- Fix CoreS3 boot failure (I2C now returns bool instead of err_result_t) - Flashing scripts now erase before flashing (to ensure it's a clean install) - M5Stack Core2 and CoreS3: Experimental SPI speed increase

# Issues
|
|
- WiFi bug: when pressing disconnect while between `WIFI_EVENT_STA_START` and `IP_EVENT_STA_GOT_IP`, then auto-connect becomes active again.
|
|
- ESP32 (CYD) memory issues (or any device without PSRAM):
|
|
- Boot app doesn't show logo
|
|
- WiFi is on and navigating back to Desktop makes desktop icons disappear
|
|
- WiFi might fail quietly when trying to enable it: this shows no feedback (force it by increasing LVGL buffers to 100kB)
|
|
Possible mitigations:
|
|
- When no PSRAM is available, use simplified desktop buttons
|
|
- Add statusbar icon for memory pressure.
|
|
- Show error in WiFi screen (e.g. AlertDialog when SPI is not enabled and available memory is below a certain amount)
|
|
- Clean up static_cast when casting to base class.
|
|
- M5Stack CoreS3 SD card mounts, but cannot be read. There is currently a notice about it [here](https://github.com/espressif/esp-bsp/blob/master/bsp/m5stack_core_s3/README.md).
|
|
- EventFlag: Fix return value of set/get/wait (the errors are weirdly mixed in)
|
|
- Consistently use either ESP_TARGET or ESP_PLATFORM
|
|
- tt_check() failure during app argument bundle nullptr check seems to trigger SIGSEGV
|
|
- Fix bug in T-Deck/etc: esp_lvgl_port settings has a large stack size (~9kB) to fix an issue where the T-Deck would get a stackoverflow. This sometimes happens when WiFi is auto-enabled and you open the app while it is still connecting.
|
|
- M5Stack Core only shows 4MB of SPIRAM in use
|
|
|
|
# TODOs
|
|
- Make a ledger for setting CPU affinity of various services and tasks
|
|
- Make "blocking" argument the last one, and put it default to false (or remove it entirely?): void startApp(const std::string& id, bool blocking, std::shared_ptr<const Bundle> parameters) {
|
|
- Boot hooks instead of a single boot method in config. Define different boot phases/levels in enum.
|
|
- Add toggle to Display app for sysmon overlay: https://docs.lvgl.io/master/API/others/sysmon/index.html
|
|
- CrashHandler: use "corrupted" flag
|
|
- CrashHandler: process other types of crashes (WDT?)
|
|
- Call tt::lvgl::isSyncSet after HAL init and show error (and crash?) when it is not set.
|
|
- Create different partitions files for different ESP flash size targets (N4, N8, N16, N32)
|
|
- Attach ELF data to wrapper app (as app data) (check that app state is "running"!) so you can run more than 1 external apps at a time.
|
|
We'll need to keep track of all manifest instances, so that the wrapper can look up the relevant manifest for the relevant callbacks.
|
|
- T-Deck: Clear screen before turning on blacklight
|
|
- Audio player app
|
|
- Audio recording app
|
|
- T-Deck: Use knob for UI selection
|
|
- Crash monitoring: Keep track of which system phase the app crashed in (e.g. which app in which state)
|
|
- AppContext's onResult should pass the app id (or launch request id!) that was started, so we can differentiate between multiple types of apps being launched
|
|
- Loader: Use main dispatcher instead of Thread
|
|
- Create more unit tests for `tactility-core` and `tactility` (PC-only for now)
|
|
- Show a warning screen if firmware encryption or secure boot are off when saving WiFi credentials.
|
|
- Show a warning screen when a user plugs in the SD card on a device that only supports mounting at boot.
|
|
- Localisation of texts (load in boot app from sd?)
|
|
- Explore LVGL9's FreeRTOS functionality
|
|
- External app loading: Check version of Tactility and check ESP target hardware, to check for compatibility.
|
|
- Scanning SD card for external apps and auto-register them (in a temporary register?)
|
|
- tt::app::start() and similar functions as proxies for Loader app start/stop/etc.
|
|
- Support hot-plugging SD card
|
|

# Nice-to-haves
|
|
- OTA updates
|
|
- Web flasher
|
|
- T-Deck Plus: Create separate board config?
|
|
- Support for displays with different DPI. Consider the layer-based system like on Android.
|
|
- Make firmwares available via web serial website
|
|
- If present, use LED to show boot/wifi status
|
|
- T-Deck Power: capacity estimation uses linear voltage curve, but it should use some sort of battery discharge curve.
|
|
- Statusbar widget to show how much memory is in use?
|
|
- Wrapper for Slider that shows "+" and "-" buttons, and also the value in a label.
|
|
- Display app: Add toggle to display performance measurement overlay (consider showing FPS in statusbar!)
|
|
- Files app: copy/paste actions
|
|
- On crash, try to save current log to flash or SD card? (this is risky, though, so ask in Discord first)
