This training course is ideal for engineers involved in developing software for platforms powered by the Arm® Cortex®-A5 application processors.
The learning is reinforced with unique Lab exercises which are run inside a self contained virtual machine environment. This allows the student to experience a real-life and project-ready development environment without the complexity of installing complex software prior to the class. This virtual machine is for the student to keep after the training class, allowing you to further experiment with embedded software development once the class has come to completion.
This course is aimed at software developers writing low level and bare-metal code for Armv7-A processors, concentrating on the Cortex-A5 processor, and at operating system developers who need to understand the details of the Arm v7A processors' architecture.
Delegates should have some understanding of embedded programming in C and assembler. Knowledge of other processors is a benefit but is not strictly required for attending this class.
This class uses training materials developed by Arm® and is complemented by Doulos' own lecture and laboratory material. This offers the students a well rounded and practical view of the topics covering both the processor's features along with how to program it.
