These instructions have been tested on Mac and Ubuntu (donlanes). You will need some kind of a serial port to them to work. If you have questions, please ask me (isaac).
A few notes
this is running the real 16bit DOS rasm executable inside of DOSBox. This means DOS limitations apply. Make your filenames really short (8 characters or less). To read more about the restrictions, visit http://en.wikipedia.org/wiki/8.3_filename
sudo apt-get install dosbox python-serial mkdir ~/6.115 cd ~/6.115 wget http://mit.edu/~igutek/Public/6.115_toolchain.zip unzip 6.115_toolchain.zip echo "export PATH=~/6.115/tools/bin:\$PATH" >> ~/.bashrc
Test this by typing rasm test.asm
It should print something like this:
Executing DOSBox... Rasm51E 1.32 (c) Rigel Corporation 1990-1995 Assembling file t:temp.asm opening file t:temp.asm pass 1 4 lines of source code read pass 2 assembly time : 0.000 seconds writing file t:temp.lst to disk writing file t:temp.obj to disk disk write time : 0.000 seconds no errors found...Rasm51E terminates... -rw-r--r-- 1 isaac 26 Feb 9 17:55 test.err -rw-r--r-- 1 isaac 132 Feb 9 17:55 test.lst -rw-r--r-- 1 isaac 44 Feb 9 17:55 test.obj
Additionally, you can type
To upload the program on the RJ31P (is that what it's called).
Serial Port Settings
For this to work, edit the Makefile and change the serial port to be the correct one for you machine. To find out, first type
Now plug in your serial port, and repeat the command. The item that shows up is the serial port.
Modifying the Makefile for your own code
You can modify the Makefile to change which asm file it assembles by changing the SRC variable.
Just open the file and replace SRC := test with SRC := myfile (without the asm). Your file must be named myfile.asm
Plain Old rasm
If you want, you can also just use rasm as documented in the lab
If have also included a program I wrote, prog8051 which will upload an .obj file the the board if it is in monitor mode. To use it, type prog8051 -o myfile.obj --serial-port /dev/thecorrectserialport
to see the syntax.
You can edit prog8051_config.ini and change the default serial port that prog8051 uses. This way you can program simply by typing
prog8051 -o myfile.obj
- Copy DOSBox.app into /Applications
- Make a symlink to /Applications/DOSBox.app/Contents/MacOS/DOSBox from ~/6.115/tools/bin/dosbox
ln -s /Applications/DOSBox.app/Contents/MacOS/DOSBox ~/Dropbox/Classes/6.115/tools/bin/dosbox
- Follow the general instructions above, but Instead install pyserial with the following command
sudo easy_install pyserial
