Flash the C1901 ​

This guide explains how to flash the system onto the C1901 carrier board. C1901 is developed from the reference design, so the flashing process is essentially the same as the official Developer Kit.

Before You Start

  • Ubuntu VM and SDK Manager installed (see the installation guide)
  • A USB Type-C cable capable of data transfer
  • C1901 carrier board + Jetson Orin Nano/NX module

1. Enter Recovery Mode ​

The C1901 enters recovery mode through the 12-pin debug header.

Steps:

  1. Disconnect the C1901 power.
  2. Use a jumper cap to short the FC REC and GND pins.
  3. Connect the power.
  4. Connect the C1901 to the VM with a USB Type-C cable.
  5. Remove the jumper cap.

2. Detect the Device ​

Run in the Ubuntu terminal:

bash
lsusb | grep -i nvidia

C1901 Detect Device

If an NVIDIA device is detected, recovery mode was entered successfully.

3. Flash with SDK Manager ​

Open SDK Manager and select the corresponding module model (Orin Nano or Orin NX).

C1901 Select Hardware

Note

For the C1901, select the model that matches your module. Do not choose custom options other than the Developer Kit version.

Uncheck Host Machine and keep only Target Hardware.
