uspiflash apt repository

Debian packages built from mithro/uspiflash. Rolling release: every push publishes a new version.

A generator of tiny, single-file C libraries that detect SPI flash chips (JEDEC read-id, legacy ids, SFDP) and report their size, geometry, voltages, capabilities and supported commands, built from the spiflash database. Two packages:

python3-uspiflash provides the uspiflash command. It is architecture all (pure Python), so it installs on any Debian or Raspberry Pi OS machine; it depends on python3-spiflash from spiflash's own apt repository.
uspiflash-linux identifies the SPI flash chip on a Linux spidev device (/dev/spidevX.Y) and describes it as spiflash id does. It is a small C program with no dependency beyond libc, built for amd64, i386, arm64, armhf and riscv64 (riscv64 from trixie on).

Signing key fingerprint: 2E195D58706D44E85704156604FAD17C2A3B8344

Signed with the repository's own key. apt reads a keyring's format from its file extension, so the key is published in both encodings: uspiflash.gpg is the binary keyring and uspiflash.asc the ASCII-armoured one. The commands above use the binary form. To use the armoured key instead, download uspiflash.asc and give signed-by= a path ending in .asc to match — apt ignores a keyring whose extension disagrees with its contents.

Each suite is a separate flat repository, so the same version can ship for several Debian releases.
