📦 version 1.7.5, in ubuntu jammy

✨ NAME ✨

okay bestie, meet dfu-tool — the manual page for it, anyway, and it's the one that writes firmware to DFU devices. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

dfu-tool [CMD]

🦋 DESCRIPTION 🦋

so this manual page is the lil quick-and-dirty rundown of the dfu-tool command. not the whole novel, just the highlights. 🫶

dfu-tool lets you write all kinds of different firmware onto devices that support the USB Device Firmware Upgrade protocol. it's giving firmware girlie. it can also flip your device out of normal runtime mode and into DFU mode, which is the mode where you're actually allowed to read and write firmware. 🔥

and here's the fun part — you can either write the whole device in one single operation, or you can be picky and specify individual targets using their alternative name or their number. your call, main character. 👑

all the synchronous actions can be safely cancelled, no panic. and if something fails, you get errors with both a type and a full textual description — so you actually know what went wrong instead of just vibing in the dark. 😭

also, libdfu supports DFU 1.0, DFU 1.1, and the ST DfuSe vendor extension, plus it handles a whole bunch of device quirks that are, unfortunately, absolutely necessary for the real-world implementations of DFU. it's giving "we tried to make it work with everything and we mostly did." 💀

💖 OPTIONS 💖

the dfu-tool command takes various options depending on the action you're doing — it's not a one-size-fits-all situation, bestie.

  • run dfu-tool --help to get the full list. yes, literally just do that. it's right there. ✨
