Test IW612 WiFi reliability over multiple boots on latest Sentai build

[ajlennon]

Issue Description

Need to validate IW612 WiFi module reliability and stability across multiple boot cycles on the latest Sentai build to ensure consistent network connectivity for production deployments.

Background

• Hardware: imx8mm-jaguar-sentai with NXP IW612 WiFi module
• Component: NXP IW612 SDIO WiFi (nxpiw612-sdio machine feature)
• Concern: WiFi reliability across boot cycles for production stability

Test Requirements

Test Scope

• Boot Cycles: Minimum 50-100 boot cycles
• WiFi Operations: Connection establishment, data transfer, reconnection
• Network Scenarios: Different SSIDs, security types (WPA2/WPA3), signal strengths
• Power Scenarios: Cold boot, warm reboot, power cycle

Success Criteria

• Connection Success Rate: >95% successful WiFi connections on boot
• Stability: No kernel panics, driver crashes, or system hangs
• Performance: Consistent throughput and latency across boots
• Recovery: Automatic recovery from temporary connection failures

Test Environment

• Build: Latest Sentai factory image with current IW612 drivers
• Network: Controlled WiFi environment with known-good access points
• Monitoring: Serial console logging, network performance metrics
• Duration: Extended testing over multiple days

Implementation Plan

1. Setup Test Environment

   • Configure automated boot/reboot cycle testing
   • Set up network monitoring and logging
   • Prepare test access points with different configurations

2. Execute Test Scenarios

   • Cold boot reliability testing
   • Warm reboot stability testing
   • Network reconnection after temporary disconnection
   • Performance consistency across boots

3. Data Collection

   • Boot time to WiFi connection metrics
   • Connection failure rates and error patterns
   • Driver/firmware error logs
   • Network performance benchmarks

4. Analysis and Reporting

   • Identify any reliability issues or patterns
   • Document performance baselines
   • Recommend optimizations if needed

Expected Deliverables

• Test report with reliability metrics
• Performance baseline documentation
• Any identified issues with reproduction steps
• Recommendations for production deployment

Priority

High - Critical for production reliability and customer satisfaction
