STM32CubeProgrammer (MCUs)

Hello,I followed the STMicro YouTube tutorial for developing an external QSPI loader. I am using the W25Q128 attached to the NUCLEO-H7A3ZI-Q. The flash is working fine with my driver using the test program "main_test.c" provided with the tutorial, and I can access the flash contents at 0x090000000 in memory-mapped mode from the STM32CubeIDE debugger. I compile the external loader with the linker script provided in the tutorial and move the .stldr file into the external loader folder for STMCubeProgrammer. I select my loader from the list of loaders, but when I try to view external flash contents at 0x090000000, I get data read failed. If I try to download data to the external flash from STMCubeProgrammer I get:16:35:41 : Time elapsed during the read operation is: 00:00:00.00916:35:50 : Memory Programming ...16:35:50 : Opening and parsing file: testbinary1M.bin16:35:50 : File : testbinary1M.bin16:35:50 : Size : 1.13 MB16:35:50 : Address : 0x0900000016:35:50 : Erasing memory correspondin

While reading the UM2237 (STM32CubeProgrammer software description - User manual) data, I came up with a question.The FUS/Stack upgrade order is explained in Table of Contents 2.7 Flash the co-processor binary using graphical interface. Do I have to connect via ST-Link to do FUS/Stack upgrade?I tried to do Firmware Upgard using the USB bootloader, but it didn't work.Also, when connected via ST-Link, all the WB Command buttons are activated, but when connected via USB, the WB Command buttons are deactivated.question1. Is it possible to use Firware Upgrade Services using a USB bootloader?2. Can't use WB Commands button when using USB bootloader? Specifically the Start Wireless Stack button

When I try to communicate my STM32L4P5-DK through SPI protocol. I fed the MOSI and SCK pin to the oscilloscope and checked the output there I got several doubts1) when I send a data 0xAA to the slave ( HAl_SPI_Transmit(&hspi2,0xAA,1,10) ) with the baud rate of 187.5kBits/sec the time period was 5us app(each bit is shifted at falling edge as per my configuration) but here MOSI otput is not as expected      2) when I try to send 0xFF the expected MOSI output is the MOSI pin should remain high for 8 falling edges of SCK but it was not that I got on the scope.The below picture shown the 0xFF data in  MOSI(Yellow) and SCK (Green) 3) also the SCK is not a continuous signal, SCK  maintains 0 for each 8 cycles with a regular period of time why? 

 HiI am using STM32WB55RG board and trying to run example code BLE_HID When I connected via ST-Link using the STM32cubeprogrammer tool, the binary I wanted was uploaded well as shown in the picture below, and I checked the Bluetooth operation by executing the BLE_HID code.  However, when connected via USB, as shown in the picture below, the binary I want is not upgraded and the tool is shut down. Occasionally, the binary is uploaded, but in that case, the WB command buttons are disabled, so I can't press Start Wireless Stack, so even when I run the BLE_HID code, it doesn't work well. In the BLE_HID example code, MX_APPE_Init(); When the function is executed, when the static void APPE_SysEvtReadyProcessing(void * pPayload) function in the app_entry.c file is executed, it is divided into Wireless_fw_running or FUS_fw_running.When the binary is upgraded using USE as a soft loader, fus_fw_running is always executed.I want to run it with wireless_fw_running.  &

Installation of all STM32Cube software on Macs is problematic and appears to poorly supported. Suspect that's a market share problem vs. Windows.  But that's a topic for a more thorough discussion elsewhere. (I responded to a recent automated survey with a request to contact me for a full discussion.)In this particular case, I'm installing STM32CubeProgrammer from en.stm32cubeprg-mac-v2-14-0.zip.  No installation guidance (either a Startup doc or README file) packaged in the zip as normally expected.After several failed installation attempts (based on prior experience installing STM32Cube apps, e.g., Running the ,app installer from the CLI or changing file settings using xattr, I did a careful review of Programmer documentation.  So I finally found macOS Installation instructions in paragraph 1.2.3 on page 12 of the UM2237 document (notably nowhere nearby when I was in the middle of the installation process).The normal procedure outlined there failed.  The

I have read a lot of threads on different forums regarding my issue but non of the solutions were able to help me out.I have a STM32F469 Discovery board and I am unable to connect to it. I initially tried building a program on STM32Cube IDE and putting it in debug but was unable to as the error said no target detected. After researching on the issue, I came a across a forum that linked to this page which reasoned out the issue. But this solution also did not help. I have attached an image of the STM32CubeProgrammer alongside to highlight my setting.PS. I noticed that when I set the Reset mode parameter to Software Reset and click Connect. The parameter changes from Software Reset to Hardware Reset. I am not sure why this happens. Could you explain this also to me?Thank you.

Hello, I'm currently working on controlling a board with an integrated STM32WB55VGQ6 chip. While running the BLE test example code on the STM32WB55, I was able to confirm that Bluetooth functionality is working.However, when I tried applying the same code to our custom board, it didn't work as expected.During my research, I came across information that the Arm Cortex-M0+ (CPU2) can't be written to directly by users. As a result, I downloaded the "Patch for STM32CubeWB" for M0+ and obtained BLE-related binaries from the STM32WB_Copro_Wireless_Binaries folder.I'm curious to know which binary is the default one running on the M0+ core of the STM32WB55 board. Furthermore, when I connect my board and access the Firmware Upgrade Services menu in STM32CubeProgrammer, I specified the File path and Start address before pressing the Firmware Upgrade button. I was able to confirm that the Stack Version was successfully uploaded.However, I've noticed that the WB Commands buttons are inac

Hi every one,I read bin/hex file from stm32f103c8 MCU and saving it, then I erase the MCU and burning the same bin file which I read in the previous stage, the MCU does not work as before.can you help me please

Hi,I have a situation where I can successfully program the target using STM32CubeProgrammer, but it fails when I try to do the same with STM32_Programmer_CLI.exe with an error:Error: failed to erase memoryBoth are v2.13.0.The command line I used:STM32_Programmer_CLI.exe -c port=SWD -d "firmware.bin" 0x08000000 -vb 3Attached are the verbose level 3 output from each. I am attempting to figure out why STM32CubeIDE fails to download code for debug. It also encounters the same failed to erase memory error. Appreciate any help anyone can give me. Thanks.

Hi  I am having issues with programming a target board with a genuine ST-Link board (got from Farnell) . I have been using a cheap programmer that works, and as I have upgraded to the new IDE (from atollic) it fails to work , but still works on the STM32CubeProgrammer. The genuine ST-Link communicates with the PC, but cant connect to the Cube Programmer, while the cheap one works perfect. I have set the ST-Link Configuration to the below.I also have the images from the logic analyser during a connect sequence. As this is on the same target board and the cheap one work, I think this points to an issue with the genuine programmer. I managed to get a loan of another genuine one, and that too has the same effect. A noticeable difference the serial clock starts before the Reset line goes low , unlike the genuine no clock  till a good while after the reset line , and I assume it times out before this. Anyone any idea, I am totally baffled. I checked all the voltages on the board an

Hi  I have been using Atollic for years , with the cheap stlink programmers from AliExpress. I havent had any issues, but just recently updated to STM32IDECube (V1.13.0) , and STM32CubeProgrammer (V2.14.0) . I purchased an original ST32Link-V2 , but unfortunately doesn't connect through either STM32CubeProgrammer  or STM32IDECube. The cheap version works on STM32CubeProgrammer but not STM32IDECube , comes up "error No ST-Link Detected " (same error STM32IDECube for genuine).  I am using pins:SWDIO , SWCLK , GND . I also tried the Reset line on the genuine , but still error. On STM32IDECube  I get "No ST-Link Detected.." on both the cheap and genuine one. On the STM32CubeProgrammer  works as expected with the cheap one, with the genuine one I get error DEV_TARGET_HELD_UNDER_RESET if I attach the reset line, and no STM target found error without it. I have the RST line on the processor pulled up with external 10k, and BOOT0 pin pulled low with 10k. I go

I am working with a NUCLEO-WB15CC, and it seems that I can't read or write anymore. When I connect via ST-Link in STM32CubeProgrammer (v2.14.0) I just get Error: Data read failed When I try to read registers, I get the same error.I also can't erase the chip: Error: Mass erase operation failed.Please verify flash protection RDP option byte is AA, so that can't be the problem.For write protection, I don't really remember what the default values was, but they are: 0xff, 0x0, 0xff, 0x0,I can still see target information in Programmer but nothing else seems to work, have I bricked the chip? Edit: I noticed I also can't read registers via the CLI, so maybe it's not a bug in STM32CubeProgrammer.This is the command I used: STM32_Programmer_CLI.exe" -c port=SWD -r32 0x08000000 0x4 Which results in Error: failed to read the requested memory content Read protection seems to be disabled:Here are all the option bytes:OPTION BYTES BANK: 0 Read Out

STM32F446, locked to RDP1, BOR set to 3 is incorrectly read out/displayed [EDIT] see next post [/EDIT] in CubeProgrammer v2.12.0:The same chip read out by STLink Utilities:Note, that the write protection is read out/displayed correctly (although very confusingly differently) in CubeProgrammer.I'd also add a recommendation/change request: similarly to STLink Utilities, read out current Option Bytes when OB are to be displayed for the first time [EDIT] this appears to be done when connection but the recommendation to add to level-1 log holds [/EDIT]  and add a line to the level-1 log that you've done so.JW

Hello all,I'd like to know if there is a set of acceptable UART baud rates for CLI use (CubeProgrammer CLI defaults to 115200 baud for UART).Looking at the GUI for CubeProgrammer, after selecting UART, it shows that a baud of 460800 or 921600 is possible, but only a baud of 460800 worked with the CLI, but 921600 timed out (I think.. the window closes very fast, as we're 'calling' the CLI from within a Python script).Any help would be appreciated. 460k baud is still much faster than the default, but if I can push the limits with 921k, I'd be happier :)Thanks!

When loading a .hex file into flash, the STM32CubeProgrammer (v 2.13.0) miscalculates which sectors to erase and as a result, the download often fails unless the region being loaded has been previously erased or happens to contain the same values.For example (see attached image), when loading an image that is 0x23B74 bytes (142.86KB) bytes to address 0x08004000 in an STM32L471 (256 x 2K sectors), it erases sectors 4..39. The start sector for address 0x08004000 should be 8 (8 x 2048 = 0x4000) and the end sector (0x08004000+0x23B74=0x08027B74) should be 0x4F (79 decimal)If I'm doing something wrong, suggestions would be appreciated!

I see a FAIL.txt file in the mass storage that says "The interface firmware FAILED to reset/halt the target MCU".LD1 and LD3 are red.I cannot even load the simple programs like Blink LED using any IDE.The on-board F401RE chip is quite hot. Dropping a bin file doesn't help either. Nothing is running on it.It was working perfectly 2 days ago and I don't know why it doesn't work anymore.Any help or suggestions will be appreciated. I included some photos for reference.P.S. I tried STMCubeProgrammer but that doesn't connect either.

Dear @KDJEM.1 when I read the manual "rm0432" It is given thatThe Flash memory programming sequence in standard mode is as follows:1. Check that no Flash main memory operation is ongoing by checking the BSY bit in theFlash status register (FLASH_SR).2. Check and clear all error programming flags due to a previous programming. If not,PGSERR is set.3. Set the PG bit in the Flash control register (FLASH_CR).4. Perform the data write operation at the desired memory address, inside main memoryblock or OTP area. Only double word can be programmed.– Write a first word in an address aligned with double word– Write the second word5. Wait until the BSY bit is cleared in the FLASH_SR register.6.

Does the STM32 ST-LINK utility work with Windows 11??

I'm new to stm32 programming, but have experience with other complex low level drivers. I'm looking for ideas because I'm confused by this issue.I hired a contractor to write code to view a few sensors, monitor a few rotary encoders, and use a 320x240 1 bit lcd using SPI (he used the lvgl library for this) since I'm not familiar with stm32.This seem to work pretty well on his system. However, when I load his hex file (or build it myself) it runs around 100x slower, and has a few other minor issues that don't seem related to performance, but maybe they are? It mostly works, like the encoders are working, sensors are giving reasonable values, but one encoder doesn't work and the fps of the screen is about 0.3 instead of 30. I've seen a video of his device and it works well.We both have multiple programmers (I'm mostly using the official st link v3), and both have multiple copies of the pcb with the stm32 chip.I did use HAL_RCC_GetSysClockFreq to check the frequency and it reports the cor
