|
||
**English** | [中文](README_zh.md)
|
||
|
||
## 1. Introduction
|
||
|
||
The LPC55S69 is a high-performance microcontroller based on the Cortex-M33 core from NXP Semiconductors.
|
||
Includes the following hardware features:
|
||
|
||

|
||
|
||
## 2. Hardware development system
|
||
|
||
|
||
|
||
|
||
|
||
## 3. Quickly Get Started
|
||
|
||
|
||
| ENVIRONMENT | DESCRIPTION |
|
||
| ------------------- | ------------------------------------------------------------ |
|
||
| PC Operating System | Linux/MacOS/Windows |
|
||
| Compiler | arm-none-eabi-gcc version 6.3.1 20170620 (release)/armcc/iar |
|
||
| Build tools | scons/mdk5/iar |
|
||
| Depends | Env tool/(MDK or IAR or arm-none-eabi-gcc)/git/debugger driver |
|
||
|
||
1) Download the source code
|
||
|
||
```bash
|
||
git clone https://github.com/RT-Thread/rt-thread.git
|
||
```
|
||
|
||
2) Configure the project and prepare the ENV
|
||
|
||
（Linux/Mac）
|
||
|
||
```bash
|
||
cd rt-thread/bsp/lpc55s69_evk
|
||
scons --menuconfig
|
||
source ~/.env/env.sh
|
||
pkgs --upgrade
|
||
```
|
||
|
||
（Windows）
|
||
|
||
>Download the ENV toolkit [RT-Thread][1]
|
||
|
||
3) Configure the chip model
|
||
|
||
（Linux/Mac）
|
||
|
||
```bash
|
||
scons --menuconfig
|
||
```
|
||
|
||
（Windows(use ENV)）
|
||
|
||
```bash
|
||
menuconfig
|
||
```
|
||
|
||
On the menuconfig page, configure and select the corresponding chip model, if the development environment is MDK/IAR, you need to generate the project.
|
||
|
||
4) Build Project (please skip this step under Mac/Linux)
|
||
|
||
（Windows IAR）
|
||
|
||
```bash
|
||
SET RTT_CC=iar
|
||
scons --target=iar -s
|
||
```
|
||
|
||
（Windows MDK5）*
|
||
|
||
```bash
|
||
scons --target=mdk5 -s
|
||
```
|
||
|
||
*This board support package does not support projects that generate MDK4
|
||
|
||
**MDK and IAR must manually select the chip signal once in the project after the project is built, otherwise a serious compilation error will be generated.**
|
||
|
||

|
||
|
||
Note: Because some versions of Keil5 have issues with AC6 compiler support, it is recommended to upgrade keil to the latest version
|
||
|
||
> [Download the latest version of Keil here](https://www.keil.com/update/check.asp?P=MDK&V=5.38.0.0&S=)
|
||
|
||
Some error messages are as follows:
|
||
|
||
|
||
|
||
Or you can choose to refer to this forum post:[AC6 compiler error unsupported option '--c99' solution](https://club.rt-thread.org/ask/question/4c744e41ded5efb0.html)
|
||
|
||

|
||
|
||
5) Compile
|
||
|
||
To use the MDK or IAR, see the corresponding tutorial
|
||
|
||
（Windows arm-none-eabi-gcc）
|
||
Use the following command to set the GCC path
|
||
|
||
```bash
|
||
SET RTT_EXEC_PATH=[GCC path]
|
||
```
|
||
|
||
（Linux/Mac arm-none-eabi-gcc）
|
||
Use the following command to set the GCC path
|
||
|
||
```bash
|
||
export RTT_EXEC_PATH=[GCC path]
|
||
```
|
||
|
||
Compile（WindowsLinux/Mac arm-none-eabi-gcc）
|
||
|
||
```bash
|
||
scons -j4
|
||
```
|
||
|
||
Or use the `scons --exec-path="GCC toolchain path"`command to compile directly while specifying the toolchain location.
|
||
|
||
The following message indicates that the compilation was successful
|
||
|
||
```bash
|
||
LINK rtthread-lpc55s69.elf
|
||
arm-none-eabi-objcopy -O binary rtthread-lpc55s6x.elf rtthread.bin
|
||
arm-none-eabi-size rtthread-lpc55s69.elf
|
||
text data bss dec hex filename
|
||
41596 356 1456 43408 a990 rtthread-lpc55s6x.elf
|
||
scons: done building targets.
|
||
```
|
||
|
||
|
||
If compiled correctly, the rtthread-lpc55s6x.elf, rtthread.bin file will be generated. where rtthread .bin binary firmware
|
||
|
||
## 3. Download and Execution
|
||
|
||
Programming can use emulators, ISPs, and other ways to repeat them here.
|
||
|
||
### 3.1 Running Results
|
||
|
||
If the compilation & programming is correct, you will see the RT-Thread startup logo information on the Flexcomm0 serial port*:
