## 🎯 Key Features Implemented
### 1. Partition-Based Extension System
- Uses existing OTA partitions (app0/app1)
- No partition table changes required
- Maintains OTA update compatibility
### 2. Manual Partition Swap Return
- **NOT** using bootloader rollback (disabled in Arduino ESP32)
- Uses `esp_ota_set_boot_partition()` + `esp_restart()`
- Dynamic partition detection (handles "ping-pong" problem)
### 3. RTC Boot Counter Watchdog
- Prevents soft-brick from bad extensions
- Auto-return to launcher after 3 failed boots
- Resets counter on successful user-initiated exit
### 4. Safety Guardrails
- Battery check (>20%) before flashing
- Magic byte validation (0xE9)
- Partition size validation
- File existence checks
- Error handling with user-friendly messages
### 5. SD Card App Structure
```
/.crosspoint/apps/{app-name}/
├── app.json # Manifest (name, version, description, author, minFirmware)
└── app.bin # Compiled firmware binary
```
### 6. UI Integration
- Apps menu in HomeActivity (after File Transfer)
- App list with selection highlight
- Progress bar during flashing
- Button hints (Back, Launch, Up, Down)
---
## 🧪 Testing
### Quick Test Steps
1. **Prepare SD Card**:
```bash
mkdir -p /.crosspoint/apps/hello-world
# Copy app.json (see TESTING_GUIDE.md)
# Copy and rename firmware.bin to app.bin
```
2. **Flash Main Firmware**:
```bash
pio run -t upload
```
3. **Test Flow**:
- Home → Apps → Select Hello World → Launch
- See "Flashing App..." progress bar
- Device reboots into Hello World
- Press Back → Returns to Home
### Full Testing
See **TESTING_GUIDE.md** for comprehensive testing procedures including:
- Safety feature validation
- Ping-pong state testing
- Error case handling
- Troubleshooting guide

## 📊 Build Statistics
### Main Firmware
- **RAM**: 32.4% (106KB / 327KB)
- **Flash**: 91.7% (6.0MB / 6.5MB)
- **Status**: ✅ SUCCESS
### Hello World Extension
- **RAM**: 19.0% (62KB / 327KB)
- **Flash**: 4.8% (315KB / 6.5MB)
- **Status**: ✅ SUCCESS
---
## ⚠️ Known Limitations
1. **No Bootloader Rollback**: Arduino ESP32 has rollback disabled, so we use manual partition swap
2. **No Sandboxing**: Extensions have full hardware access (trusted apps only)
3. **Flash Wear**: Each app switch writes to flash (limited erase cycles)
4. **Single App Slot**: Only one extension can be loaded at a time
5. **No App Icons**: Phase 2 feature
6. **No WiFi Download**: Phase 2 feature
---
## 🔮 Phase 2 Roadmap
### Features to Add
- [ ] **Chess Puzzles Extension**: Extract from main firmware
- [ ] **WiFi Download**: HTTP download to SD card
- [ ] **App Icons**: Display icons from manifest
- [ ] **App Store Server**: Remote app repository
- [ ] **Multiple Apps**: Support for many extensions
- [ ] **App Deletion**: Remove apps from SD
- [ ] **Version Checking**: Enforce minFirmware requirement
### Architecture Decisions for Phase 2
- Consider adding app2/app3 partitions for more slots
- Implement proper sandboxing if possible
- Add app signature verification for security
---
## 🐛 Debugging
### Serial Output Key
```
[AppLoader] SD card not ready
[AppLoader] Apps directory not found
[AppLoader] Found X apps
[AppLoader] Battery: XX% - OK/TOO LOW
[AppLoader] Flashing to partition: ota_X
[AppLoader] Flash complete. Rebooting...
[HelloWorld] Starting...
[HelloWorld] Activity started
[HelloWorld] Triggering return to launcher...
```
### Common Issues
1. **"No apps found"**: Check SD card path and app.json validity
2. **Flash fails**: Check battery level, partition size, magic byte
3. **Boot loop**: RTC watchdog should catch this (auto-return after 3 tries)
4. **Return fails**: Check partition swap logic in HelloWorldActivity

# Xteink X4 Extension System Testing Guide
## Pre-Test Setup
### Prerequisites
- Xteink X4 device with USB-C cable
- SD card (formatted as FAT32)
- Computer with PlatformIO installed
- Serial monitor (VS Code or `pio device monitor`)
### Files You Need
1. **Main firmware**: `.pio/build/default/firmware.bin`
2. **Hello World extension**: `.pio/build/hello-world/firmware.bin`
3. **Test app manifest**: `app.json`
---
## Step 1: Prepare the SD Card
### 1.1 Create Directory Structure
On your computer, create this folder structure on the SD card:
```
/.crosspoint/apps/hello-world/
```
### 1.2 Create App Manifest
Create file `/.crosspoint/apps/hello-world/app.json` with content:
```json
{
"name": "Hello World",
"version": "1.0.0",
"description": "Test extension for CrossPoint",
"author": "Test User",
"minFirmware": "0.14.0"
}
```
### 1.3 Copy Hello World Binary
1. Build Hello World: `pio run -e hello-world`
2. Copy `.pio/build/hello-world/firmware.bin` to SD card
3. Rename it to `app.bin` on the SD card:
```
/.crosspoint/apps/hello-world/app.bin
```
---
## Step 2: Flash Main Firmware
### 2.1 Build Main Firmware
```bash
pio run
```
### 2.2 Upload to Device
Connect Xteink X4 via USB-C and run:
```bash
pio run -t upload
```
### 2.3 Verify Boot
Open serial monitor:
```bash
pio device monitor -b 115200
```
You should see:
```
[ 0] [ ] Starting CrossPoint version 0.14.0-dev
```
---
## Step 3: Test the Apps Menu
### 3.1 Navigate to Apps Menu
1. Power on the device
2. You should see the Home screen with menu items:
- Continue Reading (if applicable)
- Browse Files
- OPDS Library (if configured)
- File Transfer
- **Apps** ← New menu item
- Settings
3. Use **Down** button to navigate to "Apps"
4. Press **Select** button
### 3.2 Expected Behavior
- AppsActivity should load
- Screen shows "Hello World v1.0.0" in the list
- "No apps found" message should NOT appear
---
## Step 4: Test App Flashing
### 4.1 Launch Hello World
1. In AppsActivity, "Hello World" should be highlighted
2. Press **Select** button
3. Screen should show "Flashing App..." with progress bar
4. Progress should go from 0% to 100%
### 4.2 Verify Serial Output
Check serial monitor for:
```
[xxxxx] [AppLoader] Flashing to partition: ota_X (offset: 0xYYYYYY)
[xxxxx] [AppLoader] Battery: XX% - OK
[xxxxx] [AppLoader] Writing chunk X/Y
[xxxxx] [AppLoader] Flash complete. Rebooting...
```
### 4.3 Device Reboots
- Device should automatically reboot
- Should boot into Hello World app (not main firmware)
- Screen shows "Hello World!"
---
## Step 5: Test Return to Launcher
### 5.1 Exit via Back Button
1. While in Hello World, press **Back** button
2. Device should reboot
3. Should return to main CrossPoint launcher (HomeActivity)
### 5.2 Verify Return
- Screen shows HomeActivity (not Hello World)
- All menu items visible
- Serial shows:
```
[HelloWorld] Triggering return to launcher...
```
### 5.3 Alternative: Power Button
1. Go back to Apps → Launch Hello World
2. Press **Power** button to sleep
3. Press **Power** again to wake
4. Should return to launcher
---
## Step 6: Test Safety Features
### 6.1 RTC Watchdog (Boot Loop Protection)
**⚠️ WARNING: This test simulates a crash. Have USB cable ready.**
To simulate a bad extension:
1. Create a dummy `/.crosspoint/apps/crash-test/app.json`
2. Copy a corrupted or incompatible `app.bin` (can use random bytes)
3. Try to launch it
4. Device will boot, crash, and reboot
5. After 3 failed boots, should auto-return to launcher
**Expected**: Device returns to launcher after 3 failed attempts, not stuck in boot loop.
### 6.2 Low Battery Protection
1. Discharge device to < 20% battery
2. Try to launch an app
3. Should show error: "Battery too low (XX%). Charge to continue."
4. Flash should NOT proceed
### 6.3 Missing app.bin
1. Delete `/.crosspoint/apps/hello-world/app.bin` (keep app.json)
2. Try to launch Hello World
3. Should show error: "app.bin not found"
4. Should NOT crash
---
## Step 7: Test Ping-Pong States
### 7.1 Check Current Partition
In serial monitor during boot:
```
esp_ota_get_running_partition() = ota_0 (or ota_1)
```
### 7.2 Test from ota_0
1. If running from ota_0: Launch Hello World → Return
2. Verify successful cycle
### 7.3 Force OTA Update to Swap Partitions
1. Perform a normal OTA update (or use debug tool)
2. This moves launcher to ota_1
3. Reboot and verify launcher now on ota_1
### 7.4 Test from ota_1
1. Launch Hello World from Apps menu
2. Verify it flashes to ota_0
3. Exit and return
4. Verify successful return to ota_1
**Critical**: Return must work regardless of which partition launcher is on.
---
## Expected Serial Output Summary
### Normal Operation
```
[ 0] [ ] Starting CrossPoint version 0.14.0-dev
[AppsActivity] Found 1 apps
[AppsActivity] Launching app: Hello World
[AppLoader] Flashing to partition: ota_1 (offset: 0x650000)
[AppLoader] Battery: 85% - OK
[AppLoader] Flash complete. Rebooting...
[HelloWorld] Starting...
[HelloWorld] Activity started
[HelloWorld] Triggering return to launcher...
```
### Error Cases
```
[AppLoader] Battery: 15% - TOO LOW
[AppLoader] Aborting flash
[AppLoader] Magic byte check failed: expected 0xE9, got 0xXX
[AppLoader] Invalid firmware image
[AppsActivity] No apps found
```
---
## Troubleshooting
### Issue: Apps menu not showing
**Solution**: Verify `onGoToApps` callback passed to HomeActivity in main.cpp
### Issue: "No apps found" message
**Check**:
- SD card mounted properly
- `/.crosspoint/apps/` directory exists
- `app.json` is valid JSON
- File permissions (readable)
### Issue: Flash fails with "partition error"
**Check**:
- `esp_ota_get_next_update_partition()` returns correct slot
- Not trying to flash to currently running partition
- File size < partition size (6.4MB)
### Issue: Return to launcher fails
**Check**:
- Hello World calls `esp_ota_set_boot_partition()` before `esp_restart()`
- Bootloader not corrupted
- RTC memory accessible
### Issue: Boot loop after flashing bad app
**Recovery**:
1. Hold Power button for 10 seconds
2. Connect USB cable
3. Flash good firmware via `pio run -t upload`
---

# App / Extension Architecture
This document explains how CrossPoint apps (aka extensions) work today, and how we can evolve toward an on-device app store.
## Current Model: Partition-based apps
CrossPoint runs as the main firmware, and apps are installed by flashing a standalone firmware image into the device's *other* OTA partition.
### Components
- **Apps directory** (SD): `/.crosspoint/apps/<appId>/`
- `app.json`: manifest (name/version/author/minFirmware...)
- `app.bin`: firmware image for the app (ESP32-C3)
- **Launcher UI** (device): Home → Apps
- lists apps discovered on SD
- installs/launches apps by flashing `app.bin`
- **AppLoader**: SD scan + OTA flashing
- **File Transfer Web UI**: developer workflow for uploading apps without removing SD
### End-to-end flow
```text
Developer builds app firmware -> app.bin
|
| (WiFi) upload via File Transfer /apps (developer page)
v
SD card: /.crosspoint/apps/<appId>/{app.bin, app.json}
|
| (device UI) Home -> Apps -> select app -> Install
v
AppLoader flashes app.bin to next OTA partition, sets boot partition, reboots
|
v
Device boots into the app firmware
```
### Why this aligns with extension requests
This keeps out-of-scope features (games/puzzles, experimental tools) out of the core reader firmware while still allowing the community to build and run them.
This is directly aligned with:
- Discussion #257: "extension/plugin support" requests
- Discussion #575: chess interest + feedback that games should not live in the core firmware
## Future: On-device app store (proposed)
The current system requires getting `app.bin` onto the SD card.
An on-device app store would automate that step by downloading releases and assets over WiFi.
### Proposed pieces
1) **Registry**
- `apps.json` listing available apps with metadata and download URLs.
- Maintainer choice:
- separate repo (recommended) `crosspoint-reader/app-registry`
- or keep `apps.json` in the firmware repo
2) **Release assets**
- Required: `app.bin`
- Optional: `assets.zip` (unpacks to `/.crosspoint/<appId>/...`)
- Optional: `app.json` (manifest) if authors prefer to author it directly
3) **Device-side store UX** (follow-up work)
- Fetch registry over HTTPS
- Download `app.bin` + optional `assets.zip` to SD
- Unpack assets to expected paths
- Surface install/update actions via Home → Apps
### Why assets.zip matters
Many apps need more than a binary (sprites, fonts, puzzle packs).
For production UX, users should not have to manually place these files.
Bundling assets as a separate downloadable archive keeps the app firmware small while enabling a 1-click install experience.

# Apps (Extensions) and Developer Workflow
CrossPoint supports **apps/extensions** that live on the SD card and are installed by flashing their firmware image into the device's unused OTA partition.
This is intentionally designed so out-of-scope apps (games, puzzles, etc.) do **not** need to be included in the core reader firmware.
## What is an "app"?
An app is a **standalone firmware binary** (ESP32-C3) with a small manifest.
SD card layout:
```
/.crosspoint/apps/<appId>/
app.bin # app firmware image (ESP32-C3; starts with magic byte 0xE9)
app.json # manifest (name, version, ...)
```
The CrossPoint launcher discovers apps by scanning `/.crosspoint/apps/*/app.json`.
## Installing an app (on device)
1. Home → Apps
2. Select the app
3. Press Launch/Install
CrossPoint will flash `app.bin` to the OTA partition and reboot.
## Fast iteration: upload apps over WiFi (no SD card removal)
Use the File Transfer feature:
1. On device: Home → File Transfer
2. Connect to WiFi (STA) or create a hotspot (AP)
3. From your computer/phone browser, open the URL shown on the device
4. Open **Apps (Developer)**
5. Fill in:
- App ID (e.g. `chess-puzzles` or `org.example.myapp`)
- Name
- Version
- Optional: author, description, minFirmware
6. Upload your app binary (`app.bin`)
7. On device: Home → Apps → select app → Install
Notes:
- This page is upload-only. Installing always happens on device.
- The Apps (Developer) page writes to `/.crosspoint/apps/<appId>/` and generates `app.json`.
## Building apps with the community SDK
Recommended SDK: `https://github.com/open-x4-epaper/community-sdk`
Typical setup (in your app repo):
1. Add the SDK as a submodule:
```bash
git submodule add https://github.com/open-x4-epaper/community-sdk.git open-x4-sdk
```
2. In `platformio.ini`, add SDK libs as `lib_deps` (symlink form), for example:
```ini
lib_deps =
BatteryMonitor=symlink://open-x4-sdk/libs/hardware/BatteryMonitor
EInkDisplay=symlink://open-x4-sdk/libs/display/EInkDisplay
SDCardManager=symlink://open-x4-sdk/libs/hardware/SDCardManager
InputManager=symlink://open-x4-sdk/libs/hardware/InputManager
```
3. Build with PlatformIO:
```bash
pio run
```
4. The firmware binary will usually be:
- `.pio/build/<env>/firmware.bin`
For CrossPoint app uploads:
- Rename/copy your output to `app.bin`, then upload via the Apps (Developer) page.
## Example: Hello World app
This repo includes a minimal Hello World app that can be built as a standalone firmware image and installed via the Apps menu.
Build:
```bash
.venv/bin/pio run -e hello-world
```
Upload the output:
- File: `.pio/build/hello-world/firmware.bin`
- Upload via: File Transfer → Apps (Developer)
- Suggested App ID: `hello-world`
Then install on device:
Home → Apps → Hello World → Install
## Distribution (proposed)
Apps should live in their own repositories and publish binaries via GitHub Releases.
For safety/auditability, registry listings should reference a public source repository (e.g. GitHub URL) so maintainers and users can review the code that produced the release.
Release assets:
- Required: `app.bin`
- Optional: `app.json`
Registry location (maintainer choice):
1. Separate repo (recommended): `crosspoint-reader/app-registry` containing `apps.json`
2. Or keep `apps.json` in the main firmware repo
The on-device store UI can be built later on top of this ecosystem.
