Update Your BMC Firmware

Use the following command-line instructions to update the BMC firmware on your NVIDIA IGX Developer Kit or your NVIDIA IGX Orin Board Kit. However, we recommend that you update your BMC firmware by using the BMC web user interface.

Use this documentation to perform the following tasks:

• Get the BMC firmware

• Choose the correct firmware update procedure

• Update your IGX Developer Kit BMC(Non-ERoT) Firmware

• Update your IGX Orin Board Kit BMC(ERoT) Firmware

1. Download bmc_fw_R36.x.x_aarch64.tbz2 to your Linux host computer from the IGX Download Center.

2. On your host computer, extract the downloaded BMC firmware using command line, for example

   Copy

   Copied!

               
   
               
   tar -xvjf bmc_fw_R36.x.x_aarch64.tbz2
           

   Firmware images are available in bmc/fw/apfw directory.

   Note

   Check bmc/README for information about release versions and dates.

External Root of Trust (ERoT) hardware is part of the BMC module for the IGX Orin Board Kit, which is intended for production. ERoT hardware provides a secure flash and boot mechanism. Because the IGX Developer Kit is not intended for production, it is provided without ERoT hardware.

Choose the correct update instructions to avoid damaging your hardware:

• IGX Developer Kit — Use the Non-ERoT firmware update instructions.

• IGX Orin Board Kit — Use the ERoT firmware update instructions.

Use one of the following procedures to update your IGX Developer Kit (Non-ERoT). Do the steps on the local Ubuntu host computer that has the BMC is attached.

Recommended procedure

1. Run the following code.

   sudo apt-get install sshpass
           

Alternative procedure

1. Verify that you are using the IGX Developer Kit.

   Warning

   If you use this procedure with the IGX Orin Board Kit, you will put your BMC into a nonrecoverable state.

2. Comment out everything inside /usr/share/mctp/mctp by prepending each line with a #, using a text editor such as vi, or with the following sed command.

   reboot
           

7. Set the password again, as this procedure reset it to the default 0penBmc.

Use the following procedure to update the IGX Orin Board Kit (ERoT). Do the steps on the local Ubuntu host computer that has the BMC is attached.

1. Verify that you are using the IGX Orin Board Kit, not the IGX Developer Kit.

   Warning

   If you use this procedure with the IGX Developer Kit, you will put your BMC into a nonrecoverable state.

2. Download igx-bmc-apfw-erot.fwpkg from the path in Steps to Get BMC Firmware.

3. Save the IP address of your BMC as an environment variable by running the following code. Replace <BMC_IP> with your IP address, for example 192.168.1.110.

                      -d '{"username": "root", "password": "<BMC_Password>"}' | grep token | awk '{print $2;}' | tr -d '"'`
           

5. To start the update, run the following command. You save the task id as an environment variable so that you can check the status of the update in the following step.
