Solved

I've been trying to get a new project up and running on a custom H743 board, using AzureRTOS for the first time. This board has both USB ports, with FS set up as a device and HS set up as a host, with an external PHY. I have had this same hardware successfully running different firmware with ST's older drivers, and both ports work.It seems like the code doesn't handle having both device and host ports active, even though CubeMX allows you to set it up that way. I run into some issues with both host and device drivers calling _ux_system_initialize, and that seems to trash some of the host's data structures when called by the device's driver code.Either I'm missing something, or the code simply doesn't work for this configuration. I hope it's the former. Are there any code examples of running host and device on the same system? 

Beside enabled it in the Debugger tab:also called LL_DBGMCU_EnableTraceClock();but when calling ITM_SendChar(), the ITM->TCR is still 0.Do I miss anything else?  BTW, I am using the latest STM32CubeIDE 1.18. Thanks.

I have a black pill, but board is green in color, chip says stm32f401ccu6, 44pin.where can i get a pinout diagram for this board, ?only blackpill boards pinouts that I can see are the newer 40 pin boards

Hi,I have been trying to design a double stage single phase grid connected PV Microinverter system.I came across an Application Note AN4070, in which you have designed a 250W grid connected Microinverter. I tried to follow the procedure and design and simulate a system in MATLAB, but my system is not working properly. I have designed the MPPT Block, and it works just fine. I believe the problem lies in the Inverter stage. I have few questions and would really appreciate any help or guidance from your side.1. While looking at Current Control Algorithm, I realized that the alpha and beta components taken for Grid Voltage (Fig. 20) and Current (Fig. 21) are opposite to each other. Can you please help me understand why they are measured in such a way or maybe point me towards a resource that can help me understand the theory behind it.2. I would also like some help in designing the PID blocks for the Current Control Loop. I understand the concept, but I am unable to imp

Hello,Thanks for all of the help so far.  Another question, this one regarding SFI process for the STM32U5 series. In AN4992 section 3.3.1 for STM32L/U/W series, it describes a secure bootloader that is split into 2 parts, one of which is responsible for executing the SFI process. Are these secure bootloader parts pre-installed in system memory by ST as part of your manufacturing & provisioning process?If yes, is the code for this secure bootloader available to ST Micro customers for analysis?When we install our own SBSFU to be used for future OTA updates, does that overwrite and/or disable the SFI capability? 

Hello, According to reference manual/datasheet/ANs, it exists some documents that are pointing out that FDCAN2 is the capable bootloader port for upgrade.In ANs and reference manual, it is specified that FDCAN bootloader mode is available on PD0 & PD1 related to FDCAN1 instance. Can you confirm please? Thank you

Hi,just a quick question to understand the hardware of the STM32MP257 development kit board: there are several ESD-protection components of type HSP051-4M10 used.What is the exact purpose of them, are they therea) because the DK-board is intended to be touched by users and therefore there is some higher danger these users kill that board with some electrostatic discharge when touching itb) because this type of device is recommended to be used in general due to some components being unusual sensitive against ESD (for an example, at the RasPi I think no such protection is used)c) something else?Thanks for sheding some light on this :) 

We are trying to bootload an STM32L443CCT device using CAN bootloader.The documentation for the STLINK V3 details that by using jumper JP7 and CN5 to connect, we should be able to communicate with a device which has been triggered into bootloader mode (by using option bytes only - avoiding having to set or clear any hardware pins to select bootloader). The advantage of this is that we should be able to reprogram devices using the standard CAN interface which each device currently uses, without having to take the device apart to program using JTAG or SWD access.What we are observing is that the T_CAN_TX and T_CAN_RX lines coming out of CN5 are identical, which means that the difference between the signals is essentially nothing. Observing other CAN messages on our bus from other source, it's clear that the CAN_TX and CAN_RX lines should be approximately inverted, yet we are seeing them the same.We've resorted to using the CN7 connector where we need to use a CAN transceiver, we do at le

Hallo Everyone,I am currently trying to retrieve data from a VL53L8CX time-of-flight distance sensor using a NUCLEO-F401RE and an X-NUCLEO-53L8A1 on STM32CubeIDE with the VL53L8CX API. However, I am struggling to get it working and have no idea what I am doing wrong, as I am not getting any error messages from the IDE. I  have never worked on a stm device and this like my first steps, i would be very grateful if someone could help me to solve this issue.Here is my code: #include "main.h" #include "vl53l8cx_api.h" #include "stdio.h" /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ /* USER CODE END Includes */ /* Private typedef -----------------------------------------------------------*/ /* USER CODE BEGIN PTD */ /* USER CODE END PTD */ /* Private define ------------------------------------------------------------*/ /* USER CODE BEGIN PD */ /* USER CODE END PD */ /* Private macro -------------------------

Hi Team,We would like to know how the detection threshold works . There will be 16 detection threshold for 16 blocks (4x4 sensor) . Will the interrupt be fired when any one of the threshold is met or all the 16 blocks detection threshold is met ?Please clarify us on the above query.Regards,Vikaash.K.B

Hello,I'm working on a project that requires the implementation of NB-IoT and to do this I started by testing the Discovery Kit B-L462CELL1, which is very poorly documented. I also noticed that the LBADXX1SC modem used by the kit is now obsolete.Can you recommend a development board from ST Microelectronics that would enable me to do NB-IoT (with zephyr would be a plus)?Thanks in advance.

Hi everyone,I'm working with the LoRaWAN extension for STM32CubeIDE, specifically the LoRaWAN_End_Node project from STM32CubeExpansion_LRWAN_V2.1.0. I need to control some GPIO pins, setting them HIGH and LOW in specific situations. To do that, I want to initialize them to LOW and then toggle them as needed.The problem is that this project does not include a .ioc file, and I'm not sure how to add one to an existing project. If I create a new project from scratch, I do get the .ioc file and can configure the pins easily, but I don’t know how to generate or integrate it into this existing project.Does anyone know how to add a .ioc file to an STM32CubeIDE project that doesn’t have one? Any guidance would be greatly appreciated!Thanks in advance!

Hi all,I used another display with exactly the same resolution with my display for my DK.  If I change the display setup manually for different display's clock settings, I am able to display the image correctly.  Is there a way for me to modify the display's related settings using TouchGFX Designer 4.24.2?Secondly, once the code is generated by the Designer.  I can modify the GPIO/Peripheral/Timers using CubeMX, but once the code is generated by CubeMX, there are folder and files related to TouchGFX were deleted.  I had to go back to TouchGFX and re-generated the code in order for the deleted files to reinstate.What is the correct process should I follow in order for not losing files from generated by TouchGFX Designer?Thank you so much for all of your helps.

Hello ST Community, I am trying to set up SPI communication between two STM32 microcontrollers (two NUCLEO-F401RE boards); one as an SPI master and the other as an SPI slave. For now, I am only trying to transmit only one byte (0x61). For this I am using STM32’s HAL Library, and its functions HAL_SPI_Transmit_IT() and HAL_SPI_Receive_IT.On the slave, the HAL_SPI_RxCpltCallback() and the code inside it (setting a flag) are being executed, meaning that the slave is attempting to receive data sent by the master. However, the data in the SPI receive buffer is always 0x00 (serial terminal shown below; displaying "0" for every SPI receive interrupt occurrence). Termite serial terminal outputting "0" upon every occurance of SPI receive interrupt I need to have the master and the slave operating in Full-Duplex Master and Full-Duplex Slave modes respectively (both with interrupts), however, when setting them in Transmit Only Master and Receive Only Slave, and disabling interrupts

Hi,I'm trying to add external out-of-tree module in developer package. (following wiki)After following wiki, I got error message in board(STM32MP157F-DK2) like this. modprobe: ERROR: could not insert 'kernel_module_example': Exec format error There was a difference with wiki while proceeding according to wiki's explanation.In wiki, the "kernel_module_example.ko" is generated in [install_artifact/lib/modules/"<kernel version>"/extra/].But, my .ko file is generated in [install_artifact/lib/modules/"<kernel version>"/updates/] Is there anything else I need to do to add external out-of-tree module? - Ubuntu version (PC) : ubuntu 20.04 lts- Board : STM32MP157F-DK2- source code version : 24.11.06 (stm32mp1-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06)   Thanks.Regards, Youngjun.

Hi, I am using the STM32U575.In my application, I have to transfer ADC readings to a destination buffer. I have set the DMA source address to the ADC data register (16-bit), and the destination address to a memory buffer start address. The data width is 16-bits or half word, as per the STM32 size definitions.My requirement is that I need to fill the ADC 1024 samples into the memory and after receiving these, transfer them to another buffer, that is connected to a UART, to be transmitted out.However, I need to increment the DMA destination buffer address by 32 bits, after each sample from the ADC, meaning, leave alternate half words empty. The data would look like this in the memory buffer:ADDR 0: fill with sample 1 (16 bits)   - increment DMA destination address by one word (32-bits)ADDR 2: empty - 16- bitsADDR4: fill with sample 2 (16 bits) - increment DMA destination address by one word (32-bits)ADDR6: empty - 16 bits........and so on till the 1024th location

Body:Hello STM32 Community,I’m facing an issue with EXTI interrupts on my Nucleo-G0B1RE board (STM32G0B1RE). The EXTI interrupt doesn’t trigger, even though the configuration appears correct, and I’ve tested both hardware and software triggers. I’ve tried multiple pins (PA0, PA1, PA8, PC13) and created a fresh STM32CubeMX project, but the issue persists. The SysTick interrupt works fine, indicating that the interrupt system is partially functional. I’d appreciate any insights or suggestions to resolve this issue.Problem DescriptionI’m trying to set up an EXTI interrupt on PA0 to trigger on a rising edge. PA0 is configured with a pull-down resistor, and I toggle it by connecting it to VDD (3.3V) to generate a rising edge. The GPIO input works (PA0 detects voltage changes), but the EXTI interrupt never triggers. I’ve also tried forcing a software EXTI interrupt using EXTI->SWIER1, but that doesn’t work either. However, the SysTick interrupt works perfectly, so the issue seems specific

How does the bootloader in the STM32C071 system memory generate its 12-character USB serial number string descriptor (e.g. "205537C24236")?  I notice some similarities between this serial number and the 96-bit unique device ID at address 0x1FFF7550, but overall they look very different.  I'm asking because I would like my firmware to use the same serial number as the bootloader, and being able to use a compact serial number would be beneficial as well.Here are some examples of the 96-bit unique ID (hex formatted, with dashes after every 2 bytes) and the corresponding 12-character USB serial number:1: 7A00-2500-0150-3642-4837-3020, 205537C242362: 7B00-5700-0150-3642-4837-3020, 208737C342363: 7B00-2700-0150-3642-4837-3020, 205737C342364: 7B00-8100-0150-3642-4837-3020, 20B137C34236I looked at the documentation of the unique ID in RM0490, section 30.1, but that documentation was partially incorrect and did not help. 

I'm developing a tool to gang program STM32 products. I'm currently working on the STM32F411 (reference manual RM0383) and the FLASH_CR register SNB field mentions two sectors: user specific sector and user configuration sector. The user configuration sector is documented later in the manual but the user specific sector is only mentioned twice and not elaborated on. At a guess, I'd say its for the OTP region, but OTP can't be erased so its unclear. I've checked other RMs and some mention the user specific sector but don't elaborate on it either. Can anyone tell me what the "user specific sector" is and what I'm erasing if I set SNB to 0b1100 for an erase operation?Thanks,Keith
