We are pleased to announce that STM32CubeProgrammer 2.22 is available What is new in 2.22: Support for the STM32U3 microcontrollers with 2 Mbytes of flash memory: Internal memory programming through debug and bootloader interfacesOption bytes program...
Dear STM32CubeProgrammer Community, I hope you are all doing well. Over the past months, you may have received an email from me, either through the STM32CubeProgrammer survey or on other topics like CSAT or Raspberry Pi support. First, I would like...
Major change in SigningTool for STM32N6 in STM32CubeProgrammer v2.21.0 This release, we decided to change signing tool behavior to not automatically align the payload to 0x400 with padding bytes, since this is not necessary for other STM32 series. T...
Hi,I'm looking for an STM32 flashing tool that runs on ARM Linux for use on an embedded board. In our setup, I have a processor and an STM32G491RET microcontroller connected via I2C. Now I need a command-line tool that can run on the processor to fla...
Hi,I am trying to program an SFI on a board with an STM32U535 microcontroller and I get the error message 55555. I am connected through an STLINK V3 and use STM32CubeProgrammer.The process fails even though the license counter on the HSM is decrement...
Hello, I am currently programming on an STM32WB5MMG microcontroller using Zephyr, and I'm facing an issue with flashing the coprocessor. I am using STM32CubeProgrammer to flash the firmware stm32wb5x_BLE_HCILayer_extended_fw.bin. However, after flash...
Hello.Regarding STM32CubeProgrammer CLI, I'm wondering if it is possible to reset an STM32 target only driving (high->low->high) its physical reset pin (NRST of ST-Link V2 connector) and without establishing a logical SWD/JTAG connection with it. Of ...
Hello everyone,I am trying to program an STM32L031F6P6 microcontroller, which is soldered on an adapter and connected to a breadboard.I am using an ST-LINK programmer, and I will attach a picture of the exact ST-LINK I am using. When I connect the ST...
Hello,I am currently working on a project involving the STM32L031F6P6 microcontroller, and I would like to ask a few technical questions:What are the basic settings required to initialize and get this microcontroller up and running?How can I properly...
My company wishes to implement a feature in an existing C# application in order to download firmware to MCUs (USB DFU only).I was able to get this done using the drivers and dlls provided through Dfuse (https://www.st.com/en/development-tools/stsw-st...
Hello,There seems to be a bug in Stm32CubeProgrammer v2.19.0I connect the STM32F767 with USB1 (DFU).When I press the CONNECT button, the connection stops at 44 bytes.the connection is "Not connected"however, I can now download a program.
If I try to write data to high-cycle flash from command line with the -w16 command when trust zone is activated it says that it succeeded but the data isn't written.Using -w16 without trust zone works as expected.Writing data with --download from com...
