF ; NVIC->ICPR[ 0 ] = 0xFFFFFFFF ; NVIC->ICPR[ 1 ] = 0xFFFFFFFF ; NVIC->ICPR[ 2 ] = 0xFFFFFFFF ; NVIC->ICPR[ 3 ]

Hello,   I'm updating an ST25R3916B project to use the ST25R300 due to the obsolescence of the Murata variable capacitor. This project is read/write of ISO15693 tags only, no card emulation or anything fancy. It uses one IC which is then multiplexed with relays to 20 different antennae, each about 2cm square. The tag that we're reading is about 2cm by 1cm, and has been working reliably. So for this update I start by finding all the reference designs, and I saw this little gem, the STEVAL-ALOCKCB. It looks like it has an antenna the same size - how do I get more information about it? Can you please post the dimensions, or even better just send me the Altium files and I can get it out of there cleanly. Reference designator on there is ANT700.Also one question on that design - on PDF page 8 of the schematic it has the filter and antenna match but it looks like it's duplicated on both sides of the connector - why? Is that in case someone wants to use a different antenna at t

IN short, it's not working. I normally use the standard (not x-cube) and L5 processors.  I'm going to the U5 processors for a larger project.  I've gone to Cube MX 6.17.0 and CubeMXIDE 2.1.1. Starting with a blank project, I configure the pins as usual and enable xcube-FreeRTOS.  Go to CubeIDE, and without FreeRTOS, everything compiles properly.  With FreeRTOS, I get 237 errors, some understandable, and some of the following: ./Middlewares/Third_Party/FreeRTOS/Source/include/task.h:34:6: error: #error "include FreeRTOS.h must appear in source files before include task.h" 34 | #error "include FreeRTOS.h must appear in source files before include task.h" | ^~~~~ In file included from ../Middlewares/Third_Party/FreeRTOS/Source/include/task.h:37: ../Middlewares/Third_Party/FreeRTOS/Source/include/list.h:62:6: error: #error "FreeRTOS.h must be included before list.h" 62 | #error "FreeRTOS.h must be included before list.h" | ^~~~~ ../Middlewares/Third_Party/FreeRTOS/S

I'm trying to install the ST-Link USB Drivers following the instructions here. However, the STM32Cube Resources section does not include ST-Link USB Drivers.I'm running the latest versions on VS Code and STM32CodeIDE extension. 

I'm writing firmware for a development board based on the STM32H743 MCU, and I want to use an external GPIO input as the trigger or synchronization signal of DMAMUX to initiate DMA transactions. However, it seems that very little information is available on using GPIOs to start DMAs. In the reference manual, "Table 127. DMAMUX2: assignment of trigger inputs to resources" and "Table 128. DMAMUX2: assignment of synchronization inputs to resources", it shows two trigger input signals: "Syscfg_exti0_mux" (number 20), and "Syscfg_exti2_mux" (number 21). So it seems to suggest that the EXTI trigger sources can indeed be used to trigger the DMA, but these two signals are not mentioned anywhere in the entire reference manual, there's no block diagram showing exactly what GPIO pins are connected. It says "SYSCFG" and "MUX", so they're probably the outputs controlled by programming SYSCFG_EXTICR1, SYSCFG_EXTICR2, SYSCFG_EXTICR3, SYSCFG_EXTICR4. But there are 4 EXTICRx and only two "exti_sys

Hi, I need to measure a 4.2V battery while my MCU's supply varies between 2.0V and 3.3V. Since VDDA is the ADC reference, raw ADC counts will drift as the supply changes. Is this the correct method? My plan: Feed the battery voltage through a 10K/7K5 divider into one ADC channel (scaled to stay below VDDA_min = 2.0V). Read VREFINT on a second ADC channel. Use VREFINT (whose true value is known from the factory calibration in system memory) to back-calculate the actual VDDA, then convert the battery channel's raw count into volts. The formula being:V_battery = 3.0 V × (VREFINT_CAL / VREFINT_DATA) × (ADC_battery / 4095) × ((R1 + R2) / R2)   Is this the correct approach for getting a supply-independent battery reading on this part? Anything I'm missing... sampling time for VREFINT, divider impedance vs. ADC sample-and-hold, or calibration register quirks specific to the C0 series?   Thank you

X-CUBE-FREERTOS for STM32U0. I don't see the configUSE_TIME_SLICING parameter in the GUI. It's also missing from the generated FreeRTOSConfig.h file.What multitasking mode will be used?

Hi! I'm trying to design a project that will use an stm32u5, and I would like to add PSRAM to it. Most higher-capacity PSRAMs seem to want to run at 1.8V rather than 3.3V, from what I can tell.  The particular U5 I've tentatively selected (the U595), has a VDDIO2 power pin, which I understand that I can run at 1.8V while running the rest of the MCU at 3.3V. This feature seems specifically designed to address this use case (and Claude and Gemini insist that it's possible with the right u5 variant, though I'm well aware how confidently wrong AI tools can be). The datasheet says that VDDIO2 affects Pin Bank G. However, I can't quite seem to figure out how I might actually connect to a PSRAM chip exclusively with this bank.  I haven't been in these waters before, so it's possible I'm overlooking something straightforward - a lot of the configuration options for PSRAM are new to me. It seems I could use FMC or SPI to connect to the PSRAM chip, but playing around in cubeMX with all

In the code examples provided with AN4502, this pattern is used often:  while ( STACK_SMBUS_IsReady(pcontext) != SMBUS_SMS_READY) { } But in our code, when built with the Release CMake preset, this hangs forever.My understanding is that this is because the `StateMachine` member of the SMBus context struct (SMBUS_StackHandleTypeDef) is getting updated by the SMBUS interrupt handlers, but it isn't marked volatile:  * @brief Stack state machine handling structure - the stack operation context */ typedef struct { uint32_t StateMachine; /*!< Keeps track of current stack state */ SMBUS_HandleTypeDef *Device; /*!< HAL driver handle */ uint8_t *ARP_UDID; /*!< A UDID used in ARP */ st_command_t *CurrentCommand; /*!< NULL, unless a command is being processed */ st_command_t *CMD_table; /*!< Pointer to first record in the table of all supported commands */ uint32_t CMD_tableSize; /*!< The supported commands table size */ #ifdef PMBUS13 SMBUS_ZoneStateTyp

Hi, I would like to use MDMA to get values from ADC. I have one adc set with 6 channels, starting conversion with timer (100µs). So I would like to save in memory adc values like that : val1, val2, val3, val4, val5, val6 -> val1(100µs),val1(200µs)...val1(1000µs),val2(100µs),val2(200µs)...val2(1000µs)...val6(1000µs) the destination memory is 60 values of 16 bits. That means I would like to be interrupted every 1ms by MDMA. So I use this configuration (at beginning I would like to test only 2 first values val1 and val2): this is the code to initialize MDMA MDMA_HandleTypeDef hmdma_mdma_channel0_dma1_stream2_tc_0; MDMA_LinkNodeTypeDef node_mdma_channel0_dma1_stream2_tc_1; /** * Enable MDMA controller clock * Configure MDMA for global transfers * hmdma_mdma_channel0_dma1_stream2_tc_0 * node_mdma_channel0_dma1_stream2_tc_1 */ void MX_MDMA_Init(void) { /* MDMA controller clock enable */ __HAL_RCC_MDMA_CLK_ENABLE(); /* Local variables */ MDMA_LinkNodeConfTypeDef nodeConfig; /*
