# Phase 1 Implementation: Hardware Access & Bootloader Research
|
||||
|
||||
## Current Status
|
||||
Based on our research, we have comprehensive hardware specifications and bootloader analysis. Now we need to implement practical testing and development.
|
||||
|
||||
## Implementation Plan
|
||||
|
||||
### 1. Development Environment Setup
|
||||
|
||||
#### Required Tools
|
||||
- **Cross-compilation toolchain** for ARMv7
|
||||
- **QEMU** for ARM emulation
|
||||
- **Buildroot** for minimal rootfs
|
||||
- **Linux kernel source** (mainline + CAF patches)
|
||||
- **Device tree compiler** (dtc)
|
||||
- **Fastboot/ADB tools**
|
||||
|
||||
#### Setup Commands
|
||||
```bash
|
||||
# Install cross-compilation tools
|
||||
sudo apt install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf
|
||||
|
||||
# Install QEMU for ARM
|
||||
sudo apt install qemu-system-arm
|
||||
|
||||
# Install device tree compiler
|
||||
sudo apt install device-tree-compiler
|
||||
|
||||
# Install Android tools
|
||||
sudo apt install android-tools-fastboot android-tools-adb
|
||||
```
|
||||
|
||||
### 2. Minimal Kernel Configuration
|
||||
|
||||
#### Base Configuration
|
||||
- Start with `msm8960_defconfig` from mainline kernel
|
||||
- Add essential drivers for Q20 hardware
|
||||
- Enable debug interfaces and console output
|
||||
- Configure minimal filesystem support
|
||||
|
||||
#### Key Configurations
|
||||
```
|
||||
CONFIG_ARM=y
|
||||
CONFIG_CPU_32v7=y
|
||||
CONFIG_ARCH_MSM=y
|
||||
CONFIG_MSM8960=y
|
||||
CONFIG_SERIAL_MSM_CONSOLE=y
|
||||
CONFIG_MMC=y
|
||||
CONFIG_MMC_MSM=y
|
||||
CONFIG_DRM_MSM=y
|
||||
CONFIG_SOUND_MSM=y
|
||||
CONFIG_INPUT=y
|
||||
CONFIG_KEYBOARD_MSM=y
|
||||
```
|
||||
|
||||
### 3. Device Tree Development
|
||||
|
||||
#### Base Device Tree
|
||||
- Create `q20.dts` based on MSM8960 reference
|
||||
- Define memory map and CPU configuration
|
||||
- Add essential peripherals (UART, MMC, GPIO)
|
||||
- Configure display and input devices
|
||||
|
||||
#### Key Device Tree Nodes
|
||||
```dts
|
||||
/ {
|
||||
model = "BlackBerry Classic Q20";
|
||||
compatible = "blackberry,q20", "qcom,msm8960";
|
||||
|
||||
memory {
|
||||
device_type = "memory";
|
||||
reg = <0x0 0x80000000>;
|
||||
};
|
||||
|
||||
chosen {
|
||||
stdout-path = "serial0:115200n8";
|
||||
};
|
||||
};
|
||||
```
|
||||
|
||||
### 4. Minimal Root Filesystem
|
||||
|
||||
#### BusyBox-based Rootfs
|
||||
- Use Buildroot to create minimal rootfs
|
||||

|
||||
- Add network tools for debugging
|
||||
- Configure basic init system
|
||||
|
||||
#### Essential Packages

||||
dropbear (SSH server)
|
||||
iw (Wi-Fi tools)
|
||||
alsa-utils (audio)
|
||||
```
|
||||
|
||||
### 5. Boot Image Creation
|
||||
|
||||

||||
- Create `zImage` from kernel
|
||||
- Build minimal `initramfs`
|
||||
- Package as Android boot image
|
||||
- Test with QEMU first
|
||||
|
||||
#### Boot Image Structure
|
||||
```
|
||||
boot.img:
|
||||
├── kernel (zImage)
|
||||
├── ramdisk (initramfs)
|
||||
├── device tree (q20.dtb)
|
||||
└── second stage (optional)
|
||||
```
|
||||
|
||||
### 6. Testing Strategy
