Welcome

This is TOPPERS/SSP for ARMv6-M architecture processors, a kind of Real-time OS kernel.

About TOPPERS, please see http://www.toppers.jp/en/index.html.

About TOPPERS/SSP kernel, please see http://www.toppers.jp/ssp-kernel.html(in Japanese).

Supported Target boards:

• LPC812-LPCXpresso Board (Cortex-M0+)

• LPC1114-LPCXpresso Board (Cortex-M0, Switch branch to "features/lpcxpresso_lpc1114_gcc" is needed)

How to use (example for Mac OS X)

1. Get source code.

   $ git clone https://NSaitoNmiri@bitbucket.org/NSaitoNmiri/toppers_ssp_lpc812.git
   

2. Get TOPPERS configuration software

   To build the SSP kernel, get source code for the Configurator software, which is necessary to use the SSP, can be downloaded here ( written in Japanese).

   Setup procedure example of the configurator (boost library is needed for build the configurator software):

   $ ls
   toppers_ssp_lpc812
   $ wget http://www.toppers.jp/download.cgi/cfg-1.8.0.tar.gz
   $ ls
   toppers_ssp_lpc812
   cfg-1.8.0.tar.gz
   $ tar xvf cfg-1.8.0.tar.gz
   x ./cfg/cfg.sln
   x ./cfg/configure
   (snip..)
   x ./cfg/toppers/itronx/static_api.hpp
   x ./cfg/toppers/itronx/static_api_parser.hpp
   $ cd cfg
   $ ./configure
   LIBBOOST_SUFFIX=-mt
   BOOST_VERSION=1_55
   BOOST_DIR=/usr/local/include
   LIBBOOST_DIR=/usr/local/lib
   OPTIONS=
   $ make
   make BOOST_DIR="/usr/local/include" LIBBOOST_SUFFIX="-mt" CXXFLAGS="-O2 " -C toppers
   c++ -O2   -I/usr/local/include -I..  -c -o builtin_function.o builtin_function.cpp
   (snip..)
   c++ -O2  -o cfg cfg.o cfg0.o cfg1.o cfg2.o cfg3.o cfg4.o cfg_version.o -L/usr/local/lib ../toppers/itronx/libitronx.a ../toppers/libtoppers.a   -lboost_system-mt -lboost_filesystem-mt -lboost_program_options-mt
   $ cd ../toppers_ssp_lpc812/ssp_kernel/
   $ ln -s ../../cfg cfg
   

3. Import project directory in LPCXpresso IDE.

   • Launch 'lpcxpresso' application.

     

   • In 'File' menu, select 'Import...'.

     

   • In 'Import' dialog window, select 'Existing Projects into Workspace' in 'General' category.

     

   • In 'Import' dialog window, select 'browse' button besides 'Select root directory:' label.

     

   • In file selection dialog, select the source code directory cloned and 'open' button.

     

   • After file selection, push 'Finish' button.

     

   • Import finished.

     

4. Compile sources and build a executable file with LPCXpresso IDE (filename: ssp).

   • In 'Project' menu, select 'Build All'

     

     If kernel build is completed successfully, the file named 'ssp' will be generated.

5. Connect LPC812-LPCXpresso Board to PC via USB.

   • Sample application of SSP uses one UART port. Thus, RS232 or UART-USB module is needed.

     • UART is 3.3v
     • The pins used are GND, P0_0(RX), P0_4(TX)
     • UART setting: 19200bps, 8bit, 1stop, parity-none, no-flow (for LPC1114, 115200bps)

     

6. Download the executable file to a target board (LPC812 board).

   • In LPCXpresso IDE, select 'Debug' perspective.

     

   • In LPCXpresso IDE, press 'Debug' button. Then, downloading is started and software execution is stopped before 'target_initialize' function call in 'sta_ker' function.

     

   • In LPCXpresso IDE, press 'Resume' button. Then, execution is started.

     

Have fun!
