Server: Frame.panel_type (new column + migration) is auto-derived from
the device's reported board (X-Frame-Board), never user-set -- the
panel is a property of the hardware, not a picker in the UI.
image_pipeline's packing/render pipeline is parameterized by panel
geometry instead of hardcoded 800x480 globals, with the real confirmed
13.3in geometry (1600x1200) registered alongside the original 7.3in
panel. Existing 7.3in frames are unaffected (column default + board
mapping both resolve to the original panel).
Board identifiers are also renamed (devkit/xiao -> devkit_esp32c6/
xiao_esp32c6, plus new "ee02") since the EE02 board also carries a XIAO
module -- "xiao" alone stopped disambiguating hardware. The server
keeps accepting the legacy bare names indefinitely for already-flashed
devices.
Firmware: scaffolds a third build target (ee02, ESP32-S3 -- a real
chip-target change, not just a same-chip Kconfig variant like xiao) and
a new epd13in3e driver component skeleton. The actual panel init/LUT/
refresh register sequence isn't ported from vendor demo code yet (none
was available), so that component deliberately fails to compile
(#error) rather than risk sending unverified register values to real
hardware -- devkit/xiao are unaffected and build identically to before.
CI's ee02 build step is continue-on-error for the same reason.
- version.txt + esp_app_desc_t version reporting (X-Frame-Version header);
new ota_update.c checks the server's advertised version against the
running one and streams+applies an update via esp_https_ota, gated by
bootloader rollback (marks the image valid only after a full successful
cycle, so a bad update can't brick a wall-mounted frame).
- Dual-OTA partition tables: partitions.csv (8MB dev board, 2MB slots) and
new partitions_xiao.csv (4MB XIAO, 1.875MB slots -- the dev board's
table doesn't fit the XIAO's flash). New build_for_board.sh gives each
board its own build dir + generated sdkconfig via SDKCONFIG_DEFAULTS
layering, so switching boards never clobbers the other's config.
- fetch_photo_info()/fetch_face_labels() were using the short
reachability-check timeout even though the manage-menu path can be the
first (cold, TLS-handshake-paying) request of a wake cycle -- switched
to the longer fetch timeout to stop spurious ESP_ERR_HTTP_CONNECT
failures.
- XIAO: the RF switch that selects onboard vs. external antenna
(GPIO3/14) isn't initialized by plain ESP-IDF the way Seeed's Arduino
package does it, leaving WiFi unable to reliably reach the antenna at
all -- new board_antenna.c powers the switch and selects the onboard
antenna, gated behind FRAME_XIAO_ANTENNA_INIT (on by default in
sdkconfig.xiao). Also remaps the EPD DC/RST/BUSY pins, since the dev
board's defaults (GPIO9/10/11) aren't physically exposed on the XIAO.
