本手册为AM335x U-Boot用户提供详细的指导和参考信息,涵盖U-Boot的基本概念、配置方法及常见问题解决策略。
In the AM335x processor, the ROM code acts as a bootstrap loader, often called the Initial Program Loader (IPL) or Primary Program Loader (PPL). The boot process is completed in two consecutive stages using U-Boot binaries. The binary for the first stage of U-Boot is referred to as the Secondary Program Loader (SPL) or MLO. The binary for the second stage of U-Boot is simply called U-Boot. SPL is a non-interactive loader and is a specially built version of U-Boot, which is compiled concurrently when building U-Boot.
