- Install SCons.
Ubuntu, Debian:$ sudo apt-get install scons
RPM-based (Red Hat, SUSE, Fedora ...):$ sudo yum install scons
- Install the gcc toolchain like: gcc-arm-none-eabi-9-2019-q4-major
- Clone this project.
$ git clone https://github.com/NXPmicro/sfw.git
- Enter the evkmimxrt1170 directory.
$ cd target/evkmimxrt1170/
- Config the evkmimxrt1170 project.
$ scons --menuconfig
- Set 'EXEC_PATH' as gcc toolchain install path for
CROSS_TOOL == 'gcc'
insfwprofile.py
.
Below is an example:
EXEC_PATH = r'/opt/share/toolchain/gcc-arm-none-eabi-9-2019-q4-major/bin'
Alternatively, 'SFW_EXEC_PATH' can be added into Linux environment variable to cover the 'EXEC_PATH'. - Build the image with gcc toolchain.
$ scons
thensfw.bin
image is built insfw/target/evkmimxrt1170/build
directory. - Download the image.
Use DapLink drag-n-drop or other tools to download image.
- Clone this project.
git clone https://github.com/NXPmicro/sfw.git
- Enter the directory
sfw/target/evkmimxrt1170
. - Double click the batch file
env.bat
. - Config the evkmimxrt1170 project.
scons --menuconfig
- Build and download the image.
- with gcc toolchain
(1) Obtain gcc toolchain from ARM or MinGW website and install to the Windows host.
(2) Set 'EXEC_PATH' as gcc toolchain install path forCROSS_TOOL == 'gcc'
insfwprofile.py
.
Below is an example:
EXEC_PATH = r'C:\Program Files (x86)\GNU Arm Embedded Toolchain\9 2020-q2-update\bin'
Alternatively, 'SFW_EXEC_PATH' can be added into Windows environment variable to cover the 'EXEC_PATH'.
