STM32CubeProgrammer (MCUs)

..

we are developping sensor reading board which has stm32l412 AND stm32l476RG on it. we could write program to stm32l412 through CubeProgrammer without any problem but we couldn't write to stm32l476. Please addvise possible cause. Both STM32l412/476 has exactly same usb interface/circit for each. CubeProgrammer find usb port for stm32l476 and communicate by 12MBit/sec.But same CubeProgrammer can't find USB DFU on stm32l476.windows10 also popup alert of no device recoganition we confirmed reset procedure (Boot0 and Boot1) is OK.Host=windows10CubeProgrammer ver =2.12.0

I am using an open bootloader from st for the firmware update in my project. Bluetooth module is connected to MCU via UART, which is configured to communicate with the computer via SPP protocol. Basically, I am able to communicate with the MCU like a serial com port.I want to know if I can use the stm32cubeprog UART feature to upload the firmware on the MCU running ST Open Bootloader? ST Open Bootloader: https://github.com/STMicroelectronics/stm32-mw-openbl

My MacBook Air (M1, 2020) macOS Big Sur version 11.5.1 (20G80) struggles with STM32CubeProgrammer. I deinstalled all my java updates and installed the recommended java version according to this post https://community.st.com/s/question/0D50X0000BmnqrBSQQ/how-to-run-stm32cubeprogrammer-on-macos-catalina-10151-19b88.My java -version: java version "1.8.0_231"Java(TM) SE Runtime Environment (build 1.8.0_231-b11)Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)The app boots up and reads my link V2 version which is V2J38S7 now which is great, but sadly whenever I have my connection option as "ST-link" then I click "Connect" or "Read" STM32CubeProgrammer immediately crashes. It doesn't however do that under options like "UART" or "USB" it simply reports back that I haven't got that type of connection established then reverts me to the main menu without crashing. My ST-Link V2 has a steady red LED plugged into USB-C port via USB-A to USB-C adapter. If CubeProgrammer is somehow br

OS : windows 10 home 64bit​stm32programmer version : 2.9There is a ".hex" file in the dropbox or onedrive path.Downloading to mcu flash forces stm32programmer to quit. If the ".hex" file is not in the dropbox or onedrive path, it is downloaded normally.This problem occurs from the version with built-in jre in stm32programmer. (v2.7 or higher)Versions below 2.7 will not be terminated.I tried several methods, but it doesn't work.Please help.

Hi Everyone,I have a STM32L1 connected via USB in DFU-Mode.I'd like to write EEPROM, but trying to do so results in "Memory Limits Error".Using old DfuSe 3.0.6., this is possible... What am I missing? Is CubeProgrammer at all capable of writing EEPROM?Thank you!

I have written a small driver code for the same to store different types of data types to a memory location.The link to my code is: Yadnik1/Eeprom-Emulation-driver-STM32 (github.com) and I have taken reference from here: STM32/FLASH_PROGRAM/F1 SERIES at master · Reference Blog: How to Program Flash memory in STM32 » ControllersTechThe available code was for STM32F103C8T6 microcontroller, and I had to make some changes to the code for my g0 series MCU. It would be very helpful if someone can please tell me what mistake I am making. Thank you very much!!!

Hi,I am using STM32L071 micro controller for my product. We planned to flash the code using USART communication. The USART1 from MCU is connected to embedded system ( Nvidia Xavier NX ) using USB to UART converter. Then the MCU is put into boot mode by setting BOOT0 pin HIGH. I confirmed that the MCU entered bootloader mode by connecting ST-Link V2 with the MCU and ensured that the PC pointed to the bootloader address(0X1FF00B38) of the STM32L071 series as shown in the image belowAfter entering system memory mode, if I try to flash the code through UART using STflash tool from Source Forge , I was not able to flash the code. Error shown by the program: Timed out.Can someone please guide me what I am missing here?

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,

I am using an STM32f030C8 with External Flash (W25W128) Via SPI, and want to program the extern flash with sound data using STMcubeprogrammer.I found an excellent article (https://community.st.com/s/article/how-to-add-your-spi-flash-into-the-stm32cubeprogrammer-external-loader-part1) that used a RAM based approach.My question is can external loaders be a FLASH based program, and will STMcubeprogrammer load the external loader to allow programming of the extern Flash and then after that load the CPU flash with the real application code ?

Hello,even though I have selected an external QSPI loader, at "Erasing & Programming" the firmware is not uploaded to the external memory, the programmer loads it to the internal memory.Why this?Thank you 

Hi, I'm trying to develop a bootloader. I managed to jump to a program properly when it's already in the flash. I managed to program the flash but then I can't jump to the newly loaded code. Worse, when I add the "HAL_Flash_program" to my code, even when not using it I can't jump anymore. I'm struggling to understand why. Could you please help me ?I can do both in separate programms, first loading the code and then jumping to it and it works. I checked with stm32cubeProgrammer, the code in flash memory is verified as the file i'm uploading.My MCU is a STM32L4R9AI, and i'm using the discovery board and stm32cubeIDE. Please find the code here.

Hello !I'm currently trying do make my own external loader for my board Mikromedia Capacitive 7.I have a STM32F746ZG MCU and the SST26VF064B 64Mbits Flash Memory.I want to make my external loader in order to store images in my external flash.I made debug on my Loader_Src file, Init(), Read(), EraseSector() functions work perfectly.However when I launch my external loader in STM32CubePrg to read my external flash, I fell into a timeout like this : Here are how my Loader_Src functions are mapped in my RAM :The PC value is my Init address, so I expected it to work but not yet !I have no idea where the error could be from, maybe the RAM mapping, the linker script..I could post my Loader_Src file or more details if you need.

Is it possible to use Segger probes in STM32CubeProgrammer?Or is it planned in the future?

Hi! I'm using STM32CubeProgrammer v2.10.0 under Windows 10 Pro 21H2 x64 (Build 19044.1766) and when starting to flash devices in automatic mode, CubeProgrammer flashes normally the 1st device with messages only in the log, but starting with 2nd and further it outputs not only the log, but also a bunch of pop-up messages such as "Download verified successfully", "File download complete" etc. See the screenshot below. They all stackup on top of each other and it's impossible to use the software unless you close them all. One can certainly hold the Enter key to close them all really fast, but it is still very annoying.

Could someone to give a link to an "Linker Code" about which is mentioned in paragraph 12 in this tutorial https://community.st.com/s/article/how-to-add-your-spi-flash-into-the-stm32cubeprogrammer-external-loader-part1

Hello everyone,I have made a custom board with STM32L072CBT6. All works fine when i use my board and program her with STLink.I would try to program my board through USB, to do that i have a uUSB connector on my board connected to my uC. To flash, i use STM32CubeProgrammer.1 - I succeed to detected my bootloader on my peripheral (press reset and boot0 button)2 - I succeed to acces to my board through USB with STM32CubeProgrammer 3 - I chose my .elf file to download and when i try to download, i have this folling error : 15:24:46 : Error: Write failed at address: 0x8001000  15:24:46 : Error: failed to download Segment[0] 15:24:46 : Error: failed to download the File"Write failed address" change when i try multiple time to download and sometimes it's works.Do you have advice help my about this problem ?Thanks for your help,Best regards,Lam

Recently I used Stm32cubeprogrammer to write programs via UART. I can connect to the MCU, I can also read the data, but the download fails.Have you encountered similar problems? 

If so, I seem to be missing how to set boot0 (I think) to have STM32CubeProgrammer v2.11.0 recognize the part on the dev board, “No STM32 device in DFU mode connected�? although I can use CubeIDE to program the development board. Just looking for a solution to program and update the code in the part without using CubeIDE. We want to use the USB interface just like when using the CubeIDE, the STM32G071 will be on a PCBA that will be connected to a system via USB for updates.

Don't have a eval board currently, waiting for order to arrive.Can anyone tell whether CubeProgrammer and other popular tools will properly detect that F7 is in dual bank mode, so it has a different number and size of sectors?Can these tools set the option bit that enables dual bank mode and flash the data in a single programming pass, or first we have to enable dual bank, disconnect, connect again and flash the data?
