Hi,I'm working on the evalboard of the STM32H563. With a plain project I'm able to activate the memory mapped mode of a plugged nor-flash.If I change the project to have Trustzone activated and divided the application in secure/non-secure part, I'm not able to activate the memory mapped mode. The communication to the flash is basically working because I can read the ID. The hal functions don't give any error, so I expect that everything should work.Has anybody an idea what the problem can be? Best regards,Stefan 

Hi everyone, I'm working on integrating the SBSFU (Secure Boot and Secure Firmware Update) into an existing project for a custom board using an STM32U585 microcontroller.At this stage of the project, I am trying to include the SBSFU_Boot (https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/B-U585I-IOT02A/Applications/SBSFU) to my firmware, in order to be able to create a more secure and upgradable environment. My goal is to successfully build and run the SBSFU_Boot bootloader from the ST example using my CMake toolchain, so it can eventually load my existing Secure/Non-Secure application.I have successfully configured CMake to compile the SBSFU_Boot project without any errors. However, after flashing the compiled binary to the microcontroller, the

Greetings, I'm making a project, using a B-U585I-IOT02A board in which I made a Java program that can flash a firmware (using the USB DFU protocol) and also set Readout Protection to Level 1 through the Option Bytes. The program can flash the firmware and set RDP level 1 successfully, but I wanted to be able to flash a firmware, using the USB DFU while having the RDP set to level 1 and I can't. Every time I set the RDP level 1, I can't upgrade using USB DFU, I need to use the STLINK, go to the STM32CubeProgrammer and set the Option Bytes back to level 0, which will mass erase the flash. I know I can't do all this with the STM32CubeProgrammer, but I want to be able to do it with my program (for personal reasons).So the question is, how can I upgrade the firmware using USB DFU, with RDP set to level 1? Thank you! 

Hi all, Can you please give me some pointers how to update the text and needle positions on the custom containers?I have a gui that has multiple images, exactly the same text and gauge positions.  I created the custom container that has different text fields and one gauge.With single gauge and multiple text fields on the same view, I am successfully update these peripherals, but when I create multiple copies of the same custom containers I lost, and I don't know how to access the text fields and gauge's needle.For example:I created customContainer = 2 text fields and 1 gaugeIn then mainView I have customContainer1, customContainer2, customContainer3 and I don't know how to access those text fields and the the gauge.thank you for your time. 

Hello,I have a DCMIPP example application in FSBL that runs fine on an STM32N6570 Disco when loading it with the Disco board's built-in ST-Link. It has a DCMIPP_HandleType Def structure with hdcmipp.Instance that needs to access secure peripheral memory at 0x58002000. It works fine on the Disco kit.I have very similar code on a custom board, using a J-Link debugger. Most of it runs, it communicates okay with the IMX355 image sensor over I2C. The ISP starts up okay. But it fails when the HAL_DCMIPP_CSI_Start() does a check of the hdcmipp.Instance and finds that all of the values are 0 instead of what's in the DCMIPP registers. It can't seem to read or write the DCMIPP registers.I run the same MX_DCMIPP_Init() function on both the dev kit and custom board before calling HAL_DCMIPP_CSI_Start(). The dev kit loads all the register values, but the custom board is stuck at all 0s.I'm only guessing that my problem is due to accessing the secure peripheral memory,

Hi Everyone,I've been working on the N6 kit for a while. Initially, I was able to debug it, albeit with difficulty. However, in my latest attempts, I haven't been able to. I've updated Stlink, the IDE, and CubeProgrammer. I continue to receive the error below. I'm following all the instructions in the Readme. Also, as I mentioned, I've been able to debug it without any problems for about a month. I know that debugging MCUs with external flash drives requires some special considerations. However, when they suddenly stop working after booting, it really makes the development process quite tedious. What should I check? I've eliminated things like the USB cable.

Hello,I bought a NUCLEO-F401RE and the STEVAL-IOM001V1 evaluation board to experiment with the IO-Link protocol. I’m having trouble importing STSW-IOM001 into my project. According to the documentation, it’s supposed to be opened in SW4STM32, which is an older tool. I’ve followed all the instructions I could find for importing it into STM32CubeIDE, but nothing has worked. Do you have any suggestions?

I'm trying to develop a script to flash a secure firmware and set the option bytes on STM32H755. (more on that here https://community.st.com/t5/stm32-mcus-security/flashing-sbsfu-combined-binary-to-stm32h755-with-stm32/m-p/836377#M8786) My specific question here is about the -ob option in the cube programmer CLI.  I'm keen to understand the difference between doing set cube_programmer_cli="C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" %cube_programmer_cli% -c port=SWD mode=UR ^ -w %fw_bin% %fw_base% ^ -ob nWRP0=0 ^ -ob SWAP_BANK=0x0 ^andset cube_programmer_cli="C:\Program Files\STMicroelectronics\STM32Cube\ST

Hello, I am working on a project where I send accelerometer data with the NUCLEO WB55RG in BLE to my phone. I now want to add another NUCLEO WB55RG that acts as a repeater, so it both observes and broadcasts. Is it possible to do this on this type of board, and if so, how?

I'm using the nucleo-H753ZI board to test mcuboot.The setup works and I can successfully run the bootloader and the application in slot0_partition using zephyr sysbuild.However when trying to upload an image I get the following flash write error:[00:00:29.758,000] <inf> mcuboot_util: Image index: 0, Swap type: none[00:00:29.758,000] <inf> mcuboot_util: Image index: 0, Swap type: none[00:00:29.922,000] <err> flash_stm32h7: Status Bank2: 0x00040000[00:00:29.922,000] <err> STREAM_FLASH: flash_write error -5 offset=0x00100000[00:00:29.922,000] <err> mcumgr_img_grp: Irrecoverable error: flash write failed: 12Here is my flash0 dts: &flash0 { partitions { compatible = "fixed-partitions"; #address-cells

Hello, I have no problem storing images in the MCU's internal flash, but when storing images to external flash, it enters HardFault_Handler(). This issue only occurs when calling dynamicGraph Area image, while other images can be read normally. Why is this happening?thanks!

I would need to know how much power does an STM32G0 consume when kept in reset by pulling down the RST pin.Is it specified somewhere?I'm afraid it might be more than what the part uses running a well power optimized software, right?

I don't use the internal Step Down regulator. How should the pins be tied?Should VDDSMPS be tied to VDD and VSSSMPS to GND with VLXSMPS and VFBSMPS left open?OR - should they ALL be left open?Documentation only speaks as if they are to be used - no comments on what to do if not used.

Hello, I have configured a project with CubeMX using a NUCLEO-H7S3L8 with an STM32H7S3L8 MCU.Although everything works, I first need to flash the bootloader and then flash the application.A reset is required to start the app.Using the debugger, I confirmed that the app is running from an external flash drive (PC with a 0x9000000 value).I'm missing the "Build All" option, which allows you to build all three projects simultaneously and start the application after flashing without having to press the reset button. I think so.This is the first time I've used a bootflash MCU, and I'm sure I've missed something.I've attached the IOC file, which only shows a blinking yellow LED.Why do I need to reset the board to start the application? Update 1:There's a "Build All" button in the toolbar that performs this task. But it does this for all projects in the workspace.I usually have several projects in one

Hi,where do I find the full HAL API documentation? Is there a wiki? And also is there a way to pull it up in CubeIDE (I'm not referring to the autocomplete)? Also is there a repository with all examples organised by topic, for example PWM, I2C etc.? Thank you

Hi ST Experts, Iam using STM32H745XIH6 microcontroller, I am unable to debug the dual - core in my application(getting an error - "failed in final launch sequence") when the image that I am using in touchgfx is placed in sdram memory using fmc(0xC0000000).And the dual core is running fine, when the same image is placed in the internal flash memory.I have configured the MPU, then I - Catche and also D - Catche. I am unable to identify the problem with the dual - core, when the image is placed in sdram memory.Thanks in advance...Shivani E

Hello everyone,We are planning to purchase a batch of STM32 microcontrollers via LCSC and, for our internal purposes, we would like to obtain a Test Report from a European laboratory confirming either:compliance of the chips with the manufacturer’s specifications (datasheet), and/orauthenticity of the chips (e.g. using X-Ray or similar methods).We have already contacted around 20 laboratories across Europe, but unfortunately most of them declined, explaining that such requests are outside their scope (they typically focus on EMC/CE testing of finished devices).The models in question are:STM32F103C8T6STM32F407VGT6Could anyone recommend a company or lab in Europe that is definitely capable of helping with this kind of testing?

Hi Sir,We have connected the REXT resistor with a value of 241 Ohms, which sets the current to 80 mA. I would like to confirm whether it is possible to use an external current control circuit to dim the LED.For example, in the case of STP08CP05TTR, with VDD = 3.3V REXT = 241 Ohms, can I control the LED current from 20 mA to 80 mA using an external current control circuit to adjust the brightness?In this setup, I plan to apply a constant 5V as the LED supply voltage.Additionally, I would like to clarify the following:Is this device a constant current sinking driver?Is the current set by REXT the maximum allowable current or the constant current used for sinking?If I apply 5V with 20 mA using an external current control circuit, what will happen? Will there be any issues such as voltage drops or other effects apart fr

Hi,I'm using a SMT32H562ZGT6 uC with RTC pheripheral enabled and clock source from LSE. But HAL_RTC_Init() function returns HAL_TIMEOUT. Investigating I found the method RTC_EnterInitMode returns HAL_TIMEOUT.Clock configuration is performed before calling the RTC initiazlization using The SystemClock_Config generated by cubeMX:void BSP::SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE0); while (!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) { } /** Configure LSE Drive Capability * Warning : Only applied when the LSE is disabled. */ HAL_PWR_EnableBkUpAccess(); __HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW); /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_O

Hi,I have upgraded recently to STM32CubeMX 6.15 on Linux and regenerate code for my STM32G491RE project (that uses iostream). Since this, it gives me compilation errors on missing libc symbols (for example putwc). After investigations, it seems the linker script generated has changed and I wonder if it is expected.Last part of the script has changed from:/DISCARD/ : { libc.a ( * ) libm.a ( * ) libgcc.a ( * ) }to/DISCARD/ : { libc.a:* ( * ) libm.a:* ( * ) libgcc.a:* ( * ) } Could you confirm this is valid and the expected behavior of the new declaration ? Regards
