Board Introduction
The debug baseboard (model: A8625MY1-SUB-REVA) is a companion development baseboard designed specifically for the A8625MY1 AI compute card. It breaks out all Mini PCIe edge-connector interfaces into standardized debug interfaces and provides a complete power solution, making it suitable for rapid prototyping and function validation.

DIP Switch Description
A DIP switch (or FORCE_USB_BOOT jumper cap) is provided on the baseboard for entering flashing mode:
| Position | State | Function |
|---|---|---|
| Normal position | Default | Normal boot and run |
| Force download position | Connected to 1.8V | Enter EDL (9008) flashing mode |
Note
Power off the device before operating the DIP switch to avoid hot-plug damage.
