None of the three fixed the flash, and each carried a cost: - prefs-on-SD (1bc0c7a) also moved main.cpp onto a different set of headers than it had been compiling against. SdNvsPrefs.h's own comment warns that exact mismatch previously caused a free()-of-garbage bootloop, and a map tile regression showed up on these builds. Not worth the risk for no benefit. - LVGL bands 24 -> 64 (1e6e121): a full-screen repaint went from ~26 transfers to ~10 with no change on device, so burst count is not the mechanism. - XIP-off (0695ca6): no change on device, so PSRAM bandwidth starving the DSI is not the mechanism either. Back to the configuration where map tiles were confirmed working. Kept the two changes that stand on their own: the framebuffer is blanked before the panel is switched on (it was streaming uninitialised PSRAM to the screen), and the WADA_P4_FLUSH_TRACE build gate. Standing evidence for whoever picks this up: the tracer shows every large band LVGL pushes is 0x0000 black, including through the boot window where the flash occurs, so the colour is never in the framebuffer and the UI layer is excluded.

A real touchscreen UI for your mesh radio. · open source · GPL-3.0
Touch-UI MeshCore companion-radio firmware for the LilyGo T-Deck / T-Deck Plus and Heltec V4 + TFT (ESP32-S3).
An LVGL touch UI — map, chat, contacts, channels, settings — split out of
meshcomod. The app depends on a
MeshCore fork via PlatformIO lib_deps.

Architecture
This repo holds only the app: the companion_radio glue, the ui-touch
LVGL UI, the two boards' glue/variants, and platformio.ini. The MeshCore
core is not vendored here — it's pulled as a library via lib_deps from the
ALLFATHER-BV/meshcomod monorepo
(the same repo as the non-touch firmware), pinned by a lean source-only core-*
git tag. The touch-app files this repo owns (TouchPrefsStore, WifiRuntimeStore,
the transports, …) are dropped from the lib via -DMC_VENDORED_TOUCH_APP so they
aren't compiled twice. The build is byte-identical to the original in-tree
meshcomod firmware.
Build
PlatformIO pulls the core fork and all libraries automatically:
pio run -e heltec_v4_tft_companion_radio_usb_tcp_touch # Heltec V4 TFT
pio run -e LilyGo_TDeck_companion_radio_touch # LilyGo T-Deck
# or just `pio run` to build both
Flash with the NVS-preserving 4-component chain (bootloader / partitions /
boot_app0 / firmware at 0x0 / 0x8000 / 0xe000 / 0x10000) so saved Wi-Fi
credentials survive — not a merged image, which 0xFF-pads and wipes NVS.

License
GPL-3.0-or-later — see LICENSE. wadamesh is copyleft: anyone who distributes a build or a fork must also make their source available under the GPL. This keeps the UI open and concentrates community effort instead of fragmenting it into closed forks.
wadamesh incorporates and depends on MeshCore (MIT, © Scott Powell / rippleradios.com) and other third-party components — see NOTICE for the full list and their licenses. MeshCore-derived files keep their MIT notices; the combined work is distributed under the GPL (MIT is GPL-compatible). The MeshCore fork that wadamesh builds against stays MIT on purpose, so its Wi-Fi/BLE hooks remain upstreamable to MeshCore.
