Firmware Update

The Safety Processor is used by programming the firmware provided by Space Cubics.

The development environment includes scripts for updating the firmware of the Safety Processor. By connecting a Microchip FlashPro to the OBC and running the following commands, you can update the firmware:

Modifications to the Safety Processor logic by the user are not supported. It is recommended to always use the latest version of the firmware.

$ cd igloo2/tools
$ make program_image

After running the command, verify that the process completes successfully by confirming output similar to the following log:

$ mkdir -p ./log && echo "*" > ./log/.gitignore
