Setup

Using SEP with BaseOS only:

1. Download the L4T_RELEASE_PACKAGE (Jetson_Linux_R36.2.0_aarch64.tbz2), and all Safety Extension Packages (SEPs).

2. Download the SAMPLE_FS_PACKAGE (Tegra_Linux_Sample-Root-Filesystem_R36.2.0_aarch64.tbz2) from the Jetson downloads page.

3. Untar the packages:

   $ tar xf ${L4T_RELEASE_PACKAGE}
   $ sudo tar xpf ${SAMPLE_FS_PACKAGE} -C Linux_for_Tegra/rootfs/
   $ sudo tar xvjf host_overlay_sep_orin_partner.tbz2
   $ sudo tar xvjf sep_orin_partner.tbz2 -C Linux_for_Tegra/rootfs/
   $ cd Linux_for_Tegra/
   $ sudo ./apply_binaries.sh
   $ sudo ./tools/l4t_flash_prerequisites.sh
           

   
   

4. Flash the NVIDIA IGX Orin Developer Kit safety configuration:

   sudo ./flash.sh p3740-0002+p3701-0008-safety internal
           

   
   

5. After flashing with the step above, proceed to the IGX BaseOS Quick Start Guide: Installing the IGX BaseOS Image for BaseOS installations.

   Note

   Please do not flash QSPI again.

   
   

6. Once BaseOS is installed to NVME, run the following:

   Copy

   scp sep_orin_partner.tbz2 <username>@<IGX-IP>:/tmp
           

   
   

7. Follow the below steps/commands on the IGX device as root:

   sudo -s
   cp /tmp/sep_orin_partner.tbz2 /
   cd /
   tar -xvf sep_orin_partner.tbz2
   systemctl reboot
           

   
   

8. Once the Tegra flashing is complete, do a power-cycle from either BMC or SMCU.

   1. From BMC:

      powerctl power_cycle
              

      
      

   2. From SMCU:

      Copy

      Copied!

                  
      
                  
      aurixreset
      poweron
              

      
      

IGX BMC can flash the MCU Firmware and upgrade the MCU. To flash MCU, you need to follow below steps,

1. To determine your board, log in to BMC and run the following:

   Copy

   Copied!

               
   
               
   i2cdump -f -y 10 0x50
           

   Note

   Look for either the QS2 or TS3 string to determine your board type.

   
   

2. The SMCU firmware files are placed under Linux_for_Tegra/smcu/. These are L4T-P3740-AFW-Aurix-StepB.hex for QS2(C01) and L4T-P3740-C00-AFW-Aurix-StepB.hex for TS3(C00).

3. Copy the firmware file to the BMC rootfs before flashing.

4. Log in to BMC as mentioned in the BMC User Guide.

5. Go to the mcu-flash directory.

   root@mgx-3809:~# cd /etc/smcu-flash
           

   
   

6. Copy the MCU firmware file from the package to BMC using scp.

7. Stop the console service.

   root@mgx-3809:~# systemctl stop obmc-console\\@ttyS2.service
           

   
   

8. Flash MCU firmware and provide the MCU firmware file path.

   ./flash_tc39x.py <serial port> 921600 <FW File>
           

   Example:

   ./P3740_TC39x_Aurix.hex
           

   
   

9. Start the console service when you have finished mcu-flash.

    root@mgx-3809:~# cd /etc/smcu-flash
    root@mgx-3809:/etc/smcu-flash# ./smcu-flash.sh smcu_reset
