Jetson Module Adaptation and Bring-Up: Checklists

This topic presents several checklists of steps in bringing up a custom carrier board with an NVIDIA® Jetson™ SOM. It presents one group of checklists for hardware, and another for software.

The right-hand columns indicate which bring-up steps apply to which processors. An ‘O’ in a given processor’s column indicates a step that applies to that processor; a dash indicates a step that does not.

NVIDIA recommends that you print this topic and use it as an actual checklist. As you complete each applicable step for your processor, check off the corresponding ‘O’. In this way you can ensure that you do not miss or repeat any steps.

Hardware Bring-Up Checklist

This section provides a checklist for the platform hardware bring-up process.

Note

The “Adaptation and Bring-Up” topics for some platforms contain a section that you should read before you begin the bring-up process. Such sections have headings like “Bring-Up Considerations,” and generally appear near the end of the topic. Check for such a section in your platform’s topic before you start bring-up.
