+# LLDB Usage Guide
+## Overview
+Low Lever Debugger (LLDB) is a next-generation high-performance debugger.
+
+LLDB is developed based on the [llvm15.0.4](https://github.com/llvm/llvm-project/releases/tag/llvmorg-15.0.4) and supports debugging on the home screen and OpenHarmony devices or simulators.
+## How to Obtain
+Obtain the OpenHarmony SDK from http://ci.openharmony.cn/dailys/dailybuilds.
+
+LLDB is in the following path of the SDK:
+```
+\ohos-sdk\[system]\native\llvm
+```
+The value of **system** can be **windows**, **linux**, or **darwin**.
+
+For example, for Windows, **lldb.exe** is stored in the following path after the SDK is decompressed:
+```
+\ohos-sdk\windows\native\llvm\bin
+```
+
+## Supported Platform and Architecture
+
+### Local Debugging
+#### Example: Local Debugging on the Linux Platform
+1. Obtain the name of the executable file with debugging information generated by the clang compiler of the same version as LLDB.
+
+2. Run the following command in the terminal window to specify the name of the file to debug:
+
+   ```
+   ./lldb filename
+   ```
+
+3. Set a breakpoint at the **main** function in the code and run the following command on the LLDB interface:
+
+   ```
+   (lldb) b main
+   ```
+
+4. Run the following command on the LLDB interface. The program will stop at the breakpoint:
+
+   ```
+   (lldb) run
+   ```
+
+5. Perform subsequent debugging operations.
+
+### Remote Debugging
+
+> **Note: During remote debugging, the LLDB server and LLDB must be used together.**
+- Debugging the OHOS device on the Windows platform (Arm architecture)
+- Debugging the OHOS device on the Windows platform (AArch64 architecture)
+- Debugging the simulator on the Windows platform
+- Debugging the OHOS device on the macOS (M1) platform (Arm architecture)
+- Debugging the OHOS device on the macOS (M1) platform (AArch64 architecture)
+- Debugging the simulator on the macOS (M1) platform
+- Debugging the OHOS device on the macOS (x86) platform (Arm architecture)
+- Debugging the OHOS device on the macOS (x86) platform (AArch64 architecture)
+- Debugging the simulator on the macOS (x86) platform
+- Debugging the OHOS device on the Linux platform (Arm architecture)
+- Debugging the OHOS device on the Linux platform (AArch64 architecture)
+
+#### Example: Remote Debugging the OHOS Device on the Linux Platform (Arm Architecture)
+
+1. Run the executable file with debugging information on the device.
+
+   ```
+   ./filename
+   ```
+
+2. Push the LLDB server to the device and run the LLDB server.
+
+   Command line window 1:
+
+   ```
+   hdc file send lldb-server /data/local/tmp
+   hdc shell ./data/local/tmp/lldb-server p --server --listen "*:8080"
+   ```
+
+   > **Note: /data/local/tmp is a directory on the device, and 8080 is a    listening port. Both of them can be customized.**
+
+3. Start LLDB in another window, select the remote OHOS device, and connect to it.
+
+   Command line window 2:
+
+   ```
+   ./lldb
+   (lldb) platform select remote-ohos
+   (lldb) platform connect connect://localhost:8080
+   ```
+
+4. Set breakpoints and perform debugging operations.
+
+   Command line window 2:
+
+   ```
+   (lldb) breakpoint set --file <filename> --line <linenum>
+   (lldb) process attach --name process-name
+   ```
+
+## Functions Provided by LLDB
+- Loading a program to LLDB
+- Setting a breakpoint
+- Setting an observation point
+- Starting or attaching to a program
+- Executing a control program
+- Checking the thread status
+- Checking the stack frame status
