CatCard v7.0.0-alpha5
CatCard v7.0.0-alpha5 -- clean-room firmware for Coldcard hardware.
Signed with the published developer key. The device shows a red genuine
light and a warning screen before it boots this; that is expected. The images
carry no bench features: no USB debug monitor and no USB key injection.
Untested on hardware unless the notes below say otherwise.
| Board | Images |
|---|---|
| mk3 | catcard-mk3-*.dfu |
| mk4, mk5 | catcard-mk4-mk5-*.dfu (one image, accepted by both) |
| Q1 | catcard-q1-*.dfu |
Each board has four images. Without -bitcoin in the name it holds every
chain CatCard knows; with it, Bitcoin alone. With -games it also carries the
games; without, it does not. Nothing else differs between the four.
Header version 7.0.0a5; built with
SOURCE_DATE_EPOCH=1791184637 (the tagged commit's time),
so rebuilding this tag reproduces the digests in SHA256SUMS and in each
build's log.
