#Updates This toolchain is not current for Spring 2013. I am LAing this term, and will likely update this. Keep in mind that this toolchain is not officially supported or endorsed by the 6.115 staff. I might be able to help, but no promises.

Check back for updates.

I recently added code from Isaac Evan's preprocessor. To get the update, do a normal pull

git pull

Followed by

git submodule init
git submodule update

This wil get you all the sweet features.

If the pull complains about changes to Makefile, come bother me, or read about git. Sorry, I don't have time to write too much.

#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]

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).

I will likely continue to work on the toolchain, and will send out an email if I add something notable. prog8051 is a bit sketchy. I haven't tested it much. I will add version numbers to my toolchain if I release more than a few versions.

A usb-serial dongle that works on Linux is: http://www.amazon.com/TRENDnet-Serial-Converter-TU-S9-White/dp/B0007T27H8/ref=sr_1_1?ie=UTF8&qid=1328853484&sr=8-1 #Ubuntu Instructions

sudo apt-get install dosbox python-serial python-argparse
cd ~
git clone git://github.com/igutekunst/6.115-Toolchain.git 6.115
echo  "export PATH=~/6.115/tools/bin:\$PATH" >> ~/.bashrc
source ~/.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

-rw-r--r--  1 isaac   44 Feb  9 17:55 test.obj

Additionally, you can type

make program

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

ls /dev/tty*

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

##prog8051 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 prog8051myfile.obj --serial-port /dev/thecorrectserialport

For example,

prog8051  myfile.obj --serial-port /dev/ttyUSB0

To see the prog8051 syntax, type

prog8051 --help 

If you want to avoid typing the serial port each time, edit the file prog8051_config.ini in the 6.115 directory to reflect the correct port.

#Mac Instructions

• 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 ~/6.115/tools/bin/dosbox 

• Follow the general instructions above, but Instead install pyserial, and argparse with the following command

sudo easy_install pyserial
sudo easy_install argparase

##Problems If you get something like

isaac$:~/6.115$ rasm test.asm
Executing DOSBox...
Sorry, DOSBox failed.  Full output follows:
DOSBox version 0.74

isaac$:~/6.115$

You should modify tools/bin/rasm and adjust the indicated line to point at the rasm directory.

#Getting Involved / I fixed something

If you find something broken, or want to improve the toolchain, go ahead and fork it on GitHub. If you don't want to learn git, just send me a modified file, and I'll merge it if it looks ok.

I can also make you a collaborator on GitHub if you are intersted enough.
