Has anyone successfully used this Simulink STM32 guide to write to an SD card? I am trying to run a simulink model on a Nucleo-F767ZI and write the output to an SD card. I have tried to follow the directions, but it is not working. The model can compile and run on the board, but when I check the SD card, it is still empty. I have tried different clock speeds, 1-bit and 4-bit modes, but nothing seems to work. I scoped the clock signal, and it seems to be at 400 kHz, which is indicative of it being in the initialization stage. Does anyone know what may be wrong? Thanks!  

I intended to write a wrapper to access the memory section of the M24512 part. I began with enumeration using the device identification code, but instead of receiving I2C Family as 0xE0, I got 0xFF, I need to understand what went wrong. Additionally, when I write a byte to memory and read it back, it still shows 0xFF, please find trace logs attached, appreciate your quick reply.

 Hi, I need to read 8 channels through the ADC in DMA circular mode, to check the channel status readd I put all channel to GND from nucleo board and two channels (ADC_IN2 on PA2 pin and ADC_IN3 on PA3 pin ) doesn't give me the correct data, you can see in the image all channels to 0 except this two.I try change the wires but isn't the problem.All code is generated from MX tool. Can anyone tell me why these two channels are not working?Attached is the entire project.This is the main file:/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2025 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this

Hello there, I see in the datasheet for the STM32C071Rx that the version N (with VDDIO) marks PD4 as supplied by the pin VDDIO in the figure 10:But the table 12 doesn't marks it as a pin supplied by VDDIO but VDD instead:Which is true? VDD or VDDIO?Thanks

I tried the Cube BLE exemple to tried to set the device name for the advertising message but I can only see the advertising address. How could I do to set the name? /* Update device name */ ret = aci_gatt_update_char_value(service_handle, dev_name_char_handle, 0, sizeof(device_name), device_name); if(ret != BLE_STATUS_SUCCESS) { PRINTF("aci_gatt_update_char_value() failed: 0x%02x\r\n", ret); return ret; }

I've been trying to build compatible Android modules (.ko) for my STM32MP25F7-EV1 running OpenSTDroid Distribution. I've successfully built these modules, but I cannot enable them with the `insmod` command because they're incompatible.insmod: ERROR: could not insert module btusb.ko: Exec format error I ran `strings btusb.ko | grep vermagic` and it looks like the `btusb.ko` is using a slightly different kernel version than the target's kernel version (6.1.78-00024-ge4076639eb90 for module v.s. 6.1.78-00024-gf31b8a21afa8 for kernel).vermagic=6.1.78-00024-ge4076639eb90 SMP preempt mod_unload aarch64 __UNIQUE_ID_vermagic330 __UNIQUE_ID_vermagic330I don't understand where I'm going wrongly.

Hello friends, Hardware DetailsMCU: STM32N657Z0H3QConfiguration: Custom PCB designBoot Mode: Attempting USB Boot (BOOT0=HIGH, BOOT1=LOW)Power: 1.8V system, SMPS for CORE (as per datasheet)Problem DescriptionI've designed a custom PCB using the STM32N657Z0H3Q and I'm facing issues getting it to enter boot mode. When I connect the board to my PC with BOOT0 pulled HIGH and BOOT1 pulled LOW, the USB device is not recognized by STM32CubeProgrammer.I've verified all power rails are providing the correct voltages. I've also tried multiple cables and USB ports to rule out simple connectivity issues.Additionally, I attempted using ST-LINK for programming but that's failing as well, which makes me suspect there might be a fundamental issue with my circuit design.What I've TriedConfirmed all power supplies are providing expected voltagesVerified boot pin configurations (BOOT0=HIGH, BOOT1=LOW)Tried multiple USB cables known to work with other devicesChecked connections against reference docum

Hello,I am experiencing an issue with STM32CubeMonitor on Windows 11 where some nodes, including acquisition out, are marked as "not found" and cannot be used.I have found similar reports from other users:https://community.st.com/t5/stm32cubemonitor-mcus/cubemonitor-acquitions-installing/td-p/660215https://community.st.com/t5/stm32cubemonitor-mcus/missing-acquisition-nodes-on-macos/td-p/644151I have tried the suggested solutions, such as running stlinkserver, but the issue persists. After starting stlinkserver, is there any additional setup required?Has anyone solved this issue using a different approach?Are there any additional steps required after starting stlinkserver?Environment:OS: Windows 11STM32CubeMonitor Version:1.10.0 

Hey all,I was just reading out the new release of the X-CUBE-Audio-Kit and it says:Configurable latency mode and audio buffer sizes adjustable down to fractions of millisecondsDoes anyone know the lowest latency that can be achieved?I'm looking to possibly replace a codec that is doing my DSP - need to be able to do a a 5 to 8 band EQ, compression and volume control as well as mixing 2 stereo signals, but need it to be less than 0.5ms.Is that achievable with what the X-CUBE-Audio-Kit provides? Are there any low latency examples?

Hi all,Could you please tell me if the temperature sensor of the LIS2DW12 is used to correct the acceleration sensor?Thanks all,

I'm trying to achieve a modular design via i3c. All targets and controller is stm32h503cbt6. The targets hot join the bus one by one. After receiving the dynamic address, targets can send small data to controller during IBI request. But only the first 4 of them can send data successfully. The other ones only get NACK.from the controller during IBI.I'm suing HAL_I3C_Ctrl_ConfigBusDevices() to store the dynamic addresses. Later I found it can only support up to 4 dynamic addresses. The function writes the addresses to hi3c->Instance->DEVRX, which is an array with a length of 4.Is there any way to store more of them?Any help and suggestions will be much appreciated! 

I get an error message when I try to connect with the STEVAL-WLC38RX evaluation board using STSW-WPSTUDIO.  I am using v2.7.2 of WP Studio.  See error message attached.

and in the FAIL.txt "The interface firmware FAILED to reset/halt the target MCU" When I connected my F4 Discovery card to my computer, the card's folder opened in front of me and in it, apart from the usual files, another file called FAIL.txt, which I saw for the first time. Inside the file, the error “The interface firmware FAILED to reset/halt the target MCU” was written.I tried to enter debug mode and this time I got the error “Failed to execute MI command”. When I searched this situation in this community, none of the solutions worked for me. I did St-link firmware update via CubeIDE, CubeProgrammer and ST-link utility. Although I did update via ST-link utility and cube programmer, it does not allow me to enter the contents to do a full-chip erase. When I asked Chat-Gpt, he scared me by saying that my card might be burned. But I did not do anything to burn the board.I connected the PA0, PA1, PB2 and PB10 pins on the board to the channels of the logic analyzer and connected the

I´ve bought a new ST-Link V2 from a reputable electronics Vendor (Reichelt, Germany) to connect to my Cartographer 3d scanner for a 3d Printer with an stm STM32 chip. It is connected correctly as far as I know. I cannot establish any connection. I've also tried another board that didn't get recognized, so I think my ST-Link is broken, or am I overlooking something here? They both sometimes show as SN: 31FF710631315436290343, but as soon as I try to connect they just vanish. Is the ST-Link broken, or am I missing something since this is my first time doing this?

Hi, I'm using ST for the first time, I have a NUCLEO-H753ZI, and I cant find in the user manual if it is possible to program an external MCU using the Embedded STLINK-V3E, can someone help me with this ?Thanks

I am currently designing a board that uses the STM32WL55JCI7 LoRa functionality. I am currently using the AT_SLAVE firmware provided by ST for testing. I am currently trying to Transmit a signal through the Antenna on my board but no signal has been been coming through. After some investigation I have noticed that the VR_PA voltage is stuck at 0V. I am trying to transmit in Low Power mode, and the voltage on the other pins is as follows:VDDRF = 3.3VVDDPA = 1.55 VThis software has worked on a different variation of my board so I do not believe it is a firmware issue. I am trying to figure out why this particular board is not working. 

I was a bit surprise if I read a characteristic witch is more 22 bytes long it conduct to more than one read permit events on server-side and as many read response on client slideit's surprised me because limit carac buffer length is 250 byte max in config by defaultis there a way to enlarge this ?? (server or client side or both ?)it would not a be a big deal if I can determine on server-side when carac is completely red but I can't get any idea where reading is regarding total bytes size of CARAC according to § 4.7.6 Evt_Blue_Gatt_Read_Permit_Req in https://www.st.com/content/ccc/resource/technical/document/user_manual/6d/a1/5b/6c/dc/ab/48/76/DM00162667.pdf/files/DM00162667.pdf/jcr:content/translations/en.DM00162667.pdf the event message should be grouping but in stm32wpan middleware core ble_def.h message structure dont include datalen and it looks that length of encapsulating message is sized accordingly typedef __PACKED_STRUCT { uint16_t Connection_Handle; uint16_t

Hi developers.I have the same issue as many others, which has been posted already 4-5 times and marked as "solved" in some of them, but it is not at all the case.The CubeMX on launsching shows the first screen (splash) and then disappears.It worked a couple of times after intallation, then again after de-installation/reboot/re-installation/reboot.Watching the Task-Manager it shows a process called "OpenJDK Platform binary" which starts at high CPU and ends up to 0% but with around 200MB RAM reserved. And this can take place many times, collecting a bunch of idle/useless processes. I run it with Windows 10, latest version of JAVA and CUBE at this moment, but with a previous version on both I used to have the same issue.While unistalling, I try to find every single file I can, so that I delete each trace manually, but every time I re-install it, it still "knows" which was my last opened projects and which uC I use. Maybe ST can see it a bit seriously the topic. I suppose I am not th

I was trying to write a small firmware to keep the LD9 Orange LED steady ON, instead of blinking in STM32CubeIDE. I could able to flash into CM33 core using the debugger and able to debug. When I disconnect debugger, it still remain ON.But once I reset the board, the CM33 firmware is gone and LD9 again started blinking, as if my firmware is over written.Any solution?

Hi all,I am looking for advices to implement my GUI.  I have screen 1 with all the widgets. On this screen by default has:1. The texts for Hours:Minutes:Seconds and a button to switch to setting screen to set the count down timer.2. The switch mode button, to switch the timer 1 to timer 2.Timer 1 has different texts and looks vs. timer 2.The rest of the widgets on screen 1 stay exactly the same.Currently, I have a solution buy copy exactly the same screen 1 and just replace the timer texts and button only, and using switch mode button to switch back and forth the screen 2 to screen 1 and vice versa.I found this is wasting the memory resource and additional coding to handle different screens.Question:Is there a way I can use only screen 1 and change texts and button between timer1 vs. timer2?

Hi,I'm currently working with the STM32G491RET and using the NUCLEO-G491RE evaluation board. I need to check whether the device enters boot mode using the BOOT0 pin and NRST. From my understanding, to enter boot mode, BOOT0 should be driven low, and NRST should be toggled (low to high). I connected the board to my PC via USB (ST-LINK) and tried entering boot mode, but it only resets the board and restarts the existing program, printing debug logs as usual. Initially, JP3 (which connects the ST-LINK reset to the MCU reset) was shorted. The hardware team has now removed that connection. After this change, when I attempt to enter boot mode, no logs are shown. How can I confirm whether the device has successfully entered boot mode?One more clarification is needed. If i get a fresh board, just BOOT0 pin and NRST enough to enter bootmode?

Hi ST:I am devloping the STM32MP131c  with yocto packageEverytime after i modify the dts using devtool, i need tobitbake st-image-coreand flash all image with stm32cubeprogramming tool There is a ethernet on my boardIs there any faster way to help me verify my dts modificationMaybe compile the dtb only and scp into DUT or compile bootfs only and i can only flash the bootfs partition Thank you

Hi,I'm curently working on a STM32H745i-disco and need to implement a uboot on it. It doesn't seem to be natively supported. I would like to know if there is a port on going or at least if you have somewhere the linux/uboot device tree for this board. Found it for Zephyr but not Linux / uboot.Thanks in advance.
