Hi!I recently tried to put my Nucleo G071RB board back in use.Sadly it refused to work.I´m using Cube IDE, Windows 10 (64).After some research I found out, that Cube IDE is using ST-Link Server software to connect to the board, of which I installed the recent version.I could not find the associated process in my task manager.Even starting it manually could not do the trick.Console pops up and disappear again, no task!So I suspect ST-Link Server software.Board is updated to the latest firmware, using Cube Programmer and I also re-installed Cube IDE.Any suggestion?

I'm considering using a STM32L4P in a medical device design. What is this part's expected longevity in the market. Will I still be able to buy it in 5 or 10 years?Do any ST processors have a guaranteed product lifetime?

When my STM32G0B1KET receives an Discover SVIDs message, it responds GOODCRC, then the core library function PE_StateMachine_VDM() calls the reset handler. After reset the system hardfaults. System responds to discover identity properly. The USBPD_VDM_DiscoverSVIDs callback is properly initialized and not reached. A little stuck on this working with just the disassembly. Any suggestions for a fix would be appreciated.

Been looking closely at RM figures 342 AND 343.....I cannot see the value of the ARPE bit....when 1 it looks like the shadow register updates on UEV / or Interrupt and when 0 what?? 342 disregards showing the shadow register and on top of this who cares that it loads early when ARPE = 0.....Can someone please explain the value of this bit?

UNEXPECTED ID code?, the discovery board is original.the onboard stlink is updated to latest version.If i google this Error, i get people trying to flash ST clone mcus, but mine is original. This is my openocd.cfg file:source [find interface/stlink.cfg] transport select hla_swd set WORKAREASIZE 0x2000 source [find target/stm32f1x.cfg]   #reset_config srst_only srst_push_pull srst_nogate #connect_assert_srst   adapter srst delay 100 adapter srst pulse_width 100 bindto 0.0.0.0   init targets reset halt #program bootloader.bin verify program /stm32f0-discovery_ledblink/build/stm32f0-discovery_ledblink.bin 0x08000000 verify reset exit reset shutdown

Hello everyone,I have an application that eventually record some audios and is working fine with a pair of MP34DT01. It works over SAI with a clock of 1.024MHz and a decimation factor of 64 (for the PDM2PCM), leading to an audio frequency of 16kHz.The problem that I have now, is that I'm migrating the MEMS to MP34DT05-A. It seems to actually be working fine so far, but in its datasheets it states a minimum clock frequency of 1.280MHz. Therefore, ideally I should change the frequency of the SAI interface. I've done it and I've also changed the decimation factor to 80, as explained in AN5027 and UM2372. However, with these new configs, I obtained just noise (like a strong beep). I've checked the clock with the osciloscope and it is indeed 1.280MHz.Is there any other configuration (maybe related to the DMA?) that I'm missing here in order to be able to increase the SAI clock from 1.024MHz to 1.280MHz?Is it even necessary to do this frequency change? considering that although the datasheet

I'm using a STM32G070 MCU which I flash via i2c when the boot0 pin is set to high. This works fine until I connect a ST-link to the MCU, program it and then disconnect the ST-link again. After that the i2c flash will fail, I have checked the boot0 and reset pin and these are set correctly, but when checking the i2c communication it seems like there is no reply from the boot loader address 0x51. When I power cycle the MCU the i2c flash works fine again. I have checked the boot select bit in the user option byte and it looks ok. Anyone know if this is expected behavior after the ST link has been used or if it might be something I have missed?

I have a custom board with an STM32H7A3ZIT6Q. It has the MT25TL256 NOR flash connected to the pins of OCTOSPI1.I'm trying to write a flashloader/driver.In our application we do not need to execute code from this flash. We only need it for data. But if there is a way to get execution working that would be nice too.I'm following the tutorial from ST:ST tutorial:https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/external_QSPI_loader.htmlhttps://www.youtube.com/watch?v=YFIvJVsvIsE&list=PLnMKNibPkDnHIrq5BICcFhLsmJFI_ytvE&index=1Template project: https://drive.google.com/drive/folders/1KiaqXgiubk81EvevofK-y3LxrCl9NHfiSTM git repo https://github.com/STMicroelectronics/stm32-external-loader/tree/contribApplication note: https://www.st.com/content/ccc/resource/technical/document/application_note/group0/91/dd/af/52/e1/d3/48/8e/DM00407776/files/DM00407776.pdf/jcr:content/translations/en.DM00407776.pdfMCU Datasheet: https://www.st.com/resource/en/datasheet/st

I have a nucleo-U575ZI-Q and can run the examples for the ADCs just fine. However when I try and make my own project using STM32CubeMX the code hangs at the ADC calibration. I've gone over the settings a dozen times and compared them against the example and cannot find anything different. Any insight would be helpful. Thanks

I am trying to use LWIP on the STM32H723 Nucleo board to send and receive UDP packets. I have generated code using CubeMX version 6.70 and configured it to use LWIP with FreeRTOS. I have referred to the H7 series LWIP related problems and H723 address setting problems in this community. But when I run the project, it triggers the MemMange_Handler(void) and no longer proceeds. I believe the issue may be with the MPU configuration. If I don't set up MPU, the project runs, but I can't send or receive UDP packets. When I check packets using WireShark, I can only see ARP protocol when sending UDP packets. I would appreciate it if you could tell me the solution.

Hello, I have an application where we are using a couple of the ST25R3916B in a design but with a different processor. I've looked through the forum posts and gleaned some information here and there, but is there a guide on how to port this library to a different processor? It is the MSP430F5xx series. Or I don't suppose you have any example code that is already ported for this processor?We will be reading either the ISO15693 or ISO 14443 tags; that hasn't been decided yet.I'm using ST25NFC_Embedded_Lib_ST25R3916_1.4. I will be using the basic polling example.Ideally the porting guide would include:How to set up the directory tree so that everything is foundWhich files I will need to port to my own hardwareHow to test that we are communicating with the ST253916 successfully.Which middleware I need to includeAny "gotchas" or information that is important to know when portingThank you,Derek

Hello,I need to if it´s possible to perform an OOK modulation with the STM32WL55JC (433 MHz or 868 MHz). If so, how can I do it, and does somebody has an example for this?Thanks!

Hi,I'm wondering if it's possible to freeze the IWDG in stop mode for STM32F429. I couldn't find this option in the STM32CubeProgrammer. Not sure if this is feasible.Thanks,

Hi,I am looking to use the STM32U575CIT6Q in a USB project. The documentation everywhere mentions VDDUSB but that pin does not appear to be present on the LQFP48 package. Is it just tied to VDD internally? The data sheet appears to show that OTG FS is available on all of the different packages, so I'm not sure how the transceivers are powered.If the VDDUSB is internally tied to VDD then does this imply that VDD >= 3V?Thanks,TG

From the datasheet from the slave device: "First the host must write a command to the slave device. Then it must follow that command with a repeated start condition to denote a read from that device's address. The slave then returns two bytes of data.Note that there is not a stop condition before the repeated start condition, and that a "Not Acknowledge" signifies the end of the read transfer."The data format:S - Device Addr - Wr - A Cmd Code - A - S - Device Addr - Rd - A - Data Byte Low - A - Data High - !A - PThe Slave's responses are underlined.Any ideas? Thanks,Richard

Hi, i've been building self balancing robot, so i needed quite lot of periphelias to be working together, they are: I2C, EXTI's, two Timers in encoder mode, Timer in PWM generation mode and GPIO outputs.I'm using STM32CubeIDE 1.9.0., and STM32L432KC nucleo boardI've been enabling those peripherals one by one in cubeMX, and every time when i generated code i've checked if it works. (It all went fine, MPU6050, EEPROM, and LCD connected to I2C bus worked well, so i assume my hardware setup is good) Unfortunately, after enabling PA6 and/or PA5 as GPIO output, my I2C1_SDA and I2C1_SCL lines are immediately pulled down after powering up the device.That's weird behaviour because I2C1 has nothing in common with pins PA6 and PA5.Maybe i missed something in documentation or in chip errata.I posted the code (whole project) on GitHub because it's easy to see changes in the code between commits, it helped me a lot in finding this bug source (i suppose lol). I apologize if the names of the commits a

I have an STM32F403ZH Nucleo board and it's connected to three separate CAN channels. I would like to be able to receive identical messages on any channel (same identifier, baud rate, etc) and have the microcontroller be able to determine which one it came from so it can handle it differently. This would allow my three identical devices to not have to be reprogrammed to send messages with different identifiers.I've been looking through the reference manual and I don't think it's possible. The 3 different CAN controllers all send the same interrupt to the main controller. No trace of which CAN controller sent the interrupt or received the message is stored when the message is sent to the FIFO, or in the mailbox when the main controller receives the message from the FIFO. I could differentiate between two channels by having them output into different FIFOs, but not three. If anybody knows a way then I'd be happy to hear it. Thank you.

Hello, I want to flash a FW to my STSPIN32G4 custom boards that tests each phase FET individually by switching through the different high- and lowside FETs one per one. Is there an easy way to do this? Any help is appreciated.PS:All I found is a function to turn on all lowsidefets:  For the highside switches I know its more complicated because the bootstrap caps first need to be charged. I also found this init function:All I need is a code snippet to change the output state of those 6 pins from low to high and vice versa. Thanks! :)

Welcome, why for STM32MP157FAA1 at "STM32MP1 Series DDR memory routing guidelines examples" there is no terminating resistors?

Hi,I'm having a STM32G474 with Bootloader block (0x0800 0000 - 0x0800 4FFF) and Application block (0x0800 5000 - 0x0807 FFFF).I need to update Bootloader from Application, by copying a new bootloader located on higher memory. Is it possible ?I'm using the same code of the bootloader to erase the pages 0 to 4 but no success. I can't even write on the bootloader block.So is it possible to erase the bootloader from the running application ?Thanks
