详细说明： Hardware verification engineers often run bare-metal tests to verify core-related function in a System on Chip (SoC). However, it can be challenging to write boot code for a bare-metal system, without a basic understanding of software development on the ARM architecture. This application note provides code examples for the following important operations that are involved in booting a bare-metal system: • Initializing exceptions. • Initializing registers. • Configuring the MMU and caches. • Enabling NEON and Floating Point. • Cha nging Exception levels. The code examples are written with the GNU assembly grammar and are tested on the Cortex-A53, Cortex-A72, and Cortex-A73 processors. They also apply to other ARMv8-A processors. ...展开收缩
