STM32CubeProgrammer (MCUs)

I tried connecting BOOT0-3.3 V and PB7,PB6-RX,TX or PA10,PA9-RX,TX, but I get an error every time. What am I doing wrong? I also tried other speeds and holding RESET, but nothing helped.

As title. In order to test the external loader algorithm, I add a test data to a QSPI project that can be excuted correctly when downloaded to the internal flash. The test data will be written in the external flash via the external download algorithm.There are two algorithms in the QSPI project, one is for internal flash and the other is for external flash The setting of target option in the QSPI MDK project is shown as following: And the scatter(QSPI.sct) file is shown as following:; ************************************************************* ; *** Scatter-Loading Description File generated by uVision *** ; *************************************************************   LR_IROM1 0x08000000 0x00100000 { ; load region size_region ER_IROM1 0x08000000 0x00100000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) .ANY (+XO) } RW_IRAM1 0x20020000 0x00060000 { ; RW data .ANY (+RW +ZI) } }   LR_ROM1 0x90000000 0x02000000 { ER_ROM1 0x

I have downloaded the latest version of Cube Programmer and updated my ST-LINK/V2 firmware. I've tried to program connect with a target I have designed and the target cannot be found. Clearly I need to find out why, but that is not my question. Rather, after this, the Cube Programmer application will not close, nor can I find it in TaskManager to kill it! Is this a known bug? Having to restart my machine each time this happens is a pain. (BTW using windows 10Many thanks

We have the following situation, such that the UART is translated by the FPGA from a half duplex RS485. Can the stm32cubeprogrammer be used in such a way? what is required from the FPGA? or the MOXA driver operates in such a way that it is transparent to the software?

When using the Nucleo board with the STM32H743 (Rev V) I can trigger a DFU event within software and using the STM32CubeProgrammer it can detect the presence of the board in DFU mode - so far so good. When using my own design (using a Rev Y part) I cannot seem to get the STM32CubeProgrammer to detect it.In my design, I am using a regular USB type-B socket (the Nucleo uses a micro type-B), with USB_OTG_FS_DP and USB_OTG_FS_DM on PA12 and PA11 respectively; I have USB communications using the CDC, the same as how it was configured for the Nucleo board. Having read that the bootloader looks for the presence of the cable I've connected PA9 (USB_OTG_FS_VBUS) still to no avail. Is there something I'm missing?Just to add, the routine I'm using to call the bootloader can be found at https://community.st.com/s/article/STM32H7-bootloader-jump-from-application

Hello all, I worked with the Nucleo-F429ZI (which includes the STM32F429ZI) at the project start. I updated my software via UART and do following steps:I connect the Nucleo-F429ZI via USB to the PC (it's the power supply too)I connect a MM232R to pin PA9 and PA10 (UART1) and GND.I connect the BOOT0 pin to 3V3I press the reset button B2I start the tool "STM32CubeProgrammer"I choose UART and my MM232R, set the baudrate to 115200 and the parity to evenI connect the MM232R load the new software and disconnect the MM232RI remove the connection of BOOT0 and 3V3I press the reset button B2The new software works!Then I designed my own PCB with the STM32F429ZI. My software works on it and I can update it with the STM32CubeIDE and the SWD connection (PA13 and PA14). Now I want to update the software via UART and the bootloader:I have two leds which blink during my hole software. If I connect BOOT0 to 3V3 and reset the mikrocontroller the leds don't blink any more. So I think the mikrocontroller i

Hi all.I've created an external loader for a custom STM32H743 board with external W25Q64 FLASH (MCUDEV DevEBox H743). The project works really well when I'm testing on CubeIDE. When exported to .stldr inside CubeProgrammer I can upload a 1MB file to the external FLASH, but the returned data when reading is incorrect. It always shows 0x99999999 for all the data.If I switched to another loader made by @Community member​ for the same board (view it here), data returned is as expected, so I'm pretty sure data has been written correctly.What could be the problem? Read operation is managed directly by CubeProgrammer and dummy cycles are configured conform the datasheet. Any Idea?Thanks in advance!

Hi, I am facing up Error: Data mismatch found at address error. I have tried to decrease the frequency, also make a modification to the linker script. Also, I used OCD. But, no success. When I open a new project it uploads. Whenever I change something in code, it goes even if I change to back the code. Could you help me?I am working on STM32F030C8Tx, and using stm32f4-disco st-link.

We have custom hardware with STM32F746, and having issues getting factory bootloader DFU USB working. When I run STM32_Programmer_CLI -l usb command, I can see my device (although Serial Number looks wrong).When I try to connect with STM32CubeBootloader (tried V2.1 and V2.2), I get the following errors:16:19:53:063 : Error: Uploading Option Bytes bank: 0 failed16:19:53:091 : Error: Initializing the Option Bytes failedMy board has a 24MHz external crystal. Does anyone know what the issue might be?I think the correct drivers are installed.

Hi there,I've an issue when trying to automatize the SWV command with Jenkins. The issue is that when I run the command: STM32_Programmer_CLI -c port=SWD -swv freq=216 portnumber=0 it asks the user to press 'R' in order to start. Since Jenkins has no desktop or interface I cannot focus the window in order to press the button with a macro. I have tried with a tubed batch, python script and keyboard macro but nothings seems to work. So I guess my question is, has anybody done that? Is there any way I can pass the 'R' as a parameter in the command line?

Hello everyone!I work with a Nucleo board F446RE. One month ago i lended my board to one of my university collegue. After a while he gave me back my board, but i can't use it anymore. When I try to flash a program with STM32Cube IDE it gives me an error saying:Error message from debugger back end:Error finishing flash operationI find out that my collegue in some way activated the Read Out Protection, and I no way can disable it. I tried to erase chip memory with STM32 ST-LINK Utility, no way, I tried to change Option Byte from level 1to level 0, no luck, I even tried to change the Option Bythes with STM32 Cube Programmer (in RDP section i have FF) and write AA but even that didn't lead to success.I'm desperate and don't know what to do. I've done a thousand of research in all types of forums no dice!Anyone who can help me out?

I changed the microcontroller from STM32F733ZEI6 to STM32F723ZEI6 and it stopped working.When connecting with the debugger (STM32FcubeIDE)・STM32F733ZEI6 was able to connect.・STM32F723ZEI6 was disable to connect. and The following error occurred(Details are attached).Error: failed to download Segment[1]Error: failed to download the FileWhat should I do?

IMHO we don't need running CPU core or clocking on it for example....Thank youRalph

 Error: No STM32 target found! This is the CONSTANT message I get from the STCUBE software. I can see reference voltage from my board but actually connecting to the chip is impossible  Error: No STM32 target found!,  Error: No STM32 target found!, Error: No STM32 target found! I don't understand what the problem is; I just want a single access event via SWO pins so I can woosh the firmware onboard. My developer uses some kind of el cheapo Chinese clone so can't advise me as to why using the official ARM kit is proving to be such a pain. Accessing PDI pins on an ATMEL chip is something I can do in seconds using ICE/Studio.... what's the secret to the ARM equivalent?Thanks

Hello,I have problems installing the Cube Programmer. During installation it fails to execute some batch files (first one "populateApi.bat"). If I continue installation anyway, the installed Cube Programmer can't be opened and can't be uninstalled, only manuall delete was possible. First tried with 64bit version, same problem with 32bit version.My windows system is just a few days old, maybe some simple pre-requirements/installations are missing? I installed the Java Runtime Environment, but it didn't solve the problem.This is the error log from Cube Programmer installation.com.izforge.izpack.api.exception.IzPackException: An error occuredin java.lang.Thread.run() at Thread.java:748in com.izforge.izpack.installer.unpacker.UnpackerBase.run() at UnpackerBase.java:241in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:319Caused by: com.izforge.izpack.api.exception.InstallerException: File execution failedin com.izforge.izpack.installer.unpacker.UnpackerBase

Hi,I'm having some trouble with getting my (genuine) ST-LINK v2 detected in the STM32CubeProgrammer. The strange thing is, the STM32CubeIDE and also the firmware update utility detect the ST-LINK v2 without any issues. Already tried different USB ports. No success so far.What's the problem and how to solve this issue?The following versions are installed:STM32CubeProgrammer v2.6.0STM32CubeIDE v1.5.1ST-LINK v2 Firmware V2J37S7Windows 10 (20H2 - Build 19042.804)ST-LINK Device Driver v.2.1.0.0 by STMicroelectronicsThanks

 I am trying to restore the demo file that came with this discovery kit. Erase all works but when I try to program it I get these errors after the erase is complete: 17:48:08 : Download in Progress: 17:48:11 : Error: failed to download Segment[9] 17:48:11 : Error: failed to download the FileUsing ver 1.6 of the programmer. If I try to load something smaller it always fails in a different segment. Board tries to operate with partial download but gui is distorted etc.

Hello folks,I recently bought a stm32f410rb nucleo board and configured it in Linux(Ubuntu 18.04) using eclipse ,CUBEMx, IDE and programmer.Once build is through, I tried downloading the program and the verification is failing here.Could anyone direct me how to resolve this issue?

I can successfully program a STM32L082 over USB when using STM32_Programmer_CLI.exe but not using the GUI. I can see the device under USB but I get "Error: Data read failed" followed by "Warning: Connection to device 0x447 is lost" when clicking the connect button. I have previously had no problems using this method on the same board (possibly with an earlier version of STM32 Programmer).

Hello! I'm writing data to flash and ran into an odd anomaly where the data is erasing itself on reboot. I have one program writing data to flash and another reading and it keeps reading back nothing. I ended up writing the data using one program and then reading the data using the STM32CubeProgrammer. First read shows my data. When I disconnect and reconnect, it's all gone again. My current code is fairly simple. I have a flash location with 10 pages set aside:/* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 40K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 106k FLAG_VAR (rx) : ORIGIN = 0x8015800, LENGTH = 2k LOC_VAR (rx) : ORIGIN = 0x8016000, LENGTH = 20k }I am currently only using 1 page for testing purposes though. I am effectively erasing the flash and then counting up in the byteArray by 1, then writing 2048 bytes (one page). It seems to be working ok (as I mentioned, it's writing correctly, it's just erasing it a second time). Unfortunately, I'm
