feat: add OTA firmware update for ESP32 platforms#54
Merged
Conversation
Extend the network abstraction layer with HTTP GET for lightweight requests (e.g. OTA version check JSON). Both ESP-IDF and RT-Thread backends implement the new function following the same pattern as the existing claw_net_post(). Signed-off-by: Chao Liu <chao.liu.zevorn@gmail.com>
Add Over-The-Air update support following the board-interface pattern (claw_ota.h), not OSAL abstraction — OTA is fundamentally a platform operation (flash write, partition switch, bootloader interaction). New components: - claw_ota.h: platform OTA callback interface - ota_service.c: version check, JSON parse, update worker thread - esp_ota.c: ESP-IDF implementation (esp_ota_ops A/B partition) - tool_ota.c: AI tools (ota_check, ota_update, ota_version, ota_rollback) - /ota shell command (check|update|rollback|version) Build integration: - Meson: -Dota=true feature flag, OTA URL/interval config overrides - Kconfig: CONFIG_RTCLAW_OTA_ENABLE for ESP32-C3 and S3 - CMake: app_update component dependency - sdkconfig: rollback enabled on xiaozhi-xmini and S3 default Target boards: xiaozhi-xmini (C3, 16MB) and ESP32-S3 default (16MB), both already have OTA dual-partition tables (ota_0 + ota_1 + otadata). Closes #53 Signed-off-by: Chao Liu <chao.liu.zevorn@gmail.com>
15 test cases covering OTA pure-logic functions: - version_compare: equal, major/minor/patch, mixed precedence - parse_version_json: full/minimal/spaced JSON, missing fields, empty input, field truncation - trigger_update: NULL and empty URL rejection - tool registration: all 4 OTA AI tools present Platform OTA functions are stubbed (no real flash needed). Test runner enables -Dota=true automatically via run.py. Signed-off-by: Chao Liu <chao.liu.zevorn@gmail.com>
On ESP-IDF the CONFIG_RTCLAW_OTA_ENABLE flag comes from Kconfig (sdkconfig → cross.ini), not from Meson -Dota=true. When sdkconfig enables OTA but Meson ota=false (the default), OTA call-sites in claw_init.c and shell_commands.c are active but OTA source files are missing, causing undefined reference errors at link time. Fix: always include ota_service.c, tool_ota.c, and test_ota.c in the build. The #ifdef CONFIG_RTCLAW_OTA_ENABLE inside each file controls whether any code is emitted. This matches the pattern used by swarm, sched, ai_engine, and other modules. Signed-off-by: Chao Liu <chao.liu.zevorn@gmail.com>
esp_ota.c was compiled into libmain.a, but the Meson-compiled ota_service.o (in librt_claw.a) references its symbols. ESP-IDF links librt_claw.a before libmain.a, so the linker cannot resolve claw_ota_platform_init, claw_ota_running_version, etc. Fix: compile esp_ota.c as part of the rt_claw component so all OTA symbols live in the same static library.

During firmware flashing/erasing, output now goes directly to the right-side Serial Monitor panel instead of a separate flash-log div. All serial controls (Connect, Reset, Clear, baudrate, input, Send) are disabled during flash to prevent conflicts, except the Expand button which remains usable.
