In the previous article, I briefly explained the code modification part involved in adding the recovery function. After the code is modified successfully, it is not equal to the required function, there are still a lot of problems to solve after compilation is completed to the target board!
After one day of hard work, Bootloader and recovery are added and compiled successfully. Aft

quite easy for us to draw a background. We enable face-to-face projection and draw a full screen image texture of the current frame. The following is the OpenGL ES1 code:

For fixed function hardware: OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification and emphasizes hardware acceleration of the API, but is fully backwards compatible with 1.0. it provides enhanced functionality, improved image quality and Optimizations to increase performance while loading cing memory bandwidth usage to save power. the OpenGL ES 1.1 extension pack is a collection of optional extensions added to OpenGL ES

Ordsets is an ordered set implemented by lists. because changes to data elements trigger re-sorting, ordsets is inefficient and only applicable to scenarios with small data volumes. ordsets contains common set operations: intersection, union, whether it is a subset, and whether there is an intersection

In practical applications, when we want to hand over a project to the customer, we need to clear all the previous test data of all tables in the database to give the customer a clean database, if there are many tables involved, it takes not only time to clear them one by one, but also prone to errors and missing/deleted. Here I provide a method, you can quickly and effectively clear data in all tables of a specified database. For your reference only.
