Method 2: USB Flashing via STM32CubeProgrammer (For Advanced Users)

If your board doesn’t support SD card bootloader, use the DFU (Device Firmware Upgrade) mode.

1. Install STM32CubeProgrammer.
2. Put the Sapphire Pro into DFU mode:
   • Connect USB to PC
   • Short the boot0 jumper (pins labelled BOOT0 on the board) while powering on.
3. Open STM32CubeProgrammer, select USB as connection.
4. Load your .bin or .hex firmware file.
5. Click "Download" – wait for verification.
6. Remove the boot0 jumper and reset the board.

This method is more reliable but requires steady hands and proper drivers.

2. Download Required Tools

• VS Code with PlatformIO extension (recommended for 32-bit boards)
• Arduino IDE (for 8-bit Gen L boards)
• The latest Marlin firmware source code (not just a .bin file – you often need to compile yourself for Sapphire Pro).
• Two Trees Sapphire Pro example configurations (available on the Two Trees official GitHub or community repositories like "Marlin-Config-SapphirePro").
