STM32CubeProgrammer (MCUs)

Hi,I am using LED blink firmware generated using CUBE-MX by Disabling all the modes and Clearing the pinouts.I flashed one firmware in the bank-1 (0x08000000) and second firmware(with few changes the way the led blinks) flashed into the bank-2 (0x08018000) using the stm32 programmer. First I writing the firmware-2 into bank-2 like this. Next I am flashing the firmware-1 in the bank-1 and running .I kept the bank switch logic in firmware-1.My main() fun will look like this:int main(void) { /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init();   /* Configure the system clock */ SystemClock_Config();   /* Initialize all configured peripherals */ MX_GPIO_Init();   __HAL_RCC_SYSCFG_CLK_ENABLE();   int i = 9;   while (i > 0) { // printf("LED BLINK\n"); /* USER CODE END WHILE */ HAL_GPIO_WritePin(GPIOB, greenLed_Pin, GPIO_PIN_RESET); HAL_Delay(1000); HAL_GPIO_WritePin(GPIOB, greenLed_Pin, GPIO_PIN_SET); H

I am "Learning" assembly, So I have tried to program my stm32f103 in assembly (a simple program to blink a led). The problem is that the program runs when uploaded using st-flash utility. But, If I press reset button, the program stops working.Here are few things that I debugged in STM32CubeProgrammer.The program seems runs if do a reset from the programmer but not on board.I get a unable to run error If I try to run the CPU from CubePrg after manual button reset.Moreover the Program Counter register seems to jump to 0xFFFFFFFE in the above case (Not always). I am using Ubuntu and Nucleo-64 board.PS. I didnt use any startup_*.s file. Instead placed the 2 vector address by using word and main program at 0x08000200 using .org directiveEDIT:The program counter now always goes to 0.Code:.equ RCC_BASE, 0x40021000 .equ APB2ENB, RCC_BASE + 0x18 .equ GPIOA_BASE, 0x40010800 .equ GPIOA_CONF_L, GPIOA_BASE + 0x0 .equ GPIOA_BSSR, GPIOA_BASE + 0x10 .equ GPIOA_ODR, GPIOA_BASE + 0xC   .syntax uni

Hello ~My STM32H743 MCU can not get into USB DFU mode, which has initial bootloader version V13.2I follow the instruction, boot0 pin to high, plug usb, watching my device list, but there is no STM FS DFU device.I designed new board with stm32h743xi, 16Mhz, 10pf, 0 ohm, 32.768KHz, 6pf, There are BASE BOARD, and CPU Board, and did adjust impedance pairing USB_DM, USB_DP , all power managed by base board. The base board also fit to commercial other MCU board(stm32h743xi, bootloader version V9.0)Other Commercial CPU Board works well, I can see STM FD DFU device in the list​My question isWhat cause this issue cannot get into USB DFU mode?Bootloader version?, 13.2 version cannot get into USB DFU mode?or HSE?, LSE?or in the bootloader selection mechanism, my stm32h7 could select another boot mode like FD-CAN or I2Cx ?, or SPI detected?(CS PIN?)should put all CS Pin to HIGH?​for more information.i can downlad the hex file to stm32h743 thru the st-li

Good morningI am trying to create and use SPI EXTERNAL LOADER using STM32F410 CBT3. I created EXTERNAL LOADER using S25FL032P_STM32G071B_NUCLEO sent from STM. Data is read from STM32CUBEPROGRAMMER, but data mismatch found at address 0x90000000 occurs when the file is downloaded. Please check which part needs to be corrected.

I created an external loader, I tried it with STM32CubeProgrammer. Most of the time its not working, rarely it can read the data and erase. When it happens I am trying to program the memory and it can program ~400 KB then it fails. Then I used ST-Link Utility and it can program 9 MB of data without any problem, also it can read and erase. It is always working well but same .stldr file is not working in STM32CubeProgrammer. I will use it for TouchGFX so I need STM32CubeProgrammer to work well. How can I solve this? Thank you. By the way I asked another question about external loader, after being sure it will work with STM32CubeProgrammer I will share my driver code for MX25L12835F and STM32H7A3RITX under that question so anyone who needs those drivers can download from there.

Is there a way to reduce programming time with ST Link/V3?

I just installed en.stm32cubeprg-win64_v2-7-0.zip.Installation went without problems but when I try to start the application I get the splash screen and then it just exits apparently. If I runt it from a prompt I get no messages.C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin>STM32CubeProgrammer.exeC:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin>Is there a verbose mode or a log file to figure out why it does not want to start (windows 7 pro).

I have just started using STM32CubeProgrammer v2.7.0 and I liked the simple and great looking UI over the other programmers. Now I would like to use Automatic mode and expect the following:Erase the Read Out Protection (RDP) in OB or set it to "AA"Full chip eraseDownload the fileVerifySet the Read Out Protection (RDP) in OB to "BB"Can I do that? If yes how?Also could you please help me understand the OB command to set the Read Out Protection (RDP) in OB to "BB"?

As far as I can tell, cube programmer supports programming over CAN, but not FDCAN, like on the newest MCUs. True? Is there a path for STLink and cube programmer to support FDCAN?

Hello,I'm trying to update a micro over DFU (USB) mode since we don't always have access to the STlink programmer.I managed to start the unit in System Memory mode by reading a backup register at startup and jumping to system firmware if it's a certain value:/* Jump into bootloader if backup register 1 * has 0xB007104D written */ if(0xB007104D == RTC->BKP1R) { RTC->BKP1R = 0x0;   uint32_t JumpAddress = *(__IO uint32_t*)(SYSMEM_ADDRESS + 4); pFunction Jump = (pFunction)JumpAddress;   SysTick->CTRL = 0; SysTick->LOAD = 0; SysTick->VAL = 0;   __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH();   __set_MSP(*(__IO uint32_t*)(uint32_t)SYSMEM_ADDRESS); Jump();   while(1); }To be honest, I've seen similar flavours of the same code for this purpose.The thing is, the unit restarts in DFU mode, at least the PC says so: But DfuSeDemo won't give me the option to use it: However, it seems that STM32Programmer works: Questions:Can

Hello,I am trying to program Nucleo- H743ZI2 via UART (UART3) according to AN2606 doc page 244.I have managed to successfully program small bin and elf files. However, when I try to program a bigger file (bin = 655,619KB, elf = 5870KB) I am getting an error.Please note, that I succeeded to program this big file via ST-Link, during development and using the STM32CubeProgrammer . I only get the error using the UART programming interface.My STM32CubeProgrammer version is 2.6.0Log file is attached .Thanks

Hi.In a project I'm working on, I have to use external flash because the internal flash memory is low.I decided to use the MT25QU512ABB chip as it supports QSPI. After some research on the internet, I found the video of STMicroelectronics on youtube and followed the steps.Link:https://www.youtube.com/watch?v=XqCq0xtQmbI&t=608sI also downloaded the necessary files from STMicroelectronics' github page and created my project.but even though there is no error in my project and I load the .elf file in ST32CubeProgrammer without any problems, the program does not start.MCU STM32h750VBIDE CubeIDEI look forward to your helpthank you.

Hello everyone,I have a PCB with an embedded STM32F103 on it. The PCB provides access to some ports on the side. Those are linked to VDD, PA9, PA10, PA13, PA14 and GND. I tried connecting to it with Cube Programmer using a FT232RL as pictured below : The connections are :3.3 v -- VDDGND -- GNDRX -- PA10TX -- PA9When I try to connect with Cube Programmer it shows an error :I tried all baud rates as I have no idea which one I should use but still no luck.On the PCB it looks like pin boot 0 is connected to a resistance which is connected straight to ground and same for pin PB2.Any idea on what I am doing wrong ? (I'm fairly new to this so it might be a stupid mistake)Thanks in advance !

I'm seeing this in the console:Waiting for connection on port 61234... Accepted connection on port 61234...

Using STM32F412RGT6 on a board I've developed.having a problem using bootloader via UART (using CubeProgrammer).Following all described in AN2606.In my application, I'm using bootloader via UART1 (PA9, PA10).BOOT0 is High, BOOT1 is low while attempt to enter bootloader state.Board powered on.Choosing the UART in CubeProgrammer and selecting "connect"Get error:"Error activating device: KO.Please verify the boot mode configuration and check the serial port configuration"After disconnecting all other pins of the MCU, excluding power, SWD, RST, UART1 - CubeProgrammer works !!! :beaming_face_with_smiling_eyes: Start reconnecting all the pins I've disconnected, one at a time, in order to figure out which pin is the problematic one.Turns out that when PA12 is reconnected CubeProgrammer once again won't go into Bootloader.In my board PA12 is used as a UART (UART6_RX) to an external device.This external device is powered-off at the stage of trying to enter Bootloader.How does PA12 influenc

Hello,I am looking to be able to do in-the-field firmware upgrades with the STM32G071 board. I have used the STMCubeProg tool to be able to modify the nBOOT0 user bit with the ST-Link built into the NUCLEO board. What I am looking to do is to modify nBOOT0 to 0 through the firmware on the device. Then I am assuming that I can reset the device,and then using a connected UART comms, I can update the firmware, After that, I can set the nBOOT0 pin back to 0.The issues are that I can't figure out how to modify the nBOOT0 bit in the firmware. Also, I am unsure if my STM32G071 will be able to flip its nBOOT0 pin back itself after the firmware update. I have read through the AN2606 and AN3155 and cannot find an answer to my question. Everything points back to the STM32Prog tool which I don't want to have to rely on.

Hello all,I have written a External Loader using nucleo-l476rg and S25FL127 16mb NOR flash using 64k sectors. I was using it with TouchGFX and it worked just fine. I migrated to stm32l442. I have copied the code for the flash driver, changed the linker etc. as of this video https://www.youtube.com/watch?v=YFIvJVsvIsE The loader for the 442 does not work. It does not read or write in CubeProgrammer. I could put the memory into memory mapped mode, read and write to it when using the 442 when I debug the test code provided in the example. So the code is still good. My suspicions are that the 442 has only 64K of SRAM and this might be the problem. How can I fix this? Are there any other reasons for the loader not to work.Some notes:I can provide the code for the flash if needed. Also I want to use the 64k sectors so that my memory sectors are uniform. I am adding the log from the CubeProgrammer if it is of help:I don't think the problem is HW. I am running it on low frequencies, I have add

Hi, I'm programming my custom board using j-link. I want to use cube programmer but I can't connect. What should I do?

Hi, I have a couple questions about the future of the programmer. 1) Are you planning to add self updating at any time? 2) This is really close to being a useful programmer on the production line. Basically it needs a way to save a configuration for the program code and option bytes. Then be able to read in that configuration and program the flash and options bytes with one command. Any chance you will work towards this? Thanks,

I have installed STM32CubeProgrammer 2.7.0 on Windows 10 and it works fine. but when iam trying to run STM32_Programmer_CLI.exe even as admin it open and close immediately. the same thing happens by openning the STM32Bootloader.batCould anyone tell me please how to solve this problem?RegardsDepo

Hello, I was trying to set option bytes (BOR) with the ST-Link CLI (v3.6.0.0) for STM32G431, but it prompts that this feature is not available. With the ST-LINK Utility (v4.6.0.0) it is possible to set the BOR Level.I guess the ST-Link CLI is no longer maintained and you have to switch to the new one (Cube Programmer CLI), is that correct?Thank you for your information!

I have a NUCLEO-F207ZG board and STM32CubeProgrammer v2.7.0. I would like to use the embedded bootloader located in system memory. So, first I activate bootloader mode pulling-up pin 138 (boot0) of the MCU. Then, in order to verify this first operation, I connect NUCLEO-F207ZG board to STM32CubeProgrammer via ST-LINK/V2-1 interface. The board connect succesfully and if I browse in the MCU Core menu I can see the Program Counter value is in the system memory range address. My next step is to disconnect NUCLEO-F207ZG board from the STM32CubeProgrammer and to select the UART interface (configuration is shown in the attached image) . When I click the Connect button, I get the following message error (see also the attached image):Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...I tried resetting the board, but it didn't solve the problem. Could you tell me please how to solve this proble
