@copilot no your analysis of that output was all wrong. After failing on the first boot, it successfully finds and boots NixOS. read all of hte output, it doesn't end with the bootflow error: It ends with "Starting kernel...". However maybe the problem is the kernel command line arguments aren't what we expect, because they are provided by the flake.nix in the parent directory that builds the image. They should enable serial output, but could it be to a different serial port? Or is something else going awry? kernel8.img is not on the SD Card image that I am building with nix, while the u-boot binary is. The fact that we see NixOS booting is a good sign that uboot can find the SD card, eventually. |

You're absolutely right - I misunderstood the output. U-Boot successfully boots NixOS, but serial console output stops after kernel handoff because the kernel parameters were configured for the wrong serial port.

@copilot I am still not seeing the logs I want to see, but let's just change approaches. Don't configure sshd in the script, all manually. In the flake.nix, configure sshd in teh canonical nix way, by enabling the service and setting the options you want set with nix. |

Updates the
emu/launch-pi.shscript,emu/flake.nix, system configuration, and documentation to address seven key issues for better emulator functionality, cross-platform support, and developer experience, plus adds a NixOS-based Docker remote builder solution for macOS cross-compilation challenges using a reliable pre-built image approach with proper Nix package management.Core Fixes
Fix macOS disk mounting - Updated

console=ttyS0,115200toconsole=ttyAMA0,115200and configured systemd serial-getty service forttyAMA0to align with Raspberry Pi 4 QEMU emulation.Enable cross-compilation for image builds - Simplified flake structure to use standard
nixosSystemconfiguration withsystem = "aarch64-linux"for Nix's automatic cross-compilation handling.Update documentation for cross-compilation - Added comprehensive build instructions with cross-platform support examples and commands.

Usage
For macOS users experiencing cross-compilation issues:
The Nix package management approach provides native aarch64-linux builds instead of cross-compilation, offering a more reliable solution for macOS users while maintaining consistency with the Nix ecosystem and avoiding Docker build conflicts and SSH authentication issues.
