Summary

This chapter covered a lot of ground. The Project Trailblazer engineers started with their known platforms: the Embedded Planet RPX-CLLF, the Brightstar Engineering MediaEngine, the Tri-M MZ104 x86 single-board computer, and the COTS PC. They developed seven target platform boot requirements, and then they learned about the Linux boot process and developed the target root filesystem. Instead of compiling the root filesystem programs themselves, the engineers decided to use the MontaVista Journeyman product, which contains compiled binaries for all the target platforms. They developed the buildrootfilesystem script, which generates the target root filesystem and prepares it for use. On the way to booting their platforms, the engineers installed, configured, and started a TFTP server on tbdev1. This enabled them to boot the RPX-CLLF and MediaEngine. The MZ104 and COTS PC were also booted using a Flash IDE drive. Each target platform successfully booted and passed the seven target platform boot requirements. The engineers are ready to move on to remote debugging.
