Using the BMC#

The Baseboard Management Controller (BMC) provides remote management capabilities. You can perform monitoring and management tasks securely and out of band. These include controlling system power, updating firmware, and gathering telemetry. For details about using the BMC, see IGX BMC User Guide.

Put the system into recovery mode#

Putting the system into recovery mode is only necessary when you re-flashing the system.

  1. Access the BMC by using SSH. For details, see BMC Quickstart.

  2. Put the IGX Developer Kit into recovery mode by powerctrl recovery.

    1root@mgx-3809:~# powerctrl recovery
2Host Power Control
3Host Recovery…
4Resetting Host…
5root@mgx-3809:~#

    Note

    The powerctrl recovery command works when Tegra is on. The poweron logic in SMCU has an internal wait time of 20 seconds to allow the VRS12 rails to stabilize. Please wait for 20 seconds after poweron before trying to use the powerctrl recovery command.

  3. Confirm the IGX Developer Kit is in recovery mode by running lsusb on the re-flash host:

    lsusb | grep NVIDIA

    The output should be:

    Bus 003 Device 003: ID 0955:7023 NVIDIA Corp. APX
