Emergency Download Mode (EDL)
Rhino Pi A1 provides two pin test points for entering EDL mode. EDL is Qualcomm's emergency download mode used for recovery and firmware flashing.
Usage Guide
- Short the FORCE_USB_BOOT and VREG_L15 test points with a Dupont wire.
- Insert DC power.
- Remove the Dupont wire.
If done correctly, the board should enter EDL mode. Then connect a USB Type-C cable to flash firmware.
