Build Project:
|
|
|
|
|
==============
|
|
|
|
|
there are two ways to build the renesase M16C project:
|
|
|
|
|
1, install IAR Embedded Workbench for renesas m16c(recommend EWM16C-EV-3501.exe)
|
|
|
|
|
Open Workspace rtt2m16c.eww by IAR directly
|
|
|
|
|
rebuild all
|
|
|
|
|
the target file(rtt2m16c.mot) will be produced in /rt-thread/bsp/m16c62p/Debug/Exe
|
|
|
|
|
you can download the rtt2m16c.mot to m16c board with E8A
|
|
|
|
|
|
|
|
|
|
2, install python, scons and IAR for m16c(recommend python2.7, scons1.3.1 and EWM16C-EV-3501.exe)
|
|
|
|
|
open a windows cmd, and change directory to m16c project, like /rt-thread/bsp/m16c62p/
|
|
|
|
|
#set PATH=C:\Python27\Scripts;%PATH%
|
|
|
|
|
#scons -c
|
|
|
|
|
#scons -j 2
|
|
|
|
|
|
|
|
|
|
3, crate IAR project with template project
|
|
|
|
|
#set PATH=C:\Python27\Scripts;%PATH%
|
|
|
|
|
#scons --target=iar -s
|
|
|
|
|
add the context_iar.asm to M16C62P, and remove the context_iar.S
|
