The merged binary (1,257,328 bytes) was below the 1.5MB size threshold,
causing it to be misidentified as app-only and flashed at 0x10000 instead
of 0x0. This corrupted the flash layout and bricked the device.
Now checks for ESP32 bootloader magic byte (0xE9) at offset 0 to reliably
distinguish merged binaries from app-only binaries, regardless of size.
Bundled esptool.py runs via sys.executable, which may be a Python
that lacks pyserial (e.g. miniconda). Reorder find_esptool() to
prefer pip-installed esptool first (handles its own deps), and
only fall back to bundled/PlatformIO scripts if pyserial is
importable. Give a clear error message if neither works.
- flash.py: standalone flash utility with serial port listing, merge-bin,
GitHub Releases download, and esptool flash support
- Display.h: hide LAN row when Local TCP disabled, show local TCP port
instead of backbone port
- README.md: comprehensive documentation — Quick Start with 3 flash options,
OLED display layout, interface modes, routing customizations, path table
fix, interface name uniqueness, hardware rationale (PSRAM/flash)
- Release/boot_app0.bin: bundled for flash.py standalone use
- .gitignore: exclude merged firmware binary build artifact
- Fix path table insert bug: C++ map::insert() silently fails when key
exists (unlike Python dict[key]=value). Changed to erase()+insert() so
updated paths (e.g. local TCP replacing stale LoRa) actually take effect.
- Add name parameter to TcpInterface constructor to give each instance a
unique identity hash, fixing map collision between backbone and local
TCP server interfaces.
- Set TCP interface bitrate to 10 Mbps (was 500 bps) so Transport
correctly prefers TCP paths over LoRa when both exist.
- Add PRG button hold >5s white screen indicator for config portal.
- Boundary mode cull_path_table: evict backbone paths first, preserving
local paths needed for inbound routing.
Bridges LoRa mesh and TCP/WiFi backbone networks using microReticulum.
Based on microReticulum_Firmware with boundary mode additions:
- BoundaryMode.h: State management and EEPROM persistence
- BoundaryConfig.h: WiFi captive portal for configuration
- TcpInterface.h: TCP backbone interface with HDLC framing
- Display.h: Custom OLED layout with network status indicators
- Transport/Identity library patches for embedded memory constraints
