ISP mode download
Method 1: Under power on state, press and hold B00T0 key and reset key, then release reset
key, and release B00T0 key 0.5 seconds later
Method 2: In the power off state, press and hold the BOOTO key, and release the BOOTO 0.5s after power on
USB data cable is connected to MCU TYPE-C interface, serial port is connected to PA9 and PA10, STM32CubeProg is recommended for downloading software, We Act Studio Down load Tool
Serial port download
USB to serial port (ex.: CH340) TX - PA10, RX - PA9. At the same time, do not connect the Type-C of MCU to the computer. You must use external power supply, or the MCU download will be affected
Use STM32CubeProgrammer for serial port download
USB download (DFU download)
STM32CubeProgrammer Ticks the USB mode, WeAct Studio Download Tool Double click WeAct Studio USB Download Tool.bat, and then operate according to the prompts
MCU enters ISP mode, uses USB data cable to connect computer to select firmware, and other operations are consistent with serial port downloading
STM32 Bootloader or DFU in FS Mode device appears in Device Manager ->Universal Serial Bus device
If the device appears as STM Device in DFU Mode, you need to right-click to uninstall the device and check to delete the driver software of the Device before installing it
WeAct Studio Download Tool/DFU_ Driver/Driver/directory, select STM32Bootloader.inf, and right-click to install
The USB download may be unstable due to the weather. If the following ERROR occurs repeatedly or the device cannot be recognized, please use the serial port to download and disconnect the USB connection.
1 2 Error: failed to download Segment[0] Error: failed to download the File
The reason for the above ERROR: the room temperature is low, and the HSI has a deviation. The USB download uses an external high-speed crystal oscillator, while the ISP program (ST bootstrap program) measures the external crystal oscillator HSE frequency through the HSI and then configures the clock. When the HSI deviation is too large, the HSE measurement frequency is incorrect, resulting in incorrect USB timing and download errors. For details, see the network disk/general document/AN2606 STM32 microcontroller system memory bootstrap mode Solution to pdf: Heat the MCU properly to above 25 ° C (cover the heat with hands)
ST Link/J-Iink Download
SW interface connecting STM32: SW interface GND SCK DIO 3.3V
Click the download button in MDK software or select ST Link in STM32CubeProg to operate according to the prompts.
For the CubeMX project or the standard library project, the SW debugging interface should be enabled, otherwise the debugger cannot recognize the MCU
The debugger cannot recognize MCU due to incorrect setting of code engineering crystal oscillator or other abnormalities. At this time, manually set MCU to enter ISP mode, and the debugger can identify MCU, and then click Download
ISP mode is just a section of startup code solidified in MCU by ST company. Check BOOTx settings. In operation mode, the system will run to the address 0x08000000, and in download mode, it will wait for download command. At this time, the SW debugging download interface is open, and the debugger can read and download MCU code.

Some JLinks of VTEST pin 1 need to receive 3.3V to identify MCU 3.3V 3.3V GND

Debugging interface includes SW interface and JTAG interface. ARM debugger basically supports SW interface
JLink can be connected to the chip, but it cannot be downloaded. Please upgrade the JLink driver to the latest version. The V6.50a test is available
