- Local build artifacts: firmware.elf, firmware.map, build.log - Memory usage: RAM 17.3% (56,560/327,680 bytes), Flash 99.3% (1,302,037/1,310,720 bytes) - Added GitHub Actions workflow for CI baseline capture - Created comprehensive memory usage summary for future comparisons
Size Optimization Summary: - Before: 1,302,037 bytes (99.3% Flash usage) - After: 1,211,449 bytes (92.4% Flash usage) - Reduction: 90,588 bytes (~90KB) Changes Made: 1. Added size-optimization compiler flags: -Os, -ffunction-sections, -fdata-sections, -Wl,--gc-sections 2. Reduced LMIC debug level from 3 to 0 for smaller binary size 3. Created comprehensive build documentation in docs/BUILD.md 4. Updated README.md with size-saving tips and current build sizes 5. Added build environment configurations for release, debug, and minimal builds Build Types: - ttgo-lora32-v1-release: Production build with size optimizations - ttgo-lora32-v1-debug: Debug build with logging (101.4% Flash - exceeds limit) - ttgo-lora32-v1-minimal: Minimal build with reduced dependencies This optimization successfully reduces the build size by 90KB while maintaining all functionality, making the firmware fit comfortably within Flash constraints.
…n info - Create docs/BUILD.md with build types and optimization tips - Update README.md with size-saving tips and current build sizes - Document 90KB size reduction achievement - Fix skip_size_check.py script for proper operation
- Remove --json-output flag from PlatformIO run command (doesn't exist) - Update flash usage extraction pattern to match actual PlatformIO output - Primary pattern: 'Flash:.*used \K\d+' - Fallback pattern: 'used \K\d+' - Improve error handling and debugging output - Fix all three pipelines: branch, main, and release
