FPGA Management C API Examples
==============================

Overview
--------

This directory contains example code demonstrating how to use the AWS
FPGA Management C API for clearing and loading FPGA images.

Prerequisites
-------------

- AWS F2 Instance
- AWS FPGA SDK
- GCC Compiler

Setup
-----

1. Clone the repository
2. Source the SDK:

``source ./sdk_setup.sh``

Examples
--------

The repository includes the following examples:

FPGA Clearing
~~~~~~~~~~~~~

1. ``clear_single_fpga.c``: Demonstrates clearing an image from a single
   FPGA slot
2. ``clear_multiple_fpga.c``: Demonstrates clearing images from 8 FPGA
   slots

FPGA Loading
~~~~~~~~~~~~

1. ``load_single_fpga.c``: Demonstrates loading an AFI to a single FPGA
   slot
2. ``load_multiple_fpga.c``: Demonstrates loading an AFI to 8 FPGA slots
3. ``prefetch_multiple_afi.c``: Demonstrates loading multiple AFIs to a
   single FPGA slot

Building the Examples
---------------------

The examples are built while sourcing the SDK. If subsequent edits are
made, the examples can be rebuilt by navigating to the example source
directory and running:

``make``

To build a specific example:

- ``make clear_single_fpga``
- ``make clear_multiple_fpga``
- ``make load_single_fpga``
- ``make load_multiple_fpga``
- ``make prefetch_multiple_afi``

Running the Examples
--------------------

Ensure you have sourced the AWS FPGA SDK before running:

``source ./sdk_setup.sh``

Run an example:

- ``sudo ./clear_single_fpga``
- ``sudo ./clear_multiple_fpga``
- ``sudo ./load_single_fpga``
- ``sudo ./load_multiple_fpga``
- ``sudo ./prefetch_multiple_afi``

Important Notes
---------------

- These examples must be run on an F2 instance
- Ensure you have the correct AFI ID when loading images
- Always check error messages for troubleshooting
