ST-LINK V2-1

I couldn’t bear the fact that the ST-Link-V2 I had only had a USBA male connector and needed a long Dupont cable to connect to the board, so I came up with this project.

I referred to the tutorial from the guy below, thank you very much. However, I have to complain that the resistor and capacitor packages are exactly the same (I’m too lazy to change them and just use them).

I changed the schematic diagram and redrawn the PCB. The other downloading methods are exactly the same.

1. Update firmware

• Download the official firmware upgrade app

• Use the upgrade tool provided by STM32CubeProg or STM32 ST-LINK utility to upgrade

• Use the built-in upgrade tool of Keil MDK-ARM to upgrade. When the ST-link version is lower than the built-in version of MDK, you will be prompted to upgrade.

2. Verification

Display the above information and confirm that the firmware is OK

 

3. Test

1. Test the burning function, use Keil-MDK, download the program successfully, indicating that the burning function is normal
2. Test the Debug function and use Keil-MDK for debugging. If it can be debugged, it means that the Debug function is normal.
3. To test the U disk drag and burn function, you need to generate a bin file ( bin file generation method ), drag the bin file to the U disk simulated by ST-link, and successfully burn it, indicating that the virtual U disk function is normal.
4. Test the serial port transceiver function: Use Dupont cable to connect the TX and RX of ST-LINK V2-1, open the serial port assistant, send data, and the receiving area receives the same data, indicating that the serial port transceiver is normal
