Based on the [LCSC Taishanpai Development Board] small mobile phone project

This project replicates the "Fat Girl Mobile Phone" training camp from Taishan School. In the process, you can learn how to set up a Linux virtual machine environment, commonly used Linux commands, SDK compilation, device trees, and MIPI screen debugging.

1. Project Introduction
This project introduces the replication process of the Taishanpai development board project "Fat Girl Phone," providing assistance to those who also want to replicate it.
2. Project Materials
The project materials include official documents and video tutorials provided by LCSC development board. The materials detail the environment setup and device tree parameter modification process, and provide code patches and assembly tutorials in Chapter 7, the comprehensive mobile phone project.
    Documentation Tutorials: "Fat Girl Phone" Practical Project Materials
    Video Tutorials: Collection · "Taishanpai Training Camp" LCSC · Taishanpai RK3566 Linux Development Board
3. Schematic Diagram Explanation
The adapter board's function is to connect a 3.1-inch screen to the Taishanpai and provide backlight voltage to the screen. The schematic diagram includes: MIPI interface, touch interface, backlight circuit, and audio interface.
Detailed schematic diagram explanation Refer to the document: Circuit Principle Analysis
1. MIPI Interface
    Since the MIPI interface type and wiring sequence of the 3.1-inch screen and the Taishanpai development board are inconsistent, an adapter is required. 1. **Adapter Board:** Connects the 3.1-inch screen to the Taishanpai's MIPI interface. The type and wiring sequence of the adapter board's interface are determined by the screen and the Taishanpai's MIPI interface.
2. **Touch Interface:** The adapter board
    connects the screen's touch interface to the Taishanpai's touch interface.
3. **Backlight Circuit:** The
    backlight circuit mainly consists of a backlight selection circuit, a backlight drive circuit, and a backlight adjustment circuit. Note that components marked NC in the schematic do not need to be soldered.
4. **Audio Interface:**
    The audio interface consists of a speaker and microphone jack.
4. Replication Process
Computer Configuration:
Laptop Model: Acer Swift 3 RTX3050
CPU: AMD Ryzen 7 5800U with Radeon Graphics 1.90 GHz
Memory: 16GB
Hard Drive: Reserved 500GB SSD
4.1 Environment Setup
Reference Documents: Environment Setup
Step 1: Install Ubuntu virtual machine using VirtualBox, refer to 【VirtualBox】Ubuntu Compilation Environment Setup
Step 2: Set up Samba, refer to Samba Setup
4.2 SDK Compilation
Reference Documents: Android 11 SDK
Step 1: Download SDK
Step 2: Complete verification, decompression, code synchronization, and compilation environment installation
Step 3: Full compilation of Android 11
During the compilation process in step 3, the following two errors occurred
: ninja failed with: exit status 137
ninja failed with: exit status 1
Refer to the following materials to solve the errors:
Reference 1: Common Problem Solutions for Compiling Android 4/5/6/7/8/9/10/11 System Source Code on Ubuntu 18.04/20.04 Virtual Machine
Reference 2: ninja failed with: exit status The steps to resolve issue 137
are as follows:
1. In VirtualBox, set the installed virtual machine's memory to 12GB and the processor to 8 cores
. 2. Set JavacHeapSize to 6GB, following the solution in Reference 1.
3. Set swap to 32GB, following the solution in Reference 2.
4. Recompile using `make j-4`. The compilation should take approximately 6 hours. The steps are:
`cd u-boot && ./make.sh rk3566 && cd ../kernel && make clean && make distclean && make ARCH=arm64 tspi_defconfig rk356x_evb.config android-11.config && make ARCH=arm64 tspi-rk3566-user-v10.img -j4 && cd .. && source build/envsetup.sh && lunch rk3566_tspi-userdebug && make installclean -j4 && make -j4 && ./mkimage.sh`

4.3 Applying the code patch and completing kernel compilation:
Step 1: Download the complete patch, 1.4.5 complete code patch (3.1-inch screen touch driver patch.zip).
Step 2: After decompression, find the following files and replace the compiled files using Samba
: "tspi-rk3566-dsi-v10.dtsi" and "tspi-rk3566-user-v10.dts" in the rockchip folder
; "Makefile" and "my_touch" in the touchscreen folder
; "Makefile" and "my_gp7101_bl" in the backlight folder.
Note that line 54 of the "Makefile" in the provided touchscreen folder needs to be modified.
The original file should be:
obj-$(CONFIG_TOUCHSCREEN_GSL3673) += gsl3673-ts.o
obj-y += my_touch/
Modify it to:
obj-$(CONFIG_TOUCHSCREEN_GSL3673) += Step
3
: Compile the kernel separately, refer to Compiling the Kernel Separately with Android 11 SDK (only suitable for versions with eMMC).
4.4 PCB fabrication, purchasing components, soldering, 3D printing the shell, assembly.
Reference: VII. Comprehensive Mobile Phone Project (3. Free PCB Prototyping, 4. PCB Soldering Practice, IV. Shell)
4.5 Flashing
Step 1: Download Rockchip Development Tool v2.92, Chapter 7. [LCSC·Taishanpai RK3566] Development Tool
Step 2: Import the configuration "Android_All_Config.cfg" into the Rockchip Development Tool, refer to Compiling Android 11.
Step 3: Select all and choose the path, except for boot.The image file is located in the kernel folder, while the others are located in the rockdevImage-rk3566_tspi folder.
Step 4: Burn the program.

[Based on Taishanpai - Fat Girl's Little Phone] 7394266A

Based on the Taishanpai development board and expansion board launched by JLCPCB, along with a series of live broadcasts, recorded videos, and document tutorials, we guide electronics enthusiasts and open source supporters to quickly get started with Linux, understand the Linux project development process, work on projects together, and have fun together.

I. Project Introduction
       Following this training camp was my first step into Linux. Through this project, I learned the basic Linux framework, development environment setup, commonly used Linux commands, simple driver debugging, device tree concepts, and I also learned to draw PCB diagrams and debug driver code, gaining a preliminary framework for debugging a product.
