H8S/2329 Sample Project with GNU Compiler   If you don't want to use the big HEW (High-Performance Embedded Workshop) from Renesas to develop your H8S/2329 software, there is an easy way with a simple text editor, the freely available GNU-C Compiler and the FDT (Flash-Development-Toolkit) from Renesas. Now i describe how to bring it to work.   I recommend to download these tools:   Tool Description Download Hint SciTE Texteditor with syntax highliting http://www.scintilla.org/SciTEDownload.html FDT Flash Development Toolkit from Renesas http://www.kpitgnutools.com/renesasTools.php FDT is included in HEW GNUH8 GNU Tools for Renesas H8 Microcontrollers http://www.kpitgnutools.com COFF Version   Example Project Description SampleProject Interrupt driven counter with output on LED's SampleProjectDisplay Same as above but with LCD-Display support   What you have to do: Install SciTE Install FDT (or install whole HEW) Install the GNUH8 Toolchain Copy or move the folder "GNUH8v0304-COFF" (or "GNUH8-COFF" when installed on top of HEW) from the installed GNU-Tools to "c:" Copy it only when you also want to use HEW, else move it. Let the path point to the GNU-Tools (Other Utilities) or simply copy "make.exe", "msys-1.0.dll" and "sh.exe" from "Other Utilities" to c:\windows or c:\winnt\system32 Extract the SampleProject to a folder of your choice Open the file "main.c" in SciTE Press F7 to build the SampleProject, now you should have a new .mot file If it doesn't compile, check the first line in the makefile in your project-directory. It must point to the GNU-Tools (h8300-coff-gcc, h8300-coff-as...) Run FDT and create a new Project Import our MOT-File we want bo be flashed Create the device image On your 2329-Board, set the switch to "Boot" and after that press the reset button Flash :-) Set the switch to "User" and press reset to start the flashed program Optionaly press Alt-C in FDT to disconnect from 2329
