It is used to load gateware over USB onto Cynthion's FPGA. Alternatively it may be used as an on-board or external debugger for certain other FPGA platforms.\n\nApollo consists of two main parts: firmware for the on-board debug microcontroller and Python-based software for the host computer.\n\n## Installing Host Software\n\nIf you have a Cynthion, Apollo host software is installed automatically as a dependency when you [install Cynthion software](https://cynthion.readthedocs.io/en/latest/getting_started.html#cynthion-host-software-installation).\n\nTo explicitly install the apollo-fpga Python module and the `apollo` command-line tool or to upgrade them to the latest version run:\n```\npip install --upgrade apollo-fpga\n```\n\n## Building and Installing Firmware\n\nTo upgrade Apollo firmware on a Cynthion it is typically not necessary to compile the firmware yourself. Instead follow [Upgrading Cynthion Device Firmware](https://cynthion.readthedocs.io/en/latest/getting_started.html#updating-cynthion-microcontroller-firmware-and-fpga-configuration-flash).\n\nTo compile and install onto Cynthion run:\n\n```\n$ cd apollo/firmware\n$ make APOLLO_BOARD=cynthion get-deps dfu\n```\n\nThis will download dependencies, compile the firmware, and install it onto Cynthion with [pyfwup](https://github.com/greatscottgadgets/pyfwup) and [Saturn-V](https://github.com/greatscottgadgets/saturn-v).\n\nAlternatively you can use variables to specify a different board or a fixed hardware revision:\n\n```\n$ cd apollo/firmware\n$ make APOLLO_BOARD=cynthion BOARD_REVISION_MAJOR=1 BOARD_REVISION_MINOR=4 get-deps dfu\n```\n\nA specified revision will override automatic hardware revision detection which is supported on Cynthion r0.6 and above. You must specify the revision to compile firmware for a Cynthion older than r0.6.\n\nOnce installation is complete, LED A should activate, indicating that Apollo is running.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgreatscottgadgets%2Fapollo","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgreatscottgadgets%2Fapollo","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgreatscottgadgets%2Fapollo/lists"}
