Figure 6. LINUX software architecture
Figure 6 shows the LINUX software architecture. Normally the chip solution company will provide Driver layer and Hardware layer code for user's reference. There are many open source codes that related to Middleware and Application layer in the internet, user can capture the code and compile it through some procedure. This chapter will introduce how to compile open source code and install in SP7021 platform.
User should prepare a LINUX OS base PC (OS is Ubuntu 18.04) for cross compile open source application code. Once compiling is ready, user has two ways to execute the application (APP).

- sudo apt-get install kernel-package g++ u-boot-tools
