Hello,I have a Nucleo-WB09KE.I cannot connect normally to the Board using the Programmer. Only Hotplug is working ?!?. Any idea ?What I already tried: - Connect with hotplug and mass erase. → Flash is blank. - Update the Programmer and the Driver to the latest one. - connect via mode ‘normal’ ’under rest’ failed  

I have the timing budget set to 56ms. Have histogram merge turned off, and histogram max size set to 1.I also have an IMU on board. I have also enabled Phase cal patch power. The following is the setup.I am having trouble getting returns above 1.2metres, and is there any way of estimating the timestamp with higher fidelity. At the moment I am just taking the mid-point from when it starts ranging to when we can load the sensor. Its not using a GPIO pin, its using the blocking getMeasurementData function, we have instrumented that poll and have included that into the timing measurement. Just want to know if theres any tricks we can do to get it comfortable returning 2+ metres, there are 16 sensors pointing radially outward. The sensor has slow  and fast dynamic motion that it undergoes.

Trying to build a NUCLEO-C562RE project under IAR 9.60.4. Included with the output is an folder, IDEs_patches/EWARM and a readme,md outlining how to add support for the new MPU. But the patch file referenced in it is no where to be found. Searched my local drives, ST’s site, ST’s Community, ST’s github but  can’t find “STMicroelectronics.stm32c5xx.2.1.0.iar.zip”I’m glad ST has decide to distribute a patch so I don’t have to upgrade to the latest IAR every time a new CPU comes out (my company tries to use a consistent version across projects) but without the patch file, IAR does not recognize the C564 as a target.

Hello, I have a kind of general question about the usage of interruptions and memory barriers.Because of the pipeline architecture of the processor, it is recommanded by ARM (https://support.arm.com/documentation/dai0321/a/ ) to use DSB / ISB instruction when enabling disabling instruction. The guide focuses (amongst othr cases) on the NVIC operations. The CMSIS functions __NVIC_DisableIRQ and __NVIC_EnableIRQ look to respect the guidelines.However, I’m wondering if such practices should be applied when enabling/disabling the peripheral interrupt (typically via the enable interrupt register) ? Same with the RegisterCallback functions avaialble in the HAl libraries. Regards. 

Does STEVAL-ESC001V1 evaluation board support 6 step ?.it already supports FOCif so any idea how to implement 6 step in steval esc001v1 

Hello,I have a project that uses I3C to connect a Nucleo-C562RE with an STM32C542CCT6 MCU. The setup was working fine with HAL 2.0.0 but it does not work in 2.1.0. I generated the code with MX2 and I observed that it is identical to the code in the private_it_controller example code. I stepped through the mx_i3c1_init function and I noticed that the moment the GPIO for SDA and SCL are enabled, the I3C clock (SCL) is turned on (visible on the oscilloscope) and does not stop. I don’t see how this could be correct. When I try to start DAA it fails instantly (the error callback is invoked) and the SDA line never changes state (it stays HIGH after reset).Can someone help with this issue?Thank you,Gil

When building in STM32CubeIDE 2.1.1, and targeting an STM32F303K8,Project properties C/C++ Build Settings MCU GCC Compiler Miscellaneous Near the bottom, observe a checkbox for -mtune=cortex-a35.This option really does have effect in the gcc command line, and that really does significantly alter the compiled machine code.But… why is this allowed in the UI? Why would this tuning option appear specifically for the A35, when the STM32F303K8 is an M4? By default, the makefile does correctly add -mcpu=cortex-m4.

Hi,Do enabling BDU also protect temperature data registers from getting refreshed while reading the data? Or is it just for accelerometer data registers? BR,KJ

Hello ST Team,Could you please review the attached ST25DV60KC NFC antenna design and provide any recommendations regarding the antenna design, schematic, and PCB layout?Any comments or best practices before PCB release would be greatly appreciated.Thank you for your support.

Despite the peripherals are callable, the code preview from STM32CubeMX2 does not call the init functions of the peripherals.What is the trick to get this done ?We also see in the HAL common settings, the option to toggle generated vs callable is not selectable.Is this something to do with the older version of STM32CubeMX2 v1.1.1 and STM32CubeMX2 v1.0.0 ?Please suggest 

In order to meet the USB suspend mode maximum current requirement I am using Stop mode once the suspend has taken effect. I have no difficulties getting it to go into Stop and the current consumption falls to well below 2.5mA, as required. My problem is that it won’t wake up following either a host-induced wakeup, or due to a remote wakeup that I have set up on my product’s buttons.Host-induced wakeup does cause the current consumption to increase, but it doesn’t get going again. Remote wakeup has no effect whatsoever.If I replace my HAL_PWR_EnterSTOPMode call with a simple __WFI() it wakes up from both without any difficulties, so I know the EXTIs are all set up correctly etc.So what’s wrong? I actually know the answer (after days of head-scratching) and will post it as an answer to my own question so that this is documented and will hopefully save others similar frustration. Although I’m using a C0 with USBX, I imagine this applies to all MCUs.

 Hello ST Team,I am working  on the STM32MP257F , using OpenSTLinux 5.0.17 and the ST TSN switch stack v6.I would like to confirm whether the TSN Ethernet switch is officially supported on the STM32MP257F-DK boardNOTE:I understand that the DK board has only one externally accessible Ethernet port and that it can be used as a TSN endpoint. I have enabled the TSN switch, and the following interfaces are available:lowlan0end0sw0p1sw0p2sw0p3sw0epWith the TSN switch enabled, the switch interfaces are created and sw0p1, sw0p2, and sw0p3 are visible. I have connected an external PHY to sw0p3.root@stm32mp2-e3-d2-99:~# ethtool sw0p3Settings for sw0p3:Supported ports: [ TP MII ]Supported link modes: 10baseT/Full100baseT/Full1000baseT/FullSupported pause frame use: NoSupports auto-negotiation: YesSupported FEC modes: Not reportedAdvertised link modes: 10baseT/Full100baseT/Full1000baseT/FullAdvertised pause frame use: NoAdvertised auto-negotiation: YesAdvertised FEC modes: Not reportedLink partner

I am currently working to redesign one of our products to include Bluetooth communication for remote control. For this, I am targetting the STM32WBA23.Given that the PCB is mounted inside a solid, cast-aluminium housing, I will need to put the antenna on a seperate board and connect it with a cable to the main PCB.My question now is: Where do I put the tuning components? Do I place these on the main PCB, close to the controller, or do I put them on the antenna board?Or maybe it doesn't actually matter. I would appreciate any comments and directions by those more RF savvy than me.

The "Discover" button on the STM32CubeProgrammer fails to connect to my my STM32H56x (STM32H562VGT6) in the Closed state (0x72). The instructions I followed for enabling password security are in the "How to enable RDP-like product state flash protection in STM32H5 microcontrollers" post. No errors came up in following these steps. To summarize my steps:1. Installed STM32CubeProgrammer and STM32TrustedPackage Creator2. Generated OBKey and password.bin files from DA_ConfigWithPassword.xml 3. Set PRODUCT_STATE to Provisioning (0x17) and executed "Start Provisioning" with the generated .obk file4. Set PRODUCT_STATE to Closed (0x72)  The issue arises when going to perform a regression. In the Debug Authentication window, clicking the "Discover" button does not prompt me to select a password file and throws an error that states "Failed to communicate with target !". The Debug Authentication sequence does not start. The same error occurs whether or not my ST-Link

The product page and datasheet only mention BLE Core 6.0 but don't call out channel sounding support explicitly like other BLE features. Is it actually supported?

Hello,I'm prototyping a custom board equipped with a WBA23KE and developing its software.Since this custom board doesn't have a 32kHz crystal, I modified the code based on BLE_p2pServer, referencing the description on the following website.LSEクリスタルなしでSTM32WBA上でRFアプリケーションを動かす方法 - stm32mcuHowever, the HAL_RTC_Init() function on line 615 of the attached main.c fails and goes into ErrorHandler().How should I modify the code?

ContextI'm finalizing a 4-layer FR4 board with an STM32WBA62CIU6 (2.4 GHz BLE), and I'm not 100% sure about the best way to make the Bluetooth matching/tuning easier.I first built a board with a PCB antenna identical to ST's (following the exact shape shown in application note AN5129) and a 5-element Pi network, as shown in one of the circuits in ST's application note AN5948:1​​​​​I then used a VNA, connecting at the pad where the STM32 would sit, and tuned the Pi network components so that the Pi + antenna would present an impedance of 30 + j2.5 Ω — the output impedance of my chip at 10 dBm (the power I want to use):2My tuning workflow was: measure with the VNA → export the result → load it into the SimSmith "Load" → place components in the simulator to get a sense of which values to use in real life. However, when I placed the real components, the result was quite different from the simulator — so different that I ended up unable to complete the tuning.Current setup / measurementsSta

Hello,the observed bug is the following.We are using STM32L433RC and generating some code from CubeMX using low-level libraries. We are currently evaluating precision of the hardware clock compensation, when using internal MSI RC oscillator with external crystal of 32.768kHz connected, and PLL mode (in order to do the compensation) enabled.The sequence generated by the CubeMX is the following:void SystemClock_Config(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_4);   if(LL_FLASH_GetLatency() != LL_FLASH_LATENCY_4) { Error_Handler(); } LL_PWR_SetRegulVoltageScaling(LL_PWR_REGU_VOLTAGE_SCALE1); LL_RCC_MSI_Enable();   /* Wait till MSI is ready */ while(LL_RCC_MSI_IsReady() != 1) { } LL_RCC_MSI_EnablePLLMode(); LL_RCC_MSI_EnableRangeSelection(); LL_RCC_MSI_SetRange(LL_RCC_MSIRANGE_11); LL_RCC_MSI_SetCalibTrimming(0); LL_PWR_EnableBkUpAccess(); LL_RCC_LSE_SetDriveCapability(LL_RCC_LSEDRIVE_LOW); LL_RCC_LSE_Enable();   /* Wait till LSE is ready */ while(L

Hi,How does the 3 wire SPI mode work in ISM330DLC? How is the physical connection for this mode? Are there any changes to be made in register configuration other than enabling SIM bit in register 12h?Regards,KJ

Missing Makefile export capability. Missing option to export only minimum necessary files. Unfortunately this leads to bloated projects. The previous version of STM32CubeMX have these features. Clean and self-contain and not bloated project was the main reason to use STM32 in our company.

Hi.I'm trying a simple ping application with my board that contains the H743 microcontroller. I am following the instructions in Adam Berlinger's example. But I can't get ping. I connect my computer to my board via ethernet switch. My computer's IP is 192.168.2.5. But it can't reach to my board. When I try to send UDP packet, I can see the Ip adresses of target and destination(via WireShark software). But I can't see the "Hello UDP message!\n\r". IPs are manually setted. H7 board and computer connected via ethernet switch hub. I added a breakpoint to "void ETH_IRQHandler(void)". After the initial power-on, the system reaches the breakpoint twice even when there is no ping command on the Ethernet port. But when i send ping commands, nothing happens. I can reset LAN8742A PHY via GPIO.  /* Initialize all configured peripherals */ MX_GPIO_Init(); /* USER CODE BEGIN 2 */ HAL_GPIO_WritePin(ETH_RESET_GPIO_Port, ETH_RESET_Pin, GPIO_PIN_RESET); HAL_Delay(50); HAL_GPIO_WriteP

Hello ST Community,We are currently developing a custom board using the STM32N657X0H3Q MCU with the internal SMPS configuration.We have assembled 5 prototype boards, and before applying power to any of the boards, we measured the resistance between the VDDCORE_0V8 rail and GND.We observed a relatively low resistance on all 5 boards, with different measured values:Board    Measurement Point    VDDCORE_0V8 to GNDBoard 1    TP16 / TP24    22.32 ΩBoard 2    TP16 / TP24    25.9 ΩBoard 3    TP16 / TP24    20.9 ΩBoard 4    TP16 / TP24    12.8 ΩBoard 5    TP16 / TP24    16.2 ΩImportant: None of the boards have been powered up yet.The VDDCORE rail is generated using the STM32N657X0H3Q internal SMPS, with an expected VDDCORE voltage of approximately 0.8 V. The VDDCORE pins are connected according to our schematic, and the internal SMPS pins (VDDSMPS, VLXSMPS, VFBSMPS and VSSSMPS) are also connected as shown in the attached schematic.We are concerned about the low resistance readings, particularl

I have setup STM32 VSCode extension on my PC and it is amazing. The only problem that I have encountered is that it is not possible to run the code without debugging. I removed the "runToEntryPoint": "main" line in launch.json. But every time I launch the code it attaches a debugger. How can I simply run the code without debugging? Thank you,Damiano
