Some checks failed
CI / markdown-lint (push) Failing after 15s
- Added comprehensive hardware research documentation - Created bootloader analysis and driver compatibility research - Set up development environment with cross-compilation tools - Created Q20-specific device tree (simplified version) - Added kernel build scripts and configuration - Set up CI/CD pipeline with Gitea Actions - Added .gitignore for build artifacts

## Key Findings
|
|
- [ ] Bootloader signature verification method identified
|
|
- [ ] Device tree structure documented
|
|
- [ ] Kernel configuration extracted
|
|
- [ ] Proprietary drivers identified
|
|
- [ ] Firmware blobs catalogued
|
|
|
|
## Next Steps
|
|
1. Analyze bootloader security
|
|
2. Extract kernel configuration
|
|
3. Identify required drivers
|
|
4. Document hardware interfaces
|
|
5. Plan driver development
