Hello, I'm working with a STM32G0B0CE part.  I believe that the TRM definitions for RCC_CCIPR2->USBSEL are incorrect.I was having trouble with USB, seemingly related to clock selection.  I noticed in the LL HAL headers the following:#define LL_RCC_USB_CLKSOURCE_HSE RCC_CCIPR2_USBSEL_0 /*!< PLL clock used as USB clock source */ #define LL_RCC_USB_CLKSOURCE_PLL RCC_CCIPR2_USBSEL_1 /*!< PLL clock used as USB clock source */#define RCC_CCIPR2_USBSEL_Pos (12U) #define RCC_CCIPR2_USBSEL_Msk (0x3UL << RCC_CCIPR2_USBSEL_Pos) /*!< 0x00003000 */ #define RCC_CCIPR2_USBSEL RCC_CCIPR2_USBSEL_Msk #define RCC_CCIPR2_USBSEL_0 (0x1UL << RCC_CCIPR2_USBSEL_Pos) /*!< 0x00001000 */ #define RCC_CCIPR2_USBSEL_1 (0x2UL << RCC_CCIPR2_USBSEL_Pos) /*!< 0x00002000 */ This seems to indicate that USBSEL should be

I am developing software on the Nucleo-L433RC-P board but have a strange situation when debugging.The first time I debug, the software does not run and I get the following error... Break at address "0x1fff2ce8" with no debug information available, or outside of program code. Break at address "0x1fff2cd6" with no debug information available, or outside of program code. As shown in the screenshot below...

Dear,i used STM32F205RB MCU, could you tell me:1.why the MCU can not wakeup?2.how can i solve it?                                          tin tai

I'm using the AWD (STM32G0B0CE) with the HAL_ADC_LevelOutOfWindowCallback(), which works fine.For not blocking the MCU completely, I'm disabeling the AWD-IT inside the Callback when fired for about 500ms:LL_ADC_DisableIT_AWD1 (ADC1);After the 500ms elapsed the AWD-IT is enabled again:LL_ADC_EnableIT_AWD1 (ADC1);This only works fine for about 2 times:Start -> Fire IT -> DisableIT-> 500ms-> EnableIT -> Fire IT -> DisableIT-> 500ms-> IT stays completely disabled, though enabled again.Any idea what I'm missing?Thanks.

I have received some STM32F405RGT6 microcontrollers that have two circular marks (holes) on the package, while the official datasheet only shows one mark indicating pin 1.Is there an official revision or packaging variant from STMicroelectronics that includes two marks?Additionally, does having two marks indicate that the part might be counterfeit or not authentic?Could you please provide official documentation or images to clarify this

I'm currently implementing very low current measurement electronics, such as Femto Amps.To do this, I'm using the STM32G431CBU MCU. I'm acquiring the output voltages of a float voltage transimpetance amplifier, and I'm taking a running average.My MCU is clocked by a 24 MHz quartz crystal, with the instruction frequency set to its maximum of 170 MHz.But my function is still slow, between 24 µs and 50 µs.float MoyenneGlissante(float valeurI, uint8_t MeanMoving) { static float buffer[50] = {0}; // capacité max : 50 échantillons static uint8_t index = 0; static uint8_t rempli = 0; // Protection : on limite MeanMoving au max du buffer if (MeanMoving > 50) MeanMoving = 50; // Stocke la nouvelle valeur dans le buffer circulaire buffer[index] = valeurI; index = (index + 1) % MeanMoving; // Marqueur pour savoir si le buffer est rempli au moins une fois if (rempli < MeanMoving) rempli++; // Calcul de la

What's the max DC powerline voltage I can use with the X-NUCLEO-PLM01A1 expansion board?  Asked another way, what's the max voltage I can connect to the PLM_CONNECTOR C1?

Hello, @STTwo-32  I am working with the NUCLEO-WB05KZ (MB1801 + MB2032B target). I received two boards from the ST eStore. One board works fine: STM32CubeProgrammer detects the target, and I can erase/flash/debug with no issue. The second board initially connected once, but after flashing a BLE firmware example via STM32CubeIDE, the target MCU no longer responds. Symptoms: ST-LINK is enumerated correctly in Windows (Virtual COM Port visible, target voltage ≈ 3.28 V). In STM32CubeProgrammer: “No STM32 target found” or “ST-LINK error (DEV_TARGET_CMD_ERR)” Cannot connect even when selecting SWD + Hardware reset, lowering SWD frequency, or holding RESET while connecting. Tried with BOOT0 ju

Hi,I have a project with TouchGFX based on STM32N6570-DK.In STM32CubeMX, once I tried to add X-CUBE-AI, I got stuck, and the error is appeared as shown below.What does it mean?Once I removed the TouchGFX Graphic Application, the X-CUBE-AI can be enabled, but the generator removed MX_TouchGFX_Init() etc.Are there any side effects, if I restore the TouchGFX code manually?And I’m curious — why does this limitation exist?Regards!

Hi! My situation is the same as post provided here: https://community.st.com/t5/edge-ai/getting-error-quot-analyze-fail-on-the-ai-model-quot/td-p/55309Is there any solution to this problem? Also, I am using the STM32F407G-DISC1 board with a Mac with M3 Pro Chip.Thanks!

Hello all, I have been working on a keyboard PCB with an STM32F103, and I have started trying to program it with the STM32duino bootloader however, I have been unable to connect to the chip. This is my first time using the STM32CubeProgrammer with an ST-Link V2. I have verified the voltage across several points in the PCB. I have previously used similar designs with STM32F07 chips and had no issues.   Most of the time, I get an error of "No STM32 Target found" and sometimes I get the error "ST-LINK error (DEV_TARGET_CMD_ERR)". I have tried my best to look at past posts on the forum, but none of the solutions have fixed my issue.  I am happy to provide extra measurements and provide more information. Tips on how to troubleshoot this are greatly appreciated. Thank you in advance!   Schematic and PCB screenshot.

I am programming a custom board using STM32L562.

Hello,I have a problem with the configuration of LAN8720A with STM32MP151. My log looks good, but I have a problem when I plug in the wire to the RJ45 port, I get 'Link is down', and vice versa when I plug it out, 'Link is up'.Here is part of my DTS&ethernet0 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&eth1_pins_mx>; pinctrl-1 = <&eth1_sleep_pins_mx>; status = "okay"; /* USER CODE BEGIN ethernet0 */ phy-mode = "rmii"; st,eth_ref_clk_sel; max-speed = <100>; phy-handle = <&phy1>; nvmem-cells = <&ethernet_mac_address>; nvmem-cell-names = "mac-address"; u-boot,dm-pre-reloc; mdio0 { u-boot,dm-pre-reloc; #address-cells = <1>; #size-cells = <0>; compatible = "snps,dwmac-mdio"; phy1: ethernet-phy@0 { u-boot,dm-pre-reloc; reg = <0>; /*compatible = "ethernet-phy-ieee802.3-c22";*/ compatible = "ethernet-phy-id0007.c0f1";

Hello, I want start on a project using the STM32MP157 processor.Working on an embedded Linux OS is a first time for me.  I understand that there is a steep learning curve to get the OS running an embedded system.    Is there any advice for a new comer?  Particularly is there a board that is easy for me to experiment on.   

Hello everyone,I am working with a custom board based on the STM32WB5MMG. On the very first attempt, the FUS firmware update works fine and completes successfully. The problem starts when I try to update the FUS again. Once it has been updated for the first time, any further attempt to re-update the FUS fails.If I delete the firmware and try to flash it again, STM32CubeProgrammer gives the error Error: failed to download image!Even after full chip erase, when I try to re-install the FUS firmware, I end up with the same error.For reference, I am using stm32wb5x_FUS_fw.bin V1.2.0 with STM32CubeProgrammer, I am programming the device via ST-LINK.Has anyone else experienced this with STM32WB5MMG?Any advice or suggestions would be greatly appreciated.Thanks in advance.

Hello,I've got two NUCLEO-STM32H7S3L8 boards and started playing around with those. I created a project in STM32CubeIDE and used the standard template for the board with the generated example data. STM32CubeMX generated the "Appli," "Boot," and "ExtMemLoader" projects, but they seem to have some errors. Here's what I found so far:"Appli"-Project:This line of generated code: #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU Compiler */This led to this compiling error:../Core/Src/eth.c:36:58: error: missing '(' in expression36 | #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU Compiler */| ^../Core/Src/eth.c: In function 'MX_ETH_Init':../Core/Src/eth.c:73:22: error: 'DMATxDscrTab' undeclared (first use in this function)73 | heth.Init.TxDesc = DM

Hey,I am using the stm32wb55rev6 boards as the client and server to send and receive the data.i am able to establish the connection between the server and the client.How can i be able to send the data from the server to the client using the usart1.Do i need to create a new  task in the sequencer using the util _regtask or is there any document related to that?

Has anyone used those BIG KEY button modules before? I’m trying to hook one up to an Arduino, but I’m not sure if I’m wiring it right since the signal seems stuck low. Do they normally need a pull-up resistor or should it just work out of the box?

Peripheral: QSPIBug: Bit 4 of FTHRES[4:0] in the Control Register is not set when written with threshold values in the range0x10 - 0x1F. Works fine for threshold values in the range 0x00 - 0x0F. So, for example, if one writes 0x16 for athreshold level of 23-bytes, the actual value is 0x06 corresponding to a threshold level of 7-bytes.Encountered on: STM32F723IE, STM32F746NG and STM32F767ZIComments: Checked the errata data sheets for the above processors and there is no mention of the bug.Request: Please can anyone confirm that this is indeed an undocumented hardware bug.

Hi,I need to run my application in the external flash, as the size of the internal flash is very less for the stm32h7s78-dk board. I have turned on optimizations as well, but i need external flash configuration. probably XSPI1, XSPI2 what all the things i need to configure. please let me know. it's very urgent.after configuring by referring some samples, i'm getting error while flashing. what can be done Thanks,Harshitha R

I have started using the cube programmer API integrated in a program I wrote access external eeprom via flash loader.I am able to read/write and download file to it without no major problem after I fought some API things.What I think the cube programmer API misses is a call to mass erase external memory. I see that there is an API massErase but it is documented to erase internal flash. (It takes as parameter a name but it is not documented what it means, The param is called sFlashMemName so I really don't understand it's use)I see there is a way to erase sectors but a single API like massEraseLoader (or massErase(FLASH_LOADER) or something like that would be cool). I know the flash loader can full erase a memory because one of the function it must provide is MassErase. I guess it should be just a metter od exposing such API. What I don't really like about the API design is that the readMemory function does memory allocation! Why such design was chose

Dear all,I have the STM32N6570-DK ,MB1860B  version . I'm trying to follow the procedure to flash the .bin files. The programming seems ok, but when I reboot the kit, there's no application... the screen is inactive. However, I can successfully flash the demos stm32n6570-dk-ai-demo-v1-0-0 and N6_OoB_v1.3_single_hex.the link: x-cube-n6-ai-h264-usb-uvc Applicationhttps://github.com/STMicroelectronics/x-cube-n6-ai-h264-usb-uvc/blob/main/Doc/Program-Hex-Files-STM32CubeProgrammer.md  Can you help me ? Cheers Emmanuel

Hi，There are four STM32 MCU on my board. I want to use one JTAG chain to cascade them. So, Could STM32CubeProgrammer software with J-link or ST-link simulator support JTAG Chain to program several STM32 MCU on the one Chain? Thanks in advance!Best regards!Jason

Hi Sirs,                I want to buy an NFC WLC evaluation kit similar to the one shown in the picture I posted. Where can I buy?

The L6920DB temperature rating is not specified in the datasheet. However, it gives the temperature data as Max Tj=150C, Thermal resistance is 180C/W. Based on Tj=Ta+Pd*ThetaJa, if Ta=85C, then the Pd allowed in this temperature is very low. Is L6920DB rated temperature range specified as -45C to 85C?
