I came back with new article about porting ECOS (Redboot) into Aki-H8 Ethernet board that I just bought from Akihabara last week.I tried to push ECOS in to this for 3 days and now it was success. The next phase, I hope to porting Linux kernel into it too.Please waiting for that.(*_*)/" Before cooking Ok.First of all. We need some ingredients for making this project work. Here is a list - Hardware PC : my PC is desknote VIA cpu 500 MHz RAM 256MByte Window 2000 --little bit slow. Board : Aki-H8/3069 Ethernet board (with/ without base board) RS-232C cable for connect PC and board. - Software Cygwin : with gcc and other necessary program installed. binutils-2.13.2 : Binary utilities for cross-compile h8300-elf-tools.cygwin.tar.tar : This is ready compiled cross compiler (h8300-elf) you can download this packet from http://strawberry-linux.com or if you want to compile all package by yourself.Just download gcc from GNU website. ECOS and ECOS-H8 package : Just download from http://strawberry-linux.com Making time First of all, We need to extract h8300-elf-tools.cygwin.tar.tar package and move it to home directory of your Cygwin.Then just set the PATH global variable to point at your cross compiler directory by using this command... export PATH=$HOME/h8_elf/bin:$PATH O.K at this phase. I try to compile ecos but the result was h8-elf-ld linker command can't fine necessary library.So,I have to build Binary utilities again. By extract binutils-2.13.2 package and then patching it .After that just make a cross compiler with ... ./configure --target=h8300-elf --prefix=$HOME/h8_elf make ; make install Just wait for a while. Then we ready to compile ECOS for H8. First, download latest ECOS and place it in build directory.Next replace files with ECOS-H8 package.This will give you more option to compile ECOS with H8 board. After that just call ECOS configuration tool from tool directory. With this GUI just seleft package of Aki-H8/3068 Ethernet board and Redboot package option. Then save a project and start to build a library. If everything is right . You will got redboot.bin in you project install directory. now convert it to motorola hex file format with ... h8300-elf-objcopy -I binary redboot.bin -O symbolsrec redboot.mot Now we ready to rumble. Just burning this file in to the board with h8write program that coming when you buy it. (set your jumper and connect via RS-232 cable first) h8write -3069 -f20 redboot.mot OK. now connect the board with PC . Set jumper to running flash rom.Open you ternimal and set it to .... Port ：COM1 Just reset the board and then you will see greeting message from Reboot. Now please enjoy your H8 ECOS !!!  |
