System Flashing and Initialization

Hardware Connections​

Prerequisites​

  • NE301 main board Γ— 1
  • ST-Link V2 Γ— 1
  • 4-pin 1.25 mm JST (male) β†’ 2.54 mm Dupont (female) cable for STM32N6 flashing
  • 3-pin 2.54 mm Dupont (female-female) cable for STM32U0 flashing
  • USB Type-C cable compatible with your PC port (Type-A host requires a Cβ†’A cable)

The mainboard contains two MCUs： stm32n6 and stm32u0

Ready for Flashing apps, web, or models to stm32n6​

  1. Toggle DIP switch #2 to ON to enter flashing mode. After flashing, switch it back and power-cycle (or press Reset) to boot into runtime mode.

  3. Connect the board to the PC or a power adapter via USB Type-C.

    The on-board DEBUG LED stays solid to indicate flashing mode.

Ready for Flashing wakecore to stm32u0​

  1. Use the 3-pin Dupont cable to connect the ST-Link directly to the STM32U0 header, then attach ST-Link to the PC.
