11- HPM5300EVK Board Resources Introduction
12- Quickly Getting Started
13- Refreences
14
15By reading the Quickly Get Started section developers can quickly get their hands on this BSP and run RT-Thread on the board. More advanced features will be introduced in the Advanced Features section to help developers take advantage of RT-Thread to drive more on-board resources.

17## Board Resources Introduction
18
19HPM5300EVK is a development board based on the RISC-V core launched by HPMicro, with rich on-board resources and on-chip resources for motor control, etc.

39## Execution Instruction
40
41### Quickly Getting Started
42
43The BSP support being build via the 'scons' command, below is the steps of compiling the example via the 'scons' command
44
45#### Parpare Environment
46- Step 1: Prepare [RT-Thread ENV](https://www.rt-thread.org/download.html#download-rt-thread-env-tool)
47- Step 2: Prepare [toolcahin](https://github.com/helloeagleyang/riscv32-gnu-toolchain-win/archive/2022.04.12.zip)
48    - Download the package and extract it into a specified directory, for example: `C:\DevTools\riscv32-gnu-toolchain`
49- Step 3: Set environment variable `RTT_RISCV_TOOLCHAIN` to `<TOOLCHAIN_DIR>\bin`
50    - For example: `C:\DevTools\riscv32-gnu-toolchain\bin`
51- Step 4: Prepare [OpenOCD](https://github.com/hpmicro/rtt-debugger-support-package/archive/v0.4.0.zip)
52  - Download and extract it to specified directory, for example: `C:\DevTools\openocd-hpmicro`
53  - Add `OpenOCD` environment variable `OPENOCD_HPMICRO` to `<OPENOCD_HPMICRO_DIR>\bin`
54    - For example: `C:\DevTools\openocd-hpmicro\bin`
55
56#### Configure and Build project
57
58Open RT-Thread ENV command-line, and change directory to this BSP directory, then users can:
59
60- Configure the project via `menuconfig` in `RT-Thread ENV`
61- Build the project using `scons -jN`, `N` equals to the number of CPU cores
62- Clean the project using `scons -c`
63
64#### Hardware Connection
65
66- Switch BOOT pin to 2'b00
67- Connect the `PWR_DEBUG` port to PC via TYPE-C cable
68
69
70#### Dowload / Debug
71
72- Users can download the project via the below command:
73  ```console
74  %OPENOCD_HPMICRO%\openocd.exe -f boards\debug_scripts\probes\ft2232.cfg -f boards\debug_scripts\soc\hpm5300.cfg -f boards\debug_scripts\boards\hpm5300evk.cfg -c "init; halt; flash write_image erase rtthread.elf; reset; shutdown"
75  ```
76
77- Users can debug the project via the below command:
78
79  - Connect debugger via `OpenOCD`:
80
81```console
82%OPENOCD_HPMICRO%\openocd.exe -f boards\debug_scripts\probes\ft2232.cfg -f boards\debug_scripts\soc\hpm5300.cfg -f boards\debug_scripts\boards\hpm5300evk.cfg
83```
84  - Start Debugger via `GDB`:
85
86```console
87%RTT_EXEC_PATH%\riscv32-unknown-elf-gdb.exe rtthread.elf
88```
89  - In the `gdb shell`, type the following commands:
90
91```console
92load
93c
94```
95
96### **Running Results**
97
98Once the project is successfully downloaded, the system runs automatically. The LED on the board will flash periodically.
99
100Connect the serial port of the board to the PC, communicate with it via a serial terminal tool(115200-8-1-N). Reset the board and the startup information of RT-Thread will be observed:
