THE CURSOR FOR HARDWARE.
Build, flash, and debug with an AI that reads your actual registers. Not the internet's best guess.
Proof, not promise
The same question, put to a model that can't see your board
One reasons about your firmware. The other reads it.

One IDE, three modes
Files and the editor front and center, HardwarePilot on the right. The layout the IDE opens into by default.

From source to silicon, every step stays connected.
Silicon support
4 tiers, 14 catalog profiles
Anything with a valid SVD works beyond this curated list. See the full chip support page for per-target verification status.

The view behind the paragraph
The same capture backs every answer HardwarePilot gives.
What crashed, and why?
HardFault_Handler, entered with LR 0xFFFFFFF9. The exception was returning to the main stack.
r3 holds a sentinel value, not a real address. It came from uninitialized memory or a pointer corrupted earlier.
sp and msp both land here. The stack is intact, so this is not an overflow.
It's a bad pointer, and the register dump alone is enough to say so.
What's actually behind it
The reference platform runs on real silicon
STM32F405 boots, builds, flashes, and debugs on actual hardware, plus QEMU for a no-board start. Not a demo built for a screenshot.
Answers grounded in your target
Register reads, memory dumps, and pin checks come from the project and target in front of you, not a canned answer.
Open protocols, not a black box
GDB/MI, SVD, ELF/DWARF, and RTT/SWO. The same standards you would reach for by hand in a terminal.
A real desktop app, not a browser tab
Local work stays fast, with nothing waiting on a network round trip.
Debug with what's actually on the chip.
Prescaler is opening soon. Join the list for release and testing updates.
