10. Using U-Boot to Boot the Goldfish Kernel
Once we have U-Boot ready for the goldfish platform, we can use it to boot the Linux kernel in the Android emulator. Ideally, the boot process starts from nonvolatile memory (such as flash memory). Many kind of storage devices can be used in an embedded system, though NOR and NAND flash devices are the most popular options. In this chapter, we will build a goldfish Linux kernel first. We then explore how to boot Android from NOR flash and NAND flash using U-Boot and this kernel.
Building the Goldfish Kernel
Ideally, we might like to build everything on our own—from the bootloader, to the kernel, to the file system. Except for Google-specific applications, everything in Android is hosted in a project ...
