How to use board level configuration¶
1. Overview¶
This document is a CI130X SDK board level adaptation document. It aims to introduce how developers can modify the SDK to adapt to a new board when using a non SDK standard board.
2. Instructions¶
Board level configuration code path: SDK driver boards
2.1. Code Structure¶
| Source file | Description |
|---|---|
| board_ default. C |
Weak definition interface of board level configuration |
| board.c board. H |
Board level configuration interface |
| board_ port_ template. C |
Example of board level configuration |
| CI-D06GT01D_ REV. c |
CI standard board D06GT01D configuration source file |
2.2. Steps to add a new board¶
When developers need to use a new board with no corresponding configuration source file in the SDK, they need to follow the steps below to add it. If there is already a configuration source file in the SDK, they just need to follow step 2 to associate the current board.
2.2.1. Step 1: Add Source File¶
Add a new board source file, such as CI-D06GT01D_ REV. c, adding method: copy board_ port_ template. C In SDK driver boards, rename it, and modify the content of the corresponding interface in the source file. If you need to add an interface, see step 3.
2.2.2. Step 2: Associate the new board source file¶
After adding the source file of a new board under SDK driver boards, you need to associate the source file of the new board with the current SDK by opening the project code and modifying the user_ BOORD in config. h_ PORT_ FILE macro definition enables new board level configuration source files to be associated.
#define BOARD_ PORT_ FILE "CI-D06GT01D_REV_V1.0. c"//The board level configuration source file is associated with CI-D06GT01D_ REV_ V1.0.c
2.2.3. Step 3: Add interface description¶
(1) Add an interface to the newly added configuration source file. The example source file is taken as an example in the figure.
(2) Add a function declaration to the boards. h file, as shown in the following figure.
(3) In borads_ Add virtual functions with the same name in default. c, as shown in the following figure.
