Solved

In the last weeks, I was working on running W25Q256 nor flash chip from vendor Winbond with STM32F746 MCU on a custom board. My guideline in this road is ST's how to run QSPI flash video tutorial (5-part video) and of course some genius guys in the community who's helped me a lot to rewrite the functions of QSPI flash (Init, Erase, Write, Memory-mapped). So far functions tested in the Main.c and I can read the pre-written data on the memory. The next step is to generate (.stldr) external loader file and modify Flash.ld file.according to the video tutorial, I added Loader_Src.c, dev_inf.c, and dev_inf.h files to the workspace but there is a little confusion about flash.ld file that contains memory definitions and all other data and text stuff to assign to specific memory (>FLASH, >RAM, >QUADSPI).for the point of concern, I use STM32F746 with IS42S32400F SD-RAM connected with 2-banks to MCU and of-course W25Q256 NOR-FLASH.how to modify flash.ld file to my specific condition and

The graphical representation shows an internal op-amp amplifying the signal entering the comparator's positive input.However, the STSPIN32G4 positive input comparator cannot be an op-amp output unfortunately and is limited to op-amp positive inputs - see Ref. Manual RM0440 ver 9 (Figure 168).This is misleading, because only non-amplified signals gets to the positive input of the comparator.   

Hello!I'm working on an Nucleo-H503RB board and trying to communicate with a LSM6DSO over I3C.I am now able to use ENTDAA to assign a dynamic address to the LSM6DSO.Next, I want to test using SETDASA to assign a dynamic address based on the static address (0x6A) of the LSM6DSO. I followed Getting started with I3C - stm32mcu(4.2 Dynamic addressing using SETDASA CCC section ), but encountered the following issue.Issue:The process stops at RSTDAA and does not continue to SETDASA.I have already verified via I2C that the static address is 0x6A.Question:How can I successfully complete the SETDASA procedure? Full Code:/* Includes ------------------------------------------------------------------*/ #include "main.h" /* Private includes ----------------------------------------------------------*/ /* USER CODE BEGIN Includes */ #include <stdio.h> #include "target.h" /* USER CODE END Includes */ /* Private typedef -----------------------------------

Hi Technical Support Team,I am working with the Nucleo-H563ZI board and would like to enable the I3C interface within the Zephyr environment.Could you provide a minimal sample project or a reference configuration (Devicetree/Kconfig) to validate the I3C host driver and I3C shell?Thank you for your assistance.----------------------------------------------prj.confCONFIG_I3C=yCONFIG_I3C_SHELL=yCONFIG_I3C_STM32=yCONFIG_USERSPACE=yCONFIG_I3C_RTIO=y----------------------------------------------  

I need to implement a protocol using 11110000 as preamble. The protocol is 2-FSK 868.1 MHz, +/-35kHz, 25kbps. According to RM0511 STM32WL33 only supports 01010101 or 10101010 as preamble for 2-FSK. Is it feasible to use the STM32WL33? I am planning to use direct buffer mode.

The board I am using is NUCLEO-H7S3 and I have encountered the following issuesI want to perform continuous and large data sampling using ADC+DMA, but when the collected value reaches 10000, the subsequent values become 0. When I modify the number of collected values to 50000, it stops at 17231 and the subsequent values remain 0. At this point, I am connecting the ADC pin to the 3.3V on the board. I'm not sure where the settings went wrong, please help me.Thank you.    

Hello, I'm using a NUCLEO-C5A3ZG. Not sure it's the right place to write but my goal is to setup the debugger using the STM32CubeCLT_1.21.0 Package under a VSCode environment (already using cortex-debug extension for other projects).I am able to reach the target using the embedded stlink for example with a reading of the flash : /c/Program Files (x86)/ST/STM32CubeCLT_1.21.0/STM32CubeProgrammer $ ./bin/STM32_Programmer_CLI.exe -c port=SWD freq=1000 mode=UR -r32 0x08000000 10 ------------------------------------------------------------------- STM32CubeProgrammer v2.22.0 ------------------------------------------------------------------- ST-LINK SN : 005100353235511237333439 ST-LINK FW : V3J17M10 Board : NUCLEO-C5A3ZG Voltage : 3.29V SWD freq : 1000 KHz Connect mode: Under Reset Reset mode : Hardware reset Device ID : 0x45A Revision ID : Rev Z Device name : STM32C59x/5A3 NVM size : 1 MBytes Device type : MCU Device CPU : Cortex-M33 BL Version : 0x100 Debug in Low Power mode enabl

Hello,I am working on a project where I need to both read and write regularly into the STM32 flash memory. I have some concerns and questions regarding its endurance.First off, I posted a question not long ago about writing to FLASH using ST EEPROM library. I was wondering why upon writing to a variable, it did not effectively write it into flash. This is essentially due to how the library itself works. Hence why I can not really use it to manage flash wearing, because I need the writing to happen precisely when I call a write function due to the fact that my product can be power off at any moment.So going back to the reference manual RM0456, I came upon section 7.3.8 which states:"Each flash memory page can be written and erased 10 000 or 100 000 times. A maximum of32 pages (256 Kbytes) per bank feature this increased endurance of 100 kcycles. Thisenhanced endurance can be used for data storage that usually needs more intensivecycling capability than code storage.Any flash page can be

Hi,I want to create a pin-compatible board to X-NUCLEO-SRC1M1 to further explore USB-C charging, is there a STEP or DXF file available for this or any other X-NUCLEO board that has both the ST Morpho and Arduino UNO R3 connectors please?Kind regards,Al

Created a STM32H743II prj with I2S2 enabled, half-duplex slave receive mode, and DMA1 S0 bounded to SPI2_RX, to work with an ADC in master mode. Can't get data from the ADC ( DMA linked mem area always zero ), while my oscillograph can properly decode the ADC I2S data output pin ( CK & WS pin also connected between the ADC board and the H743 board, and the oscillograph ). In cube, the SDI pin is mapped to SPI2_MISO, PB14. But as a slave, shouldn't the correct SDI pin map to SPI2_MOSI, PB15? So I modified the cubeMX generated code manually, by changing PB14 to PB15 in the I2S2 GPIO initialization sector, and it worked, the DMA linked mem area shows the same value on my oscillograph. Is this a cubeMX bug?

Added "DHCP" in the title to give the context. Using an STM32H7S78-DK I try to set up the network to join an IPv4 network through DHCP. I did set up the board using CubeMX, standard configuration, MPU activated. FreeRTOS + LwIP Removed all other interfaces I don't need. Made sure the Ethernet clock shows 50MHz The LED's on the RJ45 start to blink (Orange LED blinks with packets exchanged) but I get no IP address. digging in the possibilities I added a simple routine to monitor the DHCP advancements. struct dhcp *dhcp_data = netif_dhcp_data(&gnetif); if (dhcp_data != NULL) { printf("[DHCP] State: %d, Retries: %d\r\n", dhcp_data->state, dhcp_data->tries); } this shows I get stuck in state 6: waiting for an ACK -> what could be behind this? can someone share an .ioc file that sets everything correctly in MX?

My situation:Trying to step through/debug a project that will run from the QSPI on the STM32H750B-DK in VS Code (on linux, if that matters). In order to test out the toolchain, I've started with two (separate) workspaces: on has the ExtMem_Boot project, the other the LTDC_Paint demo.What works:A/ Building both projectsB/ Flashing (via tasks.json and STM32CubeProgrammer) the ExtMem_Boot projectC/ Debugging the ExtMem_Boot project via the VS Code debug viewD/ Flashing (via tasks.json, STM32CubeProgrammer and the ExtLoader MT25TL01G_STM32H750B-DISCO.stldr) the LTDC_Paint demo.E/ Launching the debug flow of LTDC_Paint (after modifying launch.json to include the serverExtLoader)What fails:The debugging automatically halts at the Reset_Handler of the startup file, the instruction for loading the stack pointer. But at this point I can't seem to step through it. Even just pressing the run arrow seems to result in a crash, rather than the actual execution.What I find suspicious:The debug consol

This error pops up everytime I try creating a new STM32 project when downloading the selected files during the first stages of creating a project. My internet connection is fine and this wasn't an issue some weeks back with the last project I created. Any assistance on this issue from anyone will be very helpful because I'm a quite a newbie to CubeIDE. Thanks.

Hi!I'm building a device using a STM32U31xx, connected to a Network Chip via I²C (PB6/7) and 2 GPIOs for Reset and BOOT0 Pin. The intention is to have new firmware downloaded onto the network chip, and flash new firmware to the STM32U031 via the system bootloader.I power up the system to invoke a power up reset on the ST device, I immediately flash firmware and ask the chip after another reset cycle for the new firmware version to confirm the new firmware was flashed.The behavior I observe is the following:- if the STs Option Byte nBOOTSEL is 0, the process works just fine, very reliably.- if nBOOTSEL is 1, the process fails even if I mass erased the STs flash memory entirelyThis is contrary to my understanding of AN2606 Table 2, pattern 11, that states that the empty check should start the system bootloader no matter the state of nBOOTSEL bit or BOOT0pin.I intended to have the ST chip flashed on production without previous intervention into the STs option bytes (nBOOTSEL is 1 on deliv

Hello,I am writing this because I am unable to enable the SAI on this development board. The strange thing is that I actually managed to enable it before and it was working correctly. However, while implementing another feature, I switched branches and worked on a different GitHub branch for some time. When I came back, I noticed that the SAI was no longer starting.At first, I thought I had made a mistake in a commit, so I created a completely new project where the only goal was to start the SAI. Even though I believe all the steps are configured correctly, the MCK clock never starts, and the MCKEN register bit never becomes enabled. I am attaching screenshots of the SAI registers below. As shown in the screenshot, the SAI is enabled, but I cannot see any clock output on the oscilloscope. As I mentioned before, what confuses me the most is that two weeks ago, using the exact same development board, I was able to make it work correctly.I tried adding the following line inside the M

Hi all,I'm looking for recommendations on eMMC chips that are known to work reliably with the STM32H743 via SDMMC1 in 8-bit mode.I've gone through a number of threads here and put together what I've found so far:- Micron 4GB (MTFC4GACAJCN) — comes up often, though some posts mention HAL misreading certain CSD fields (appears cosmetic rather than functional)- Kingston 4GB — confirmed working with SDMMC1 + FatFS + FreeRTOS, corruption reports seem tied to FatFS rather than the chip itself- Samsung KLM series — functional but VCCQ voltage negotiation adds complexity- Kioxia THGBMDG5D1LBAIL — 153-ball WFBGA, eMMC 5.0, fewer reports but looks promisingHappy to keep things simple — 3.3V on both VCC and VCCQ, no need for HS200/HS400.Would love to hear from anyone who has had long-term success with a particular chip, or any that are worth avoiding. Any layout tips for the 153-ball WFBGA package are also welcome.

I'm using an STM32H7S78-DK with TouchGFX and FreeRTOS. I would like to limit the framerate of the target to 30fps but withouth reducing the LTDC frequency.Basically having the VSYNC fired at 30fpsI've already set the  ((touchgfx::HALSDL2*)&hal)->setVsyncInterval(33.333);In the simulatorIs there a way to force it on the target?

Is there any utility in the holes and silkscreen circles around the TFBGA225 on the NUCLEO-H7S3L8?  It appears to be the same pattern on the Discovery board, suggesting it might be for BGA placement or maybe a heatsink. Edited to put the image in-line for better visibility

Hello Team,We are using the internal SMPS configuration for the core power supply. However, the power-up sequence does not specify the timing requirements for the different stages.Could you please provide the timing details for the following? What should be the time duration for the PWR_ON signal to transition from low to high while VDD and VDDA18AON are rising (Step 1)?After PWR_ON goes high, what is the required time duration for VDDA18PMU / VDDSMPS to rise (Step 2)?What is the exact meaning and function of the SDEN signal?Are there any additional considerations or recommended guidelines to be followed during the power-up and power-down sequence? Thanks 

Hi, hope you doing good,In our design, we are using the ST60A3H1C1CCEPY3 controller. please clarify if there are any layout restriction or keep-out zones around the controller where other peripherals should not be placed.Thanks,

Hello, I am using an **STM32 NUCLEO-N657X0-Q** board with the **B-CAMS-IMX camera module**. Originally, the board was working correctly. In **DEV BOOT mode**, I loaded and ran my AI model, using the B-CAMS-IMX camera sold by ST. The board connected normally to my laptop, and I was able to confirm that the AI application was running correctly by viewing the camera output and the AI object detection result on my laptop. I also changed the BOOT pins and confirmed that the same AI application worked correctly in **Flash Boot mode** as well. After that, I wanted to test whether the board could run from an external power supply instead of being powered through ST-LINK. So I changed **CN9 from 1-2, STLK power, to 5-6, VIN power**, following the description in the official NUCLEO-N657X0-Q documentation. Then I applied **7V from a DC power supply to the VIN and GND pins** of the NUCLEO-N657X0-Q board. I carefully checked the polarity and connected VIN and GND correctly. When I supplied 7V throu
