Firmware for the card10 badge for the Chaos Communication Camp 2019.
We keep documentation in the Documentation/ subdirectory. You can find a
rendered version over at https://firmware.card10.badge.events.ccc.de/.
If you want to help us ensure the card10 will have been exactly as we reconstructed from the audio-logs we recovered, please head over to our wiki, or directly to the issue tracker.
A full guide for building is available in the docs as How To Build.
Last Artifacts from Gitlab-CI:
Flasing with or without a debugger is described in detail in How To Flash.
If you have a debugger, head over to our Debugger page to learn how to use it.

Learn more about card10's Serial Console.
The bootloader is used to flash card10 without an external debugger. It exposes the file system via USB and accepts a card10.bin file as firmware image.
To flash the bootloader, go to the bootloader directory and follow the steps above.
To execute the bootloader, turn off card10, press the lower right button and turn on. Connect card10 via a USB cable to a computer and mount the file system. You can now copy your card10.bin file to the file system. Eject the drive (IMPORTANT!) via your operating system (umount and sync is not enough). Turn card10 off and back on again. It will try to boot the image.
IMPORTANT: The prototypes have the USB data lines reversed. Use the provided USB adapter to connect card10.
Run ./build_image. TODO: Add to meson
The tool uses Python to generate a CRC. Make sure to have python-crc16 installed.
