BananaPro/Pi: Building U-Boot, script.bin and Linux kernel

Illustration for BananaPro/Pi: Building U-Boot, script.bin and Linux kernel documentation

Summary

Boot firmware and kernel builds are sensitive: a small misconfiguration can prevent boot. Use a serial console, keep backups, and validate changes in small steps.

Requirements

  • Serial console access
  • A reproducible build environment
  • A recovery path (known-good image or boot media)

Concrete example (confirm U-Boot is running)

Look for a U-Boot banner in serial output and confirm:
- board name
- DRAM size
- boot device
