I use STM32_Programmer_CLI.exe (from STM32CubeMX version 2.11.0) to flash an STM32 with internal and external flash. In some cases the tool prints an error in red in the terminal and exits with errorlevel is set to 0.If I want to use success or failure as a condition in my script I run into problems.I have the following simplified script (test.cmd):@echo off set "STfilepath=C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe" "%STfilepath%" -c port=swd -w "elf_file.elf" 0x90000000 -el "stldr_file.stldr" echo ERRORLEVEL=%ERRORLEVEL%If my debugger is not plugged or the target is not connected I get ERRORLEVEL=1.If my debugger and target are both connected, but either the elf file or the stldr file are not found I get an errormessage printed in red in the terminal, but the errorlevel is set to 0.No programmer connected:./test.cmd ------------------------------------------------------------------- STM32CubeProgrammer v2.11.0 -------------------

I ran into a small footnote in AN3155 stating "System reset is called only for some STM32 BL (STM32F0/F2/F4/F7) and some STM32L4 (STM32L412xx/422xx, STM32L43xxx/44xxx, STM32L45xxx/46xxx) products."Now I run into the problem that after flashing the firmware over UART, I need to be able to boot the new firmware since the device does not reset by itself. Over UART there is no reset command. I tried the "go" command to jump to 0x08000000 but that does not work either. STM32CubeProgrammer_CLI.exe reports that the "go" command is not supported on my device. Now I'm stuck. How do I run the newly uploaded image without having to powercycle or reset? I'm unable to do that in this product application. I do not want to use SBSFU.

This is a question related to an old post I wrote: https://community.st.com/s/feed/0D53W000024ZvOoSAKIn which I said that I will make some hardware modications in order to achieve the technical suggestions and manufacturer instructions. First it was thought that two missing capacitors were causing miss function on internal regulator. So I added them in a new printed circuit prototype. I have made these changes, but problems still being the same:Interruptions never happens after HAL_Init()So, thread get stucked at the same point: clock is never get configured, it tourns an error. I'm using HSI clock, so external clock couldn't be guilty. As a reminder I have to say that the same firmware works fine on NUCLEO board.I don't know if the problem is on SEGGER debugger configuration. I really need to be able to run some kind of firmware. I'm spending a lot of time with this trouble. Why is the interruption unable to be triggered when: TIM6 interruption is enabled and I can see how this is don

Hi, I am using cubeMx generate the STM32F302VE project, which for receiving the usart1 date by DMA circual mode.My config as below:enable DMA, but disable DMA interrupt;enable USART1, and enable UART_IT_IDLE;Now, the project can enter the "USART1_IRQHandler()", but can't run to "__HAL_UART_CLEAR_FLAG(huart, UART_CLEAR_IDLEF);", because "huart->ReceptionType != HAL_UART_RECEPTION_TOIDLE". Details can refer the attachment and the following picture.

stm32h7xx_ll_utils.c throws a warning "no LL_RCC_CalcPLLClockFreq" function at line 930. The function exists in stm32h7xx_ll_rcc.c but has a conditional compile USE_FULL_LL_Driver.Calls to conditional compiles should be under the same conditional conditions.Cheers, Hal

Enabling any interrupt at the initialization triggers the WWDG_IRQHandler when watchdog timer doesn't even configured in the code whereas excluding bootloader fw doesn't seem to cause any issues, code runs fine. In the bootloader fw, I haven't configured any interrupts except the cubemx generated system interrupts such as NMI, Hardfault, svc, Pendsv, systick and RCC_CRS. I've ensured to define handler for all interrupt request in the app fw. code is developed for stm32g0b1ret6 mcuHere is my jump to app code look alike:SYS_ERR_t SYS_JumpToApplication() { // This is the offset to the application execution region // Ideally this puts the flow of control of the application to right // After the Vector table const uint32_t NUMBER_OF_INTERRUPTS = 30; uint32_t *executeAddress ; executeAddress = (uint32_t*) 0x08020000; // Creates a pointer pointing to start of Application address space void (*ApplicationFunction)(void); /// Points function pointer to its reset handler ApplicationFu

Hello,I worked until now with FreeRTOS. And in FreeRTOS there are Trace Hook Macros.Is there an equivalent on Azure RTOS ThreadX?Trace hook macros on FreeRTOS are a very powerful feature that permit you to collect data on how your embedded application is behaving.Key points of interest within the FreeRTOS source code contain empty macros that an application can re-define for the purpose of providing application specific trace facilities. The application need only implement those macros of particular interest - with unused macros remaining empty and therefore not impacting the application timingSpecifically I am looking for:traceTASK_SWITCHED_IN()Called after a task has been selected to run. At this point pxCurrentTCB contains the handle of the task about to enter the Running state.traceTASK_SWITCHED_OUT()Called before a new task is selected to run. At this point pxCurrentTCB contains the handle of the task about to leave the Running state.I looked at the Azure RTOS documentation but co

The code below links Timer1 in master mode to Timer3 in slave mode producing a 4 second toggle on PB8 and it works correctly.My question is I'm not able to follow the flow of the signal in the Timer chart below the code.If someone would show me the signal flow I would appreciate it. I have shown how I think the signal flows. Is this correct?void LinkTimer1And3(){   // GPIOB clock enable   RCC->IOPENR = 2;   // Set PB8 alternate function   GPIOB->MODER &= ~(3 << 16);   GPIOB->MODER |= (2 << 16);   // Alternate function to TIM3 CH1   GPIOB->AFR[1] &= ~0x0f;   GPIOB->AFR[1] |= 3;   // Enable TIM1 and TIM3 clocks   RCC->APBENR2 |= (1 << 11);   RCC->APBENR1 |= (1 << 1);   // Master Mode Selection - Select Update Event as Trigger output (TRG0)   TI

Hello,I followed this guide:https://community.st.com/s/article/how-does-the-threadx-semaphore-workAnd everything works.But when I try to add a modification, a HAL_UART_Transmit - HAL_UART_Transmit(&huart2, (uint8_t *)&message, 1, 10); - in one thread I always get the error 'huart2' undeclared. Well huart2 is declared in my main.c but of course not in the app_thread.c. And there are my threads. So my question is how can I solve this error? With FreeRTOS I just created threads and all the code in my main.c so there was no issue to use HAL_UART. But I am not sure how to solve it on ThreadX?

Hello,in the Semaphore example(https://community.st.com/s/article/how-does-the-threadx-semaphore-work) there is this step:Open Core\Src \main.c – you can copy and paste the code below, but please notice the" USER CODE BEGIN", to properly place the code snippet:/* Private user code ---------------------------------------------------------*/   /* USER CODE BEGIN 0 */   #define USE_UART_PRINT   void __io_putchar(char ch) {   #ifdef USE_UART_PRINT   // Code to write character 'ch' on the UART   HAL_UART_Transmit(&huart3, (uint8_t *)&ch, 1, 10);   #else   ITM_SendChar(ch);   #endif   }   /* USER CODE END 0 */The question I have is why is this step and piece of code needed? I understand the previous steps and the code that I need to add in the \app_threadx.c file. But this part I am not sure and it is not explained in the guide.Can anyone please tell why this part is needed? Thank you

I'm trying to follow the reference manual to use USART over USB via VCP (bare metal), but Realterm isn't able to read *any* data. According to the user manual, USART/VCP over USB should be supported, mentioning it's on the PC4,PC5 pins. Here's the code I'm using:#include <stdio.h> #include "stm32f303xc.h"   /* USART1 is an alternative function of GPIOC */ #define GPIOCEN (1U << 19) #define USART1EN (1U << 14)   /* USART1 -> CR1 Control Register */ #define CR1_TE (1U << 3) #define CR1_UE (1U << 0)   #define SYS_FREQ 8000000 #define APB2_CLK SYS_FREQ   #define USART_BAUDRATE 9600   static void usart_set_baudrate(USART_TypeDef *USARTx, uint32_t PeriphClk, uint32_t BaudRate); static uint16_t compute_usart_bd(uint32_t PeriphClk, uint32_t BaudRate);   void usart1_tx_init(void); void usart1_write(int ch);   int main(void) { usart1_tx_init();   while(1) { usart1_write('H'); usart1_write('i'); } }   void usart1_

Hello everybody,My name is Rego, as a hobby I work on displays, image processing, etc...I'm not very familiar with ST, but I'm really enjoying these MCU. I've already implemented RTC using VBAT and it works very well. Now I want SRAM backup,On battery it loses data I can't understand the reason for the problem, can anyone help me?thanks

helloi am working on a custom bootloader or STM32F405.the Flash process is done correctly by the Bootloader, i checked the content of the flash.the problem happens when the bootloader jumps to the application firmware which is located at adress 0x0800C000, the program goes to the Hard_fault handler function: this is what i am using to jump from the bootloader : thanks.

So firstly, I'll explain what I'm trying to achieve. My company is planning to utilize an STM32H7B0 because it's the chip that we were able to find stock of. For testing, I'm using a STM32H7A3 because it was available as a Nucleo board. The primary requirement we have is that updates to the device must have as little downtime as possible. Functionally this means that an update should be downloaded into a second image slot during normal operation, and then switched with as little downtime as possible. This would be simple using the H7B3 or H7A3, but we cannot find available parts.My current approach is to use MCUBoot to load the image into RAM from a slot contained in a QSPI NOR flash. This also enables us to encrypt the image in the QSPI for IP protection. This is also the primary reason I'm not pursuing XIP. In theory this approach should work just fine, and I've already confirmed that the software runs just fine out of RAM instead of flash.The problem I'm facing is in setting up a sa

Hi all,is it possible to connect a SDCard to the stm32f723e-disco [1] board? The webpage [1] is talking about some microSD connector, but I do not really find one. So is this a mistake on the webpage?Additionally, I would like to ask, if it is possible to expose the SDIO pins (CLK, CMD, DATA[0:3]) through the GPIO pins such as the Arduino header for example. This would allow us to connect an SDCard through a external break out board [2]. If so, would it be possible receive an example code how to do so?Ideally would be some device tree configuration how to configure the PINCTRL, because I develope the application with Zephyr RTOS [3].Thanks in advise.RegardsAndi[1] https://www.st.com/en/evaluation-tools/32f723ediscovery.html[2] https://learn.adafruit.com/adafruit-microsd-spi-sdio[3] https://zephyrproject.org/intro-to-zephyr-rtos/

A year ago I heard from a friend that there was a problem with the STM32F103's hardware I2C. All the ones I found on the internet said there was no problem with the hardware I2C of the ST, but not the F103 series. So, I have two questions. First, I want to know if the hardware I2C of the F103 series still has problems now. Second, what is the problem with the hardware I2C of the F103 that was once circulated and how to deal with it.Translated with DeepL

breakpoint reached normal;from here this jumps to "show.."and then this breakpoint seems never reached, but when going step by stepline 1354 is reached and also the following "sprintf.." , but it gets curious:when "Radio.." text is selected , is drawn on TFT and program runs on,but when"PLAY..." is selected, it never prints and "hang up" in some loop around DMA-INT-busy-ready-DMA...endless. but no hard-fault coming, just busy looping.+ i did something...probably...because some days before all this working without any problem (since many weeks) and i changed nothing here. just i made some "improvement" in grouping the "chars" and "uint8" together, just for better clarity.and then tried to improve the ESP web radio program, (-> Radio-ESP active);just today i found the other "play" hanging up...i would be happy with any idea, whats wrong here now.just...this is the asm here:

On a stm32 mcu, using HAL_I2S_Receive_DMA the clock generation is started. At first, the application went into a hard fault and nothing is subsequently written in the data receive buffer.HardFault_Handler:08000942:  push  {r7}08000944:  add   r7, sp, #0 89     while (1)08000946:  b.n   0x8000946 <HardFault_Handler+4>I corrected some settings and now it is in BUSY mode which is fine. However, now the receive data buffer does not get filled. What is the reason that the receive data buffer doesn't get filled:uint16_t i2s_receive_buffer[100];HAL_I2S_Receive_DMA(&hi2s2, i2s_receive_buffer, sizeof(i2s_receive_buffer));

Hello. I use a SwipeContainer with 2 pages. I have a button with which I want to switch to another page. But the simulator and also the STM32F7508 crashes. Does anyone have an idea to solve this problem?

Hello,i am porting a project made initially on STM32H750, but because of the semiconductor shortage on the market, the only available part was a stm32H725IGK6, which i started working on.Regarding the usb connection, i have the following pins used:PA9 - connected via 10k resistor to 5VusbPA10 - connected to ID usb pinPA11 - connected to DN usbPA12 - connected to DP usbDoes this devices supports VCP over usb? Because i am trying to work with some usb cdc examples, but so far i am not able to make it visible on the computer.

Hello,i intend to use a STM32H725IGK6 device in my design.The system will be suplied from a single 3.3 voltage source.Apart from VDD,VBAT pins, i see this device has some VDDLDO pins, and 3 VCAP pins.How shall i power the vddldo pins? Can i tie them together with VDD supply ( 3.3V) ?As i understood the vddLDO pins is supling the internal core regulator.And what about the VCAP pins? All 3 vcap pins must be connecter together with capacitor to ground? Or every vcap pin separate tied to GND via capacitor?
