Hello.I'm working on setting up a brand new Nucleo STM32U5A5Z development board and have some issues.My project is a completely bare-bones default with no security or BSP enabled. The application fails in SystemClock_Config() and enters the error handler. The issue seems to be related to the HSE as SystemClock_Config returns HAL_TIMEOUT here: /* Check the HSE State */ if (pRCC_OscInitStruct->HSEState != RCC_HSE_OFF) { tickstart = HAL_GetTick(); /* Wait till HSE is ready */ while (READ_BIT(RCC->CR, RCC_CR_HSERDY) == 0U) { if ((HAL_GetTick() - tickstart) > HSE_TIMEOUT_VALUE) { return HAL_TIMEOUT; } } }Thanks!

Hi, I'm trying to implement USBPD EPR Source with DisplayPort Alt Mode on a STM32G071. I use the latest https://github.com/STMicroelectronics/stm32-mw-usbpd-core, which seems to support EPR, but I couldn't find any complete examples with a working EPR source. Now I successfully enter EPR mode, and Sink receives EPR PDOs, but can't negotiate any PDO except the 1st. Even SPR PDOs The stack sends REJECT after PE_SRC_NEGOTIATE_CAPABILITY. It works perfectly in SPR mode and can switch between PDOs, but fails the same PDO in EPR mode 1st PDO in EPR mode ACCEPT: 2nd PDO REJECT: How can I debug these things inside the stack? What am I missing? Spoiler (Highlight to read)uint32_t PORT0_PDO_ListSRC[USBPD_MAX_NB_PDO] = { /* PDO 1 */ ( USBPD_PDO_TYPE_FIXED | /* Fixed supply PDO */ USBPD_PDO_SRC_FIXED_SET_VOLTAGE(5000U) | /* Voltage in mV */ USBPD_PDO_SRC_FIXED_SET_MAX_CURRENT(1000U) | /* Max current in mA */ USBPD_PDO_SRC_FIXED_PEAKCURRENT_EQUAL | /* Peak Current info */

Hello,We have procured a STM32U5G9J-DK1 discovery kit. We are in need of the default pre-loaded program that comes with the kit as this will help us to understand how to use Touch display and its other features. We see that this pre-loaded program is not available in the repository downloaded for STM32U5G. Therefore, request you to kindly share it here.With regard,Sudarshan Chaudhary

Hi , I have designed one product with STM32WB55 for BLE and Zigbee concurrency. The schematic design I have followed is the with out SMPS design (LDO mode). VFBSMPS, VLXSMPS, VDDSMPS pins are connected to VDD. Our firmware will scan for BLE devices and it works in Nucleo development board. But not functional in our custom board. With our board it is able to connect upto 4 devices only, but the same firmware can handle up to 18 devices in development board. What will be the reasons for this ?

Hi,I'm using the NUCLEO-U083RC board.I wish to use the TOUCHSENSE library on STM32U083 (or STM32U073) that has the TSC, but STM32CUBEMX 6.16.1 doesn't allow me to enable it.Why ?

I am using STM32CubeMX 6.16.1 to generate project with external Flash loader for STM32N6. When I generate for STM32CubeIDE and build the extmemloader then STM32CubeProgrammer can parse it (the .elf renamed to .stldr). But when I generate CMake project and build with vscode (with STM32 extensions) then STM32CubeProgrammer fails to parse. Compiler/linker removes the StorageInfo structure from output completely. I fooled it to keep it. Now it doesn't fail immediately, but still can't parse any info either.Here's the CubeProgrammer EL list view. First is vscode built loader, second is Eclipse built:I compared the ELF files, Map files, compiler and linker flags. There are plenty of differences and I haven't figured out what exactly causes it. I changed the flags but nothing helped. I noticed vscode uses GCC 14 and STM32CubeIDE uses GCC 13 but tricking vscode to use GCC 13 didn't solve it either. 

Hi,Today I have downloaded STM32IDE. I am trying to develop some projects with my NUCLEO F401RE. I have tried that create a new file from this way but program does not create any .ioc file. Can you help me?Thank you.

I have ordered NUCLEO-G491R to test STANDBY mode power consumption. The power consumption measurements are taken via the PPK2 from Nordic.https://www.nordicsemi.com/Products/Development-hardware/Power-Profiler-Kit-2The steps:1. Take STM32CubeMX example project PWR_SHUTDOWN that is available for the Nucleo board.2. Program the board (ensure the JP5 jumper is at the 5V_STLK position)3. Remove the JP5 jumper because we will be powering the board via the external 3V3 (PPK2) 4. Connect the PPK2 to 3V3 and GND on the board. 5. Start samplingSee the results below:When the device enters STANDBY, the current consumption is measured at about 1.5mA which is way above what is declared on the datasheet.What could be the reason that I cant achieve the declared current consumption for the STANDBY mode via the official example project? I am convinced that measurements of the PPK2 are valid as I have used this board in the past to measure very low currents and it was showing reasona

Hello Sir,I urgently want to have an idea whether due to the change of LCD from HT043C KunJjian to RK043FN48H-CT672B Rocktech in 32F746GDISCOVERY Board, is there any changes in the firmware due to this?I would like to request for early response from your team, thanks for your support in advance.Note: From the post only I got a point that RK043FN48H-CT672B Rocktech changed from HT043C KunJjian, 32F746GDISCOVERY B02 and C01 - what's the differen... - STMicroelectronics CommunityBest RegardsSushant Verma

Good day,I've been working for a little on this and can't wrap my head around what the issue is, so figured I'd post here. As a start I'm doing a graduation project from a computer science education and am working on a project that requires a high speed usb to be implemented on a nucleo h755ziq. There are other pieces in play, but those have been disconnected to try and get this one part to work. To make this work I have the nucleo board and a usb3300. This usb3300 has been put on a board and connects to pins placed on the nucleo. I have quadrouple checked the pins and they are all correct. In CUBEMX I setup the USB_OTG_HS external PHY to device mode, as ill be using it as a device which will be detected by an application later in development. I have also set the middleware up for Virtual Com Port as shown below.My pinout is also setup correctly, but for the sake of detail here is the pinout.I have set up the clock for the stm to 192MHZ due to the other components that will b

Not always, but sometimes syscalls.c file is removed upon generating code for X-CUBE-AI middleware.I'm using STM32N6570-DK board and the version of STM32CubeMX is 6.16.1 for Windows 11.

I downloaded CubeMX and I followed the instructions on the attached Readme.html.I run it by ctrl-click and then select Open to mark the author as trusted, but then nothing happens. Does anyone encountered the same problem? How did you solve it? 

I am having an issue where, when I read the values of the registers continuously, it seems as if the values of the current and power registers have been swapped. After startup, I send the following configuration via i2c:Configuration register write 0x8000 -> to reset the ICConfiguration register write: 0x0037 To continuously measure all values with a period of 1024 ms.Shunt register write: 0x080b -> 0.03 OhmMask register write: 0x0200 -> To enable conversion ready interrupt. Then, when the conversion ready interrupt comes, I read the registers from 1 to 5 at once. From the values read, it appears that the value of register 3 is the current and the value of register 4 is the power. (It looks like they position swapped.)Another interesting fact is that the data read from the power register is exactly half of the actual value. Has anyone else encountered this problem?What could be the cause? Am I overlooking something? Thank you for the support!

Hello,I am designing a board with an STM32H755ZIT6 and want to verify whether my power architecture is safe.Power architecture:Battery inputTwo buck converters:3.3 V buck → MCU VDD5 V buck → LDO + voltage reference → VDDA and VREF+Operating case:For a certain battery voltage range:3.3 V buck is enabled5 V buck is disabledResult:VDD = 3.3 VVDDA and VREF+ = 0 VRelevant datasheet sections:Power supply management (3.5):When VDD > 1 V, all power supplies are independent (except VDDSMPS).Absolute maximum ratings (6.2):“All main power (VDD, VDDA, VDD33USB, VDDSMPS, VBAT) pins must always be connected to the external power supply, in the permitted range.”All conditions appear to be met, but I want to make sure I’m not missing anything, especially since I remember other STM32 families where powering VDD without VDDA is problematic.Question:Is it safe and within spec on the STM32H755 to have VDD powered while VDDA/VREF+ are unpowered, assuming no analog peripherals are used?I would like to co

I am using an STM32L433 with a W25Q128JVSIQ flash.I can read and write data but the W25Q does not seem to respond to the power down command.When I send the power down command 0xB9, reading data from the W25Q should not be possible until the release command 0xAB is sent.  However, I am not sending this release command but can read data from the W25Q, which indicates it did not enter power down.  Below is a scope capture of the power down command and it looks correct...I am using the following driver for the W25Q...https://github.com/mengguang/w25qxxBelow is the function I wrote to power down the W25Q... #define W25QXX_POWERDOWN 0xB9 void w25qxx_powerDown(W25QXX_HandleTypeDef *w25qxx) { uint8_t tx[1] = {W25QXX_POWERDOWN}; cs_on(w25qxx); w25qxx_transmit(w25qxx, tx, 1); cs_off(w25qxx); }I even tried adding a delay (1ms) before the CS pin is raised high after the 0xB9 command has been sent, but it still did not enter power down.With a previous setup I had many

Hi all, Im currently designing my own pcb with a STM32WBA65CIU6 MCU in the UFQFPN48 package.Im doing this for the first time (still gaining all the knowledg needed) and currently ran into the following problem:I'm having trouble understanding the footprint and EDA symbol given for the STM32WBA65CIU6 on the product site and shop. According to those, eg OSC32 are Pins 16 and 17:But according to the data sheet and also in CubeMX the OSC32 should be pin 19 & 20:  Is this not a problem and can be solderd anyway? Also some other pin names are also missmatched :\Thanks for the help :)

Hi,I'm developing a secure boot application for STM32H563ZI microcontroller. I started with a very simple application following ST template code and tutorials like this one: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEMiRoT_Boot_path_on_STM32H563  Everything runs as expected when I try to run my application using the NUCLEO-H5 board. However, this is not true when I do the same provisioning process in my H5 custom board. The only difference I can see between the two tests is that in the custom board I'm using the STLink-V2 programmer, while the Nucleo is programmed by the embedded STLINK-V3EC.Here are some additional points:1) in both cases the provisioning script reaches the end, saying "The board is correctly configured".2) in the custom board, I see the flash full of zeros after provisioning; I checked it with stm32CubeProgrammer3) I have no problems in flashing firmware through stm32CubeProgrammer or stm32CubeIde in my custom board

I’m working with an STM32G473QETx.Does the IWDG window value cause the MCU to reset if the watchdog is refreshed too often (i.e., refreshed too early)?if I set the IWDG window value to something smaller (e.g., 1600), will the MCU reset if I refresh the watchdog more frequently than expected?Any clarification on how the IWDG window works on the STM32G4 series would be appreciated.
