STM32CubeProgrammer (MCUs)

HiThis is my first post on this Community. I am not sure I am getting in the right place for questions. If this is a wrong one, please let me know where I can find for help.​I am working on my own console project with VS2019 Community VC++. I have followed the example "STM32CubePrgApi" to have all settings done on my console project. I could compile it without error. But, when I ran it with debug on, I ran in to an exception​"Exception thrown at 0x0000000000000000 in MCP2221Demo.exe 0xC0000005: Access violation executing location 0x0000000000000000."​This exception looks like a NULL exception to me. The code I was getting this exception is​"int uartConnectFlag = connectUsartBootloader(uartParam[2]);"​I peeked uartParam[2] and got uartParam[2].portName = "COM6". This meant that there was a serial port COM6 but was not allowed to access.​By the way, with same codes above, I could run nicely on "STM32CubePrgApi" example.​General project settings for both projects are​Windows SDK version​

Recently I'm using STM32G051 and try to write flash via i2c bootloader.Below are my steps:Use STM32CubeProgrammer to set nBOOT0_SEL = 1 / nBoot0 = 0 /nBoot1 = 1 to enter BL modeDisconnect ST link, and use i2c host tool (Aardvark) to send i2c write (no-stretch) command 0x32, 0xcdRead 1 byte, get ACK (0x79) frame successfully.Send 5 bytes start address(0x08000000) with XOR checksum (0x08)Read 1 byte, get ACK (0x79) frame successfully.send 10 bytes writeLength(0x08), data(0x11,0x22,0x33,0x44,0x55,0x66,0x77,0x88), checksum (0x80)Problem here!! read 1 byte and expect to get ACK(0x79) or BUSY(0x76), but I saw CLK is stretched at 9th bit of address phase:I've checked all read/write protection are disabled via STM32Programmer, and I can access read flash and erase flash successfully, only write process fail. Is any one have encounter similar issue and tell me if my procedure is not correct?Many thanks.

This problem is driving me crazy. I'm running STM32CubeIDE, Version: 1.9.0, Build: 12015_20220302_0855 (UTC) connected to a NUCLEO-L4A6ZG. Very frequently, my debug sessions go like this:  STMicroelectronics ST-LINK GDB server. Version 6.1.0 Copyright (c) 2022, STMicroelectronics.

For production we need an uploading scheme without any user interaction (no reset, power cycle etc.) except USB insert. Is this possible?What I have tried so far:The (empty) controller starts up into STM32 bootloader the first time (boot pin = 0). Connecting via CubeProgrammer CLI (USB) and flashing the application is no problem. Sending a start command does nothing. Sending -detach raises an error. But: changing any option byte will reboot the controller and it will than execute application as expected. The problem with this is that the option byte programming ends with timeout error - because reading back fails - the controller directly starts inbetween.Best regards,Sven

Programming my board worked fine for a long time, but then it started to fail with the error messages shown below but I could get it working again by closing the IDE (STM32CubeIDE) and unplugging the ST-Link/V2 then plug in and restart the IDE - but now I can't get it to program even once - so it was not a sudden failure, it was a gradual deterioration.The IDE was updated at least once and the project was migrated before the failures started (I think).I have tried installing the IDE on a virtual machine then recreating the project - didn't work.Tried installing the IDE on another machine that had never had any ST stuff installed on it - didn't work.Tried creating a new, small project - didn't work.Interesting that installing the IDE on another machine doesn't reset the problem - I would have expected a new installation to not have the problem and that the problem might reappear as it did originally, but it doesn't - the problem is at the same stage of deterioration as it was in the ori

Im trying to jump to bootloader section from my Code. I'm trying to update the firmware over USART with the intergrated bootloader. In my application I'm using USART2 (PA2/PA3) on a STM32L431CCU6 Microcontroller running native FreeRTOS. My Code to initialize should work: // Set Memory Boot Jump address SysMemBootJump = (void (*) (void)) (*((uint32_t *) 0x1FFF0004)); //device dependent parameter System Memory + 4   // Set Display to Firmware Update Mode display_show( FW_UPDATE );   taskENTER_CRITICAL( ); { // vTaskSuspendAll( );   // Turn off Peripherals HAL_TIM_Base_MspDeInit(&htim15); HAL_RTC_MspDeInit(&hrtc); HAL_UART_MspDeInit(&huart2); HAL_UART_MspDeInit(&huart1); HAL_SPI_MspDeInit(&hspi2); HAL_SPI_MspDeInit(&hspi1); HAL_CRC_MspDeInit(&hcrc);   // Disable Interrupts __disable_irq();   // Remap Memory __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH();   // Reset Systick timer SysTick->CTRL = 0; //r

Hello,I am following a tutorial to use AWS on my B-L475E-IOT01A board. When trying to program the board using STM32CubeProgrammer, it crashes when I click "connect" in the upper right hand corner. Sometimes it allows me to connect, but then crashes when I click on the "Erasing & programming" tab.The program worked just fine the first time I used it to program the board, but this issue started happening after programming the board only a few times.I am using STM32CubeProgrammer v2.13.0 on Ubuntu 22.04.2 LTS. The error log is pasted below:## A fatal error has been detected by the Java Runtime Environment:## SIGSEGV (0xb) at pc=0x00007f32916f5f2a, pid=2899, tid=0x00007f3281fc1640## JRE version: OpenJDK Runtime Environment (8.0_265-b01) (build 1.8.0_265-b01)# Java VM: OpenJDK 64-Bit Server VM (25.265-b01 mixed mode linux-amd64 compressed oops)# Problematic frame:# C [libstdc++.so.6+0xf5f2a] std::basic_string<char, std::char_traits<char>, std::allocator<char&g

Hi, StM32CubeProgrammer shows up realy tiny on my Linux laptop screen (2560:1600), please see screenshot.Something similar happened to STM32CubeMx inside the IDE, I could fix that starting the IDE withGDK_DPI_SCALE=0.5 GDK_SCALE=2 /opt/st/stm32cubeide_1.7.0/stm32cubeideHow to display the Programmer with a reasonable size? The text is almost impossible to read.Thanx for any help!

We deliver encrypted image to the customer-manufacturer. After image update is performed the image is stored opened in internal flash. With RDP level set to 2 it is possible protect from jtag debugging and access. But if hacker at manufacturer side, writes it's own application (both desktop and ST part, residing in SRAM, or even one of internal flash banks) to read internal flash, what kind of physical protection on ST MCU side can be applied at this stage? Assume experienced hacker can write it's own "CubeProgrammer tool", which would read internal flash. How flash can be protected from that?

Hi everyone,I have a st-link v2 with the STM32cube programmer on a windows 10 PC. My target is a ISP30301 ( nrf 518222) . If i try to connect to the target , it says "Unable to read device id from ROM table". (after the hardware reset is done) . What could be the problem ?Thanksthe log is 19:05:47 : ST-LINK SN : 50FF7006726653555440196719:05:47 : ST-LINK FW : V2J37S719:05:47 : Board    : --19:05:47 : Voltage   : 2.95V19:05:48 : SWD freq  : 4000 KHz19:05:48 : Connect mode: Power Down19:05:48 : Reset mode : Hardware reset19:05:48 : Error: Unable to read device id from ROM table19:05:48 : Error: Cannot identify the device

I have STM32CubeProgrammer v2.13.0 and I want to enable dual-bank flash memory on my F7 microcontroller (which supports this configuration) via the option bytes.However, there is no such option byte available to enable dual-bank mode. How should I enable dual-bank mode if the option byte isn't available?

Hi !I'm using STM32CubeProgrammer v2.12.0 (according to the updater it is the latest at this time) and I want to enable Dualbank on my Nucleo board.The Nucleo board is a NUCLEO-L476RG and is correctly recognized as such: However in the Option bytes -> User Configuration tab, the DUALBANK option is missing: The BFB2 option is present though, but as I understand it:DUALBANK controls whether or not the flash is divided into 2 banksBFB2 controls which bank to use in case DUALBANK is setAm I right ?In any case, shouldn't DUALBANK be shown since it is user configurable ?Thanks in advance !

Hi, I am currently asking help to flash the BLE module of my card. I think I have two problems. The first one is hardware. I tried to connect CN5 with STLink V3mini. I think that the connection of wires is correct. And then, when I plug my STM32 and my STLink on my laptop and I try to connect my card through STM32CubeProgrammer, I get an error : STM32 target not found.When I connect two USB devices, my laptop is not able to get connected to STM32.So, this is my first problem.And the second is that on STM32CubeProgrammer, I don't have the field "Firmware Upgrade Service" available, while I have the version 2.12.0...Does someaone have an idea to upgrade the firmware, because I tried to do it in the field "Erasing & Programming" but it didn't work...If someone could help me, or think about getting an issue, I will appreciate so much !!

am trying to connect stlink v2 debugger with stm32f413 mcu hardware in Cube programming sotwaream getting Error: Cannot connect to access port 0 If you are trying to connet to a device with TrustZone enabled please try to connect with HotPlug mode

Hello thereAs per document UM2237, I am using command:STM32_Programmer_CLI.exe -c port=SWD index=1 mode=HOTPLUGto connect to the device. Successfully, device is connected.In case of reading a specified memory, one uses e.g. command:STM32_Programmer_CLI.exe -c port=SWD index=1 Fast mode=HOTPLUG -r32 0x20000000 0x00000002Which works as a charm. However... these command (directly taken from ST UM2237), issue a connection each time a read is issued.Of course I tried with only command:STM32_Programmer_CLI.exe -r32 0x20000000 0x00000002However the "Error: connection to target must be established first." pops up.Here bares the question. Is it possible to connect to target only once and then trigger some readings, without reconnecting each time?Thank you!

Hi Everybody,Firstly, I would like to note that I am pretty new to embedded systems, so I am sorry if my terminology is off or if I am not communicating clearly, please forgive the (probably) gaping holes in my knowledge. I will do my best to communicate my problem as clearly as I can. I am working with a STM32L412 on product development, the team I a part of would like to have a section of flash not be erased when the MCU is reprogrammed. The amount of information that we need to be preserved is small, maybe at most 200 bytes, enough space to store some information like a serial number, baud rate, etc.To that end, I currently have sectioned off the last page (page 63) of flash in my L412 in the linker file to separate it from the rest of flash, so I can use it to contain this information. //This is what I have so far in the linker file. RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 40K RAM2 (xrw) : ORIGIN = 0x10000000, LENGTH = 8K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 126K Devic

Hello lovely people,I seem to have run into a headscratcher that I can't get out of.I have a NUCELO-U575ZI-Q that I've carried out the following steps on:Connect board to PCConnect with STM32CubeProgrammer Normal Mode, 24000KHz, SWDUncheck UNLOCK_1A in the Option Bytes Screen.Disconnect and reconnect within STM32CubeAttempt to Check UNLOCK_1A to reverse the protectionEncounter the following error:I've also tried using the CLI and can't get any different results, am I missing a step to be able to reprogram the option bytes?Thanks in advance for your help!

In my organization we have developed a few docker images so that any developer is able to quickly get a working development environment having all the needed tools (e.g. compiler, debugger, static analysis tools, utilities, programmers, etc.)A very useful tool to have is the Cube Programmer, especially the cli version, to have the official application to program microcontrollers.However at the moment it is not easy to include it inside a dockerfile, because I could find no permanent link for download, and manual operations are required to download it and install it, defeating the purpose of a ready to go environment which is what we want to obtain.At the moment we've been using other programmers (e.g. pyocd or texane/st-link) but for some specific things (e.g. unlocking, option bytes) the cube programmer is more reliable and would be nice to have.So my question is, is there a way to have a permanent link for downloading the cube programmer, so that it can be easily downloaded and insta
