LPC55S69-EVK BSP Introduction

English | 中文

1. Introduction

The LPC55S69 is a high-performance microcontroller based on the Cortex-M33 core from NXP Semiconductors. Includes the following hardware features:

HARDWARE	DESCRIPTION
Chip model	LPC556x/LPC55S6x Full range
CPU	Cortex-M33 Dual Core, with FPU
Frequency	150MHz
Basic peripherals	8 x Flexcomm (optionally configured as USART/SPI/I2C/I2S) / 1 x 50MHz SPI / Dual USB (1 H and 1 Full, Master-Slave Support)
Characteristic	PowerQuad DSP coprocessor/security peripheral: PRINCE/PUF/CASPER/AES-256/HASH

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

    git clone https://github.com/RT-Thread/rt-thread.git

2. Configure the project and prepare the ENV

（Linux/Mac）

    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）

    scons --menuconfig

（Windows(use ENV)）

    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）

    SET RTT_CC=iar
    scons --target=iar -s

（Windows MDK5）*

    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

Some error messages are as follows:

Or you can choose to refer to this forum post:AC6 compiler error unsupported option '--c99' solution

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

    SET RTT_EXEC_PATH=[GCC path]

（Linux/Mac arm-none-eabi-gcc） Use the following command to set the GCC path

    export RTT_EXEC_PATH=[GCC path]

Compile（WindowsLinux/Mac arm-none-eabi-gcc）

    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

    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*:
