Flash & Partitions
Device is running the app.
Read Partition Table / Erase / Flash work only from the bootloader. Restart the chip into bootloader (download) mode to continue.
Terminal
Attaches straight to the serial console of the firmware that is already running — the chip is
not reset and does not enter the bootloader. Use Device Connection for chip
info, and Flash & Partitions for erase / partition-table / flash, which require the bootloader.
Upload core dump
Decoding runs entirely in this browser — a Web Worker boots Pyodide
(CPython in WASM) and symbolises with DWARF + CFI. No host gdb/addr2line,
no upload to a server. Two drop areas: the core dump, and optionally the
matching firmware .elf (needed only if the server can't serve
it — e.g. when these files are hosted as static content).
Choose a core dump (.bin / .b64 / .elf) or drop here
(optional) matching firmware .elf for symbolication — or drop it here
