💖 st-util — the STM32 GDB server bestie 💖

okay so real quick, this is st-util from the stlink manual (section 1), and bestie, if you're out here trying to talk to an STM32 chip, this is literally your girl. no cap. 🦋

✨ NAME ✨

st-util — run a GDB server so you can vibe (technically: interact) with an STM32 device. 🔥

🌸 SYNOPSIS 🌸

st-util [<ARGS>...]

💅 DESCRIPTION 💅

So basically you're starting up a GDB server to hang out with an STM32 device. Under the hood it runs the main binary of the local package, which lives at src/main.rs. (yes bestie, Rust. iconic behavior. 🦀)

If you don't tell it which port to use with the –listen_port option, it's gonna default to port 4242 — that's just the vibe it defaults to, periodt.

And Stlink version 2 is what you get by default, unless you specifically pass the –stlinkv1 option. that's it, that's the deal. 💫

🎀 OPTIONS 🎀

  • -h, --help — prints this message. the classic. the beloved. your bestie when you forget everything. 🫶
  • --version — prints version information. ✨
  • -v XX, --verbose=XX — pick a specific verbosity level, from 0 all the way up to 99. yeah, ninety-nine. go off. 📢
  • -v, --verbose — just generally verbose logging, no specific number needed. she'll be chatty. 💬
  • -s X, --stlink_version=X — choose which version of stlink to use. defaults to 2. 👑
  • -1, --stlinkv1 — force stlink version 1. old school, respect. 💀
  • -p 4242, --listen_port=1234 — set the gdb server listen port. default port: 4242. 🌈
  • -m, --multi — puts the gdb server into extended mode, and st-util will keep listening for connections even after you disconnect. she's not going anywhere. 💖
  • -n, --no-reset — do not reset the board on connection. 🚫
  • --semihosting — enable ARM Semihosting output on stdout. ✨

🧚 EXAMPLES 🧚

Run the GDB server on port 4500 and connect to it:

$ st-util -p 4500
$ gdb
(gdb) target extended-remote localhost:4500

see? three lines. ate. 🔥
