Goal boot from a Quad SPI flashI shouldn't need to change any OTP settings.  Any sNor flash chip connected to XSPIM_P2 that can operated in single spi mode can be booted off from? From my understanding if we want to make a dev board and use a different external memory that is not Octo SPI flash but just Quad SPI flash we shouldn't have to change any of the OTP registers.  SinceIn sNor flash it starts in single spi modeThen in your FSB you can configure the SPI to your given device(From my understanding)There are no OTP registers for Nor flash settingsThese are all setup in the ROMChanging OTP 11 bits (5-8) would force us to loose the ability of Dev up (From my understanding) Most of this info is from theHow to proceed with boot ROM on STM32N6 MCUshttps://www.st.com/resource/en/user_manual/um3234-how-to-proceed-with-boot-rom-on-stm32n6-mcus-stmicroelectronics.pdf  No boot source is programmed in OTP default source is serial NOR No configurati

I have a STM32N6570-DK and i can't seem to program it any more.  I tried it in both the STM32 programmer gui and terminal application.  So i can connect to the device read and read the flash but i can't seem to write to it any more.  I can't even erase the flash.  I have another  Boot 0 = 0 (L)Boot 1 = 1 (H)

Hello,I am working with the STM32H7B3I-EVAL boardI have I2C slave model work properly the default adress used by contoller given in schematich work on 84 aand 85 adress but the other peripheral adress not get give me the roadmap for the coding of communication protocolsI2C Slave Address detect. how can i code done for other peripherals using mfx expander give me solution  didnt solve the issue.Thank you 

Hi everyone,I’m working on a battery monitoring prototype using an STM32F303. I’m measuring multiple analog voltages using the internal ADC with DMA. The ADC readings fluctuate by ±20 counts whenever the PWM output for the buck converter is enabled.I already added averaging in firmware, but the noise is still visible. The analog input traces are routed near the switching MOSFET area on the PCB.My questions:Is this more likely caused by ADC sampling timing or switching noise coupling?Would increasing ADC sample time help in this case?On the PCB side, should I separate analog and power ground planes or just improve return current paths?

Dear STM expert:     Currently, Iam facing an issue:when using the stm32f030f6p6 chip, I cannot find this chip model when creating new projects in stm32cubeide and stm32cubeMX ,thus it making it impossible to new projects,what this?hope a reply..thanks.

New question split from this post. OK THANK  YOU @mƎALLEm , CAN U SHARE THE RMII CONFIGURATION FOR STM32H745BIT6?  

I've developed on an STM32U5A9J-DK using ThreadX, which, via USBX, creates a loopback audio interface between the PC and the device in the way: PC->speaker on device->microphone on device->PC.The devices are correctly seen and are working, as I'm able to enumerate them on the host and the device correctly receives audio frame,s and I'm able to process them into the device.Now, the issue is that I'm unable to send the audio packets back to the host.My implementation is pretty simple: I'm using the USBD_AUDIO_PlaybackStreamFrameDone function to read the audio frames and send them back to the microphone interface withVOID USBD_AUDIO_PlaybackStreamFrameDone(UX_DEVICE_CLASS_AUDIO_STREAM *audio_play_stream, ULONG length) { UCHAR *read_buffer; ULONG read_length; UCHAR *write_buffer; ULONG write_length; AUDIO_FRAME_MSG frame_msg; AUDIO_FRAME_BUFFER *frame_buf; /* -------------------------------------------------------------------------- */ /* STEP 1: Get A

Hi everyone,I have a screen project displaying a camera image using an STM32N6. I've validated and run several peripherals like DCMIPP and DMA2D. I'm currently displaying a 720x576 resolution image from DCMIPP on the screen via layer 2 using bitmap addressing.My question is: Since I'm using internal RAM, Touchgfx uses one layer, and one layer is used for the camera. Because I'm not processing any bitmaps and need space, I've significantly reduced the size of the cmd_list area. After adding all this, I have about 300kB of free RAM left.Now, what I need is to be able to see this camera image in full size on my 1024x600 px screen. However, I want to know if this enlargement is possible and if it requires a cmd_list, i.e., vector graphics.Will I use vector graphics for this? Will GPU2D use the RAM allocated for layer 2 for this operation, or will it require an additional amount of RAM equal to the screen size? Best Regards,Onur 

We are currently using LPTIM1 to measure the time period. As this operation needs to be performed frequently, we are using the following APIs:   HAL_LPTIM_TimeOut_Stop_IT(&hlptim1) HAL_LPTIM_TimeOut_Start_IT(&hlptim1, 0xXXXX, 0xXXXX)   During this process, the LPTIM_Disable() function temporarily disables all interrupts using PRIMASK while waiting for the LPTIM_FLAG_ARROK and LPTIM_FLAG_CMPOK flags.   This global interrupt masking is causing data loss on LPUART1, which is operating at 115200 baud. As a result, we are encountering ORE (Overrun Error) due to missed UART interrupts.   Given this behaviour, we would like your guidance on the following:   Is it safe to modify the LPTIM_Disable() implementation by removing or commenting out the PRIMASK-based global interrupt disable? Alternatively, is there a recommended approach to avoid this blocking behaviour while still ensuring correct LPTIM operation?   We are concerned about maintaining real-t

Hello,I'm trying to write to configuration register of P3T1750 sensor, I can perform this with I2C protocol but it not successfully with I3C, the sensor still ACK the write command but it NACK the read command to configuration register. With the temperature register i can read value with I3C.I just want to confirm that this is I3C/I2C sensor but the configureation register only r/w by I2C controller, right?

I am trying to build a custom Yocto Scarthgap image for a custom STM32MP153CAA3 board.I have followed the guide at https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machine but have several issues.I have created a configuration in CubeMX 6.15.0 and exported the DTB into my project.When I try and build I get an error in u-boot ERROR (phandle_references): /soc/rcc@50000000: Reference to non-existent node or label "clk_hse"(along with references to other clock nodes)I do a `devtool  modify u-boot-stm32mp`  to get at the source code and follow through the DTB The includes from the u-boot DTB file from CubeMX are:#include "stm32mp153.dtsi" #include "stm32mp15xa.dtsi" #include "stm32mp15xxaa-pinctrl.dtsi" #include "stm32mp15-m4-srm.dtsi" #include "stm32mp15-scmi.dtsi"stm32mp153.dtsi includes stm32mp151.dtsi which references the clocks, which is great.However the last include, stm32mp15-scmi.dtsi then goes and deletes them all!/delete-node/ &clk_h

Hello,coming from OpenSTLinux 4.2 (mickledore) we are in the process of migrating to OpenSTLinux 6.2 (scarthgap).The process of how multiple partitions (bootfs, vendorfs, userfs) are "split out" of the rootfs appears to have changed considerably.After switching all relevant meta layers to the commit/version used in OpenSTLinux 6.2, we effectively get bitbake QA errors for every image recipe (even the ones not being built). The errors appear related to the new bbclass "stsplitpartitions".The release notes of OpenSTLinux 6.2 mention the change as "Add image class to split rootfs image on several partitions: ST SPLIT PARTITIONS", but fail to provide any guideline on how to migrate existing projects to the new partitioning scheme.For testing, I removed all our proprietary layers and only kept the ST layers and standard Bitbake/OpenEmbedded layers.But the errors persist even for this minimal setup when building the standard ST image recipe st-image-core.How does st-split-part

Hello,I have recently installed and launched stm32cubeai studio latest version and it appears to be hung at launch screen with progress bar in motion.I have tried to close this from task window and tried uninstalling and installing it but still same issue.restarted the pc as well. What could be the issue. I have still 10 gb of hard disc space left. Br, 

Hello, I used MX2 for the last two weeks and it is a great improvement over MX. I build many small projects with it and I am constantly running into a problem related to timer configuration. I enter the values for the Prescaler and the Counter period as Integers and unfortunately when I close the project and reopen MX2 converts the value to Hex (and indicates that it is a Hex value). I keep forgetting that MX2 does this and I enter a new value as an Int thinking that my selection was sticky. Could you make the Int/Hex selection sticky? It's a small issue but it will save developers some trouble. Thank you,Gil

It looks like I have the 32F469IDISCOVERY board that looks to be powered ok via USB connector CN13, however the board doesn't appear to have demo software preloaded. COM LED LD6 flashes red. I note on the ST website that there is the 32F469IDISCOVERY compiled demo binary, which I have downloaded. The Readme says: The QSPI external flash loader is not integrated with supported toolchains, it ís only supported withSTM32 ST-Link Utility V3.7 or later. But the ST website says that the ST-Link Utility is NRND and to use STM32CubeProg instead. I've tried the latest version of STM32CubeProg and it can't connect to the board via USB: Error: Establishing connection with device failed. What is the best way of programming the board with this file please? Kind regards, Al

CubeMX 6.17. When creating a new project for H533RETx or for the corresponding Nucleo-H533, SYSCLK is set at 32 MHz.Not sure whether or not it is intended, but it looks like a trap for a new user, since the MCU datasheet talks about 250 MHz.Instead, example projects for Nucleo-H533 (at least the couple that I've seen) quite reasonably run the MCU at 250 MHz, driven from the crystal present on the board.

Dear,When running the FSBL that includes HAL XSPI initialization logic on the Nucleo-N657X0-Q board (MB1940-N657X0Q-C02), the flash erase with the STM32CubeProgrammmer v2.22 sometimes fails. However, if I leave out the XSPI initialization logic for accessing the NOR flash, flash erase always succeeds. BOOT pin 1 is set to DEV and I am loading the FSBL firmware directly into RAM.Do you have any idea why XSPI Init causes the flash erase to fail ?BR,EdwinD 

I have created a project with a scroll wheel of 10 items, each item is displaying a single digit 0-9. Imagine an odometer for instance.  I am incrementing a variable(num) every second and usingscrollWheel.animateToItem(num, 20);to scroll through the list of items, it is working as expected until it gets to 9. Instead of it the scroll wheel continuing to rotate the same direction to 0 it reverses the direction of rotation and scroll past all other digits to get back to zero.  I have verified I have the scroll wheel set as "Circular" and it does indeed display the scroll wheel correctly as if it was circular.  Can I somehow change this behavior?

Hello, we have a working design that is in production, but obviously cannot keep building because of the EOL variable capacitors. Our application is reader only, no card emulation. Since we don't need CE, do the variable capacitors need to be populated? Or can they be replaced with a fixed value capacitor? If the latter is correct, then what value capacitor to use? We want to minimize changes to the design since it is working well. In the future we will change to the ST25R300 bur right now we have to stick with the current design. Thanks,Derek

1. Where can I find pin function list for SPC582B60E1CD00X MCU. Package: eTQFP64  2. Suggestion on tool used to configure pins according to application and generate code.

  I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could get a green ACK indicator. The results were: Only cell 1 showed a voltage, but it was incorrect (5.8 V). When I try to write or read any register, I receive an ACK, but the register value does not remain as written. I also tried to connect VBAT (P2-15) to C14 (by soldering R22) and GND (P2-9 or 23) to C0, but in this configuration the device does not start and the D13 LED does not blink. I tried several times, resetting all the power supplies in different sequences, but I still could not communicate with the device. After returning to the initial setup, powering the L9963 with 12 V, I was again unable to configure the ID or take any measurements.    

can someone help me with communication of l9961 chip to get voltages of 4s cells n current n charge accumulated by using esp32 or aurdino i dont have this chip n i am not a coder i tried my best but can get any data from the chip just i2c add 0x49 n this register 0x00 gives  0x41 n nothing please hep
