I am encountering a warning when trying to generate code for both existing and new projects in STM32CubeIDE 1.14.0.  This did not happen in 1.13.x. I get the following warning.  I have been generating the code and it appears to work, but I don't know if anything is incorrect.  To reproduce the warning, I create a new STM32 project for the STM32U5A9J-DK board, choose to initialize all peripherals to defaults, and save the project.  When it attempts to generate the code, I get the warning displayed. I also started encountering this with an existing project (migrated to version 1.14.0) for a NUCLEO-U5A5ZJ-Q board.

Hii all,First of all i am new to bluepill(stm32f103c8) and i want to use both the SPI1 & SPI2 for the same project .BUT i don't know how to use it i am using Arduino ide for code 

Hello @John E KVAM ,Table 14 in the datasheet shows power consumption in Autonomous as going as low as 4.5 mW, but is this only the AVDD power? or total device power? Because I do measure low power draw at those levels, but only on the AVDD pin (and those power levels vary with sample rate, per the datasheet). But the IOVDD continues to draw 22 mA at 3.3v in addition to a few mA for the VCSEL on AVDD. I'm pretty sure the device is really in Autonomous because calling vl53l5cx_get_ranging_mode() returns a '3' for Autonomous. But I'm unable to turn off that big power suck on the IOVDD pin. I was hoping this part could be a low-power motion detector, but if I'm stuck with ~100 mW or more then it's not very low power.One issue might be that I'm using threshold detection. Is that what keeps the core digital stuff drawing power? Can I run a low-power Autonomous mode if I don't set thresholds?Another possible issue is that calling vl53l5cx_get_power_mode() returns a comms

Hi,I am using STM32G4 in my project. I need delays in my project multiple places. I am using hardware timer interrupt for delay. I am using TIM1 configured with 50 usec delay. HAL_TIM_Base_Start_IT(&htim1); HAL_TIM_PWM_Start_IT(&htim2, TIM_CHANNEL_2); void HAL_TIM_PWM_PulseFinishedCallback(TIM_HandleTypeDef *htim) { if (htim->Instance == TIM2) { if( flag_50 usec==1){ //read adc; flag_50 usec=0; } if(flag_800usec==1){ //check switch high/low flag_800 usec=0 } } } void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if (htim->Instance == TIM1) { uint16_t varible=0; flag_50 usec=1; variable++; //take one variable to increment timer if(varible==16) flag_800usec==1; } }1.As mentioned I need different  delays in my project. For every pwm pulse rising edge after 50 usec I need to adc value and then after 800 usec I need to check one switch high/low. It should be repeated process. I am planning to use same timer for dela

Hello,I have problems with a Custum board with a STM32H735IGK6 controller. I can flash a firmware once, after that I have no connection to the microcontroller and the software does not want to start.Problem description:BOOT0 = VDD--> Microcontroller is recognized by STM32CubeProgrammer, STM32CubeIDE flashes firmware and then loses contact to the controller. The microcontroller does not start the user program (which was tested successfully on a STM32G431: LED flashing, otherwise no further commands).BOOT0 = GND--> Microcontroller not recognized neither by STM32CubeProgrammer nor by STM32CubeIDE. Exception: Previous Mass Erase with BOOT0 = VDD, disconnect from power supply, BOOT0 = GND, switch power supply on again)I have already applied some solutions from this forum:- Mass Erase with the STM32CubeProgrammer.- ST-Link ISOL replaced by ST-Link- When flashing the option "Shared Programmer" selected- Flash speed loweredFurthermore I have the log file of the STM32CubeIDE:[3.435] spawn

Hello, I'm using a STM32L552CCT6. For firmware update I want to use the dual flash bank functionality of the controller.When switching the flash banks with the option bit SWAP_BANK in register FLASH_OPTR what happens to the program counter? Is he also switched to the now second bank to continue the execution of the firmware?Best regards,Markus

Hi guys. Help solve this problem.I am working with STM32H745 and ThreadX. In my project, an external event generates an interrupt on EXTI10.The tx_event_flags_set() function is executed from the HAL_GPIO_EXTI_Callback() interrupt handler to start a process that must perform certain actions. According to ThreadX recommendations, custom interrupt handlers from which RTOS functions are called are assigned the smallest interrupts. But when I assign EXTI10 Preemption priority=15, the program is unstable. And when I set Preemption priority=0 everything works fine. What could be the problem?

Hello,I'm trying to read the OTP flash form my application but I get a hardfault.Is there a read protection or something like that? Here is a code snippet:#define FLASH_START_ADDRESS 0x08FFF000 int main(void) { HAL_Init(); uint32_t* flash_data = (uint32_t*)FLASH_START_ADDRESS; uint32_t data = *flash_data;

 ST Link not recognizing STM Cube Programmer? - From screenshot you can see NO ST Link detected in serial number drop down and has no target information. I can (and did) upgrade firmware, On doing so, it's throwing following error( ST-Link device lost when exiting upgrade mode). Still won't connect. Keep getting "UR connection mode is defined with the HWrst reset mode" log entry. 

What is the actual unit (dBV, dBSPL etc.) for the plot? dB is not relative to Volt or anything. 

Hello!I am working with the STM32H747i-Disco board, my aim is to create ethernet connectivity between the board and the PC, as a first step to send a ping from the PC to the STM32H747i-Disco and get a response. My cubeMX version is 6.2.1, the H7 firmware repository is version 1.9.0.first, i have made the nessecery HW modifications to the STM32H747i-Disco board in order to connect the proper ethernet pins to the MCU. (SB8 closed, SB21 open, R87 open, SB17 closed).i have defined a cubemx project according to the instructions in this link: https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working . with two exclusions:The ethernet is defined in RMII mode (since MII isnt possible on the STM32H747i-Disco). Clock source is HSI (and not HSE) - but still with 400 MHz for the M7 cortex (the ethernet is connected to the M7). I Also tried defining teh HSE option, it didnt change the outcome.i configured the PC ethernet connection to a static IP (192

Hi, I used this code to change the boot address in the STM32U575 project:FLASH_OBProgramInitTypeDef OB_Data;/* Unlock Flash Control register and Option Bytes */HAL_FLASH_Unlock();HAL_FLASH_OB_Unlock();OB_Data.OptionType = OPTIONBYTE_USER | OPTIONBYTE_BOOTADDR;OB_Data.USERType = OB_USER_TZEN | OB_USER_NBOOT0 | OB_USER_NSWBOOT0;OB_Data.USERConfig = OB_TZEN_DISABLE | OB_NBOOT0_RESET | OB_BOOT0_FROM_OB;OB_Data.BootAddrConfig = OB_BOOTADDR_NS1;OB_Data.BootAddr = addr;/* Program Option Bytes */HAL_FLASHEx_OBProgram(&OB_Data);/* Launch Option Bytes Loading */HAL_FLASH_OB_Launch();How to do the same in the STM32G0xx project? 

At the moment, I am using the default firmware on the ST25R3911B-DISCO and have been reading and writing to a ST25DV04K tag. I know that the ST25DV04K tag supports a size of a 256-byte buffer, but I am wondering if the ST25R3911B does as well. If it does, what would I need to change in the firmware?

HelloI am new with using STM MCU's (STM32G474RET6) and encounter very strange reset behavior.In my application reset of the MCU can be done in 3 different ways. 1. Hardware reset - by pressing on button.2. Software reset - by executing NVIC_SystemReset() function.3. By swapping from bank 2 to bank 1 in dual bank mode.Currently I have problem only at bank's 2 image (reset of image burned to bank 1 done good in all 3 mentioned ways).Also, the reset problem seems to be somehow depended on firmware (bank 2 image) compilations. Sometimes after compilation (with even minor changes in firmware) it is working fine.  The problem is that after performing reset (by example pressing on button) MCU seems to be stacked or doing something and not enters even a main (while 1) loop where I am toggling indication led for test. I must press again - second time on the reset button in order to release an MCU.'Debug As' function not working - it fails on execute MI command.Any idea what

Hi!I am using the stm32mp157C-DK2 board to communicate via FDCAN and my idea is to use it as normal mode to send and receive CAN messages. For this I have created a program in stm32cubeide and I enable FDCAN1 with the following parameters (125Kb/s): hfdcan1.Instance = FDCAN1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan1.Init.Mode = FDCAN_MODE_NORMAL; hfdcan1.Init.AutoRetransmission = ENABLE; hfdcan1.Init.TransmitPause = DISABLE; hfdcan1.Init.ProtocolException = DISABLE; hfdcan1.Init.NominalPrescaler = 8; hfdcan1.Init.NominalSyncJumpWidth = 3; hfdcan1.Init.NominalTimeSeg1 = 20; hfdcan1.Init.NominalTimeSeg2 = 3; hfdcan1.Init.DataPrescaler = 16; hfdcan1.Init.DataSyncJumpWidth = 6; hfdcan1.Init.DataTimeSeg1 = 5; hfdcan1.Init.DataTimeSeg2 = 6; hfdcan1.Init.MessageRAMOffset = 0; hfdcan1.Init.StdFiltersNbr = 1; hfdcan1.Init.ExtFiltersNbr = 0; hfdcan1.Init.RxFifo0ElmtsNbr = 1; hfdcan1.Init

Hello,currently, I'm in the production phase of my product which is based on stm32mp153. Unfortunately, I have a huge problem with setting the password for root.First I commented debug-tweks in local.conf.I added  INHERIT += "extrausers" EXTRA_USERS_PARAMS = " \ usermod -p '$5$otifn3fxcID0nu0c$QUDR.mLMbgEgl26XPEX6Rm6ASUB0ab8UFtQHdoEOBt4' root; \ " hashed or not based password but I can't login into root using ssh.Then I discovered that I could still log in through the serial console without providing anything. I found and commented 'serial-getty@.service'line ExecStart=-/sbin/agetty -8 --autologin root -L --keep-baud %I @BAUDRATE@ $TERM to ExecStart=-/sbin/agetty -8 -L --keep-baud %I @BAUDRATE@ $TERM  Additionally, I updated sshd_config file line PermitRootLogin prohibit-password toPermitRootLogin yes  And finally, the result is that I can't log in via serial and ssh.I read some issues from the linkhttps://community.st.com/t5

I'm building up an app on the STM32L4R9-Discovery board that needs a lot of IO: UARTs, USARTs, I2C, SPI,RTC, FatFS on the SD Card and others. I'm pretty new to the STMCubeIDE and C/C++ world so I've build up several test apps that start for the Discovery board based on examples from the HAL library. Now I'm trying to combine my SD card example with my RTC example. They work find separately but when I try to put them together I get a HAL_Timeout error in the RTC_EnterInitMode method in the STM32L4xx_hal_rtc.c file. This happens with the STMCubeIDE and in VisualGDB.HAL_StatusTypeDef RTC_EnterInitMode(RTC_HandleTypeDef *hrtc) { uint32_t tickstart; HAL_StatusTypeDef status = HAL_OK;   /* Check if the Initialization mode is set */ #if defined(STM32L412xx) || defined(STM32L422xx) || defined (STM32L4P5xx) || defined (STM32L4Q5xx) if ((hrtc->Instance->ICSR & RTC_ICSR_INITF) == 0U) { /* Set the Initialization mode */ SET_BIT(hrtc->Instance->ICSR, RTC_ICSR_INIT);

hi Im developing my board using stm32f429ZITx by keeping stm32f429 disc 1 as a reference Im using the entire GPIOG port for parallelly reading the 16-bit data as some of the GPIOG pins are used by DRAM ( i.e U6   IS42S16400J a dram ) is it possible to read?Or is it necessary to keep DRAM?   

Hello forum members, I am currently working on a custom PCB based on the STM32U575ZIT6 microcontroller. I've encountered an issue when configuring PLL1 as the clock source – the code generates a hard fault. However, when selecting HSI or HSE as the source, everything works fine. The challenge is that I am unable to achieve the desired 160MHz clock speed without using the PLL. I've observed that in the RCC (Reset and Clock Control) section, when I choose HSE or HSI, the regulator_voltage_scale is set to level 4. Interestingly, manually changing it to levels 3, 2, or 1 results in a hard fault. I would appreciate any insights or suggestions regarding this issue. Has anyone encountered a similar problem with PLL1 configuration on the STM32U575ZIT6, or does anyone have recommendations on resolving hard faults related to clock configuration? Thank you in advance for your assistance. Best regards,

Hello!Im having some problems with STM32F429ZIT about the interrupt handler. My microcontroller is connected on a LCD display by LTCD bus pheripheral and also has a interrupt input pin (PG2 - EXTI2 on falling edge detection border) connected on a external driver. All the hardware connections are ok.The problem is that my EXTI callback is being triggered even if i let PG2 always in low! At this moment my callback funcion has just only this code to test: void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){if( GPIO_Pin == GPIO_PIN_2) HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);} Note: the LCD display is being controlled by a GUI library from STemWin. I have noted that when i disable the library (remove the init function from my main code), the interrupt handler of EXTI works as expected. But if i enable the LCD, the interrupt handler get triggered randomly.Can someone give me some idea about wich trouble is and a solution?Al the others GPIO Pins 2 are disabled (none of them are also u

I have an STM32WB55 Nucleo Pack and i thought i'd try out the BLE heartbeat monitor example on the MB1355C board, so i opened up the STM32CubeProgrammer, put the power selector to USB STL and could connect ok.I Selected the hex file for the heartbeat monitor example and used the Automatic option to try to write it to the board. It said it finished writing to board N:1, connect board N:2 and hung. So i disconnected the board and plugged it back in and i noticed not much was happening, and i couldn't see the bluetooth device using my phone, so i tried to connect it back to the STM32CubeProgrammer and i noticed it would no longer connect.If i open the cube programmer, and select "Firmware Upgrade" no device appears. However, if i click the button that says "Open in Update Mode" the board resets, device information appears and i can upgrade the firmware. The board still mounts like a drive and i can still drag files into the drive which magically disappear after the board is reset.Can anyo

Hello,I want to make a design with the ADC1283 where DVCC is powered by a 5V buck converter, and AVCC is powered off a 4.5V voltage regulator (that's powered off the buck converter). Is this possible?I can't tell whether DVCC and AVCC are allowed to be significantly different from the datasheet.Not sure if this is the right category in the forum or not; couldn't find one that fit.
