Flash the C2401

We recommend flashing from Linux or a Linux VM. See Install a VMware VM for instructions on installing the VM and SDK Manager.

1. Flash with NVIDIA SDK Manager

1.1 Configure the VMware USB Mode

Set the USB connection mode to "Connect the device to the foreground virtual machine" to prevent the flash from failing when the board reboots during the process.

1.2 Enter Recovery Mode

The C2401 provides two ways to enter recovery mode:

Method 1 (button): With the power disconnected, press and hold the REC button, then connect power.

Method 2 (DIP switch): Set DIP switch 3 on the back of the carrier board to ON. The system will enter recovery mode automatically each time it powers on.

Recovery mode lasts for only 60 seconds. If no flashing operation is detected, the system automatically continues with the normal boot sequence.

1.3 Configure the SDK

• Uncheck Host Machine, then click CONTINUE
• Select only Jetson Linux

1.4 Wait for the Download to Complete

1.5 Configure the Flash Parameters

• Pre-Config: Set the username and password in advance
• Runtime: Configure the username and password after first boot
• Storage Device: Select the target medium (SSD)
• Select Developer Kit Version

Wait patiently for the flash to finish; it takes about 10–20 minutes. The board may reconnect to the host several times. Do not disconnect the data cable or power off the board.

After flashing, power on the board. The flash was successful if it boots into the desktop or initial setup screen.

2. Flash SUPER Firmware from the Command Line

This operation requires the official firmware environment. First complete at least one full flash with SDK Manager to create the firmware cache.

2.1 Enter Recovery Mode

Press and hold the REC button, connect the board to the computer with a Type-C data cable, and connect board power to enter recovery mode.

2.2 Flash with the Official Firmware

Close SDK Manager before proceeding. Flashing takes about 10–20 minutes.

Command for JetPack 6/7:

The command parameters are identical; only the firmware directory differs. Use JetPack_6.2.1_Linux_... for JetPack 6.2.1 and JetPack_7.2_Linux_... for JetPack 7.2. The following example uses JetPack 7.2.

cd /home/ubuntu/nvidia/nvidia_sdk/JetPack_7.2_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
  -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit-super internal

Command for JetPack 5.1.5:

cd /home/ubuntu/nvidia/nvidia_sdk/JetPack_5.1.5_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 \
  -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" \
  --showlogs --network usb0 jetson-orin-nano-devkit-super internal

2.3 Verify SUPER Mode

After powering on the board and completing user setup, select a power mode from the upper-right corner of the desktop. 25W & MAXN SUPER is available only in SUPER mode; standard mode provides only 7W and 15W.

If 25W and MAXN SUPER appear in the power-mode list, the SUPER firmware is active. If only 7W and 15W are available, confirm that the flash command uses the jetson-orin-nano-devkit-super configuration, perform a complete reflash, and check again after rebooting.

3. Back Up and Restore Existing Firmware

3.1 Back Up the Firmware

Press and hold the REC button, connect the board to the computer over Type-C, and connect power to enter recovery mode.

Alternatively, while the board is running normally and connected to the host, run:

sudo reboot -f forced-recovery

Enter the command-line directory in the firmware cache used for the original flash:

cd /home/ubuntu/nvidia/nvidia_sdk/JetPack_7.2_Linux_JETSON_ORIN_NANO_TARGETS/Linux_for_Tegra

Install the dependencies:

sudo apt-get install qemu-user-static libxml2-utils abootimg sshpass nfs-kernel-server binutils

Backup command:

sudo ./tools/backup_restore/l4t_backup_restore.sh -b -e nvme0n1 jetson-orin-nano-devkit-nvme

Restore command:

sudo ./tools/backup_restore/l4t_backup_restore.sh -r -e nvme0n1 jetson-orin-nano-devkit-nvme

When restoring a backup on a third-party carrier board, edit nvrestore_partitions.sh and comment out lines 292–296.
