💖 fwexec — the manual page, but make it cute 💖

okay bestie, so this is fwexec(1), and it lives in the General Commands Manual section of your local man pages. pull up a chair, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

fwexec — upload a firmware image to a connected NXT device and run it straight from RAM 💅

🌸 SYNOPSIS 🌸

fwexec [options]... file [load_address [jump_address]]
fwexec (-l|-h)

like. that's it. that's the whole vibe. two shapes: one for actually doing the thing, one for just peeking around 👑

🦋 DESCRIPTION 🦋

so fwexec is basically the sibling of fwflash(1), right? same energy, but here's the plot twist: the firmware image gets uploaded to NXT RAM and executed from there, not flashed to memory. RAM. in the moment. main character energy only, no permanent commitment ✨

bestie, important: the image must have been compiled specially to handle this. don't just throw any old firmware at it, she won't survive 😭

your NXT has to be in bootloader mode</> — head over to fwflash(1) for the details on how to get there, iykyk.

and fun fact: fwexec is part of LibNXT. we're all in the same friend group 💖

👑 OPTIONS 👑

  • -l — list all the detected devices and dip. that's it, that's the whole job 💅
  • -y — let it reset into bootloader mode without asking you first. ⚠️ heads up bestie: this erases the NXT memory. no takebacks. make sure you actually mean it 😭
  • -h — show the help message and exit. classic, we love a helper 🫶
  • -b — only pick a device that's already in bootloader mode. ignore every other NXT hanging around. picky queen behavior and honestly? valid.
  • -s SERIAL — select the device with this serial, like 00:16:53:01:02:03. ngl this one doesn't work in bootloader mode — devices in bootloader mode always get selected regardless. fr fr.
  • -n NAME — select the device with this name, like NXT. same deal as -s: it does not work in bootloader mode, since devices in bootloader mode are always selected. periodt.
