Flashing the dGPU with ARM VBIOS

Download VBIOS updating tool to your IGX Developer Kit from https://developer.nvidia.com/igx-downloads.

You will need to disable the desktop when flashing ARM dGPU VBIOS

1. You may ssh into the IGX Developer Kit, or

2. Access the command line using the SOC’s UART via BMC.

From SSH or UART, kill the desktop and unload the display drivers.

            

            
$ sudo systemctl isolate multi-user
$ sudo rmmod nvidia_vrs_pseq nvidia_uvm nvidia-drm nvidia_modeset nvidia
        

Flash the VBIOS.

            

            
$ sudo ./igx_a6000_firmware_94025C000E_update
        

The system will automatically reboot upon completion

On succesful update, check VBIOS version

            

            
$ nvidia-smi -q | grep VBIOS
VBIOS Version                         : 94.02.5C.00.0E
