First board lands. wadamesh builds the LVGL touch firmware as its own project, consuming the MeshCore core via lib_deps @ git tag (ALLFATHER-BV/MeshCore #v1.16.0-wada.0) — no vendored core in this repo. Output is byte-identical to the in-tree meshcomod build (delta = embedded build-path strings only). Contents: companion_radio app (MyMesh/main/DataStore), ui-touch LVGL UI, variants/heltec_v4 board glue, boards/heltec_v4.json, lv_conf, the bundled ed25519 lib, AsyncElegantOTA, partition table, and a flattened platformio.ini for env heltec_v4_tft_companion_radio_usb_tcp_touch. MeshCore-derived files (app glue) remain MIT; ui-touch is GPL — see NOTICE. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Signed-off-by: Kaj Schittecat <kaj@schittecat.com>

# Heltec V4 TFT touch firmware — custom partition table.
|
||
#
|
||
# 16 MB layout with TWO EQUAL OTA app slots so the touch firmware can
|
||
# self-update (HTTP OTA via the meshcomod proxy). The app region (app0+app1)
|
||
# is split evenly at 3.875 MB each — the firmware is ~2.4–2.5 MB, leaving
|
||
# ~1.3 MB of growth headroom per slot. The tiles + spiffs offsets are UNCHANGED,
|
||
# so an OTA (or the one-time USB re-flash that installs this table) keeps the
|
||
# map tile cache and all user data (/new_prefs, /contacts3, /channels2, chat
|
||
# history) intact.
|
||
# - app0 3.875 MB (ota_0) ┐ equal A/B slots; OTA ping-pongs between them
|
||
# - app1 3.875 MB (ota_1) ┘ (was 1.5 MB — too small to hold the image)
|
||
# - "tiles" 4.75 MB (subtype 0x83 = LittleFS) for the map tab's tile pack
|
||
# - spiffs 3.375 MB for user data
|
||
#
|
||
# Layout (16 MB total):
|
||
# 0x000000–0x009000 bootloader + partition table
|
||
# 0x009000–0x00E000 nvs (20 KB, unchanged)
|
||
# 0x00E000–0x010000 otadata (8 KB, unchanged)
|
||
# 0x010000–0x3F0000 app0 (3.875 MB, ota_0)
|
||
# 0x3F0000–0x7D0000 app1 (3.875 MB, ota_1 — grown from 1.5 MB)
|
||
# 0x7D0000–0xC90000 tiles (4.75 MB, LittleFS, type 0x83) [unchanged]
|
||
# 0xC90000–0xFF0000 spiffs (3.375 MB) [unchanged]
|
||
# 0xFF0000–0x1000000 coredump (64 KB, unchanged)
|
||
#
|
||
# Subtype 0x83 = ESP-IDF LittleFS subtype. The Arduino LittleFSFS instance
|
||
# in UITask.cpp mounts this by partition label "tiles". SPIFFS.begin()
|
||
# matches the first partition with subtype `spiffs` (== our "spiffs"
|
||
# partition), so the two filesystems don't collide.
