[Random Dude]

I just rigged up a breakout box for the serial and connected in a second comm port (Rx only) to either the Tx or the Rx lines from the computer to the Edu.

I did find that the IFI is basically identical to the Microchip spec. Two notable exceptions:
-There are two undocumented commands, however each is only used once, and the data they send doesn't appear to change.
-I have found what may be a bug in the code as well. I'm going to test more and confirm it.


Hopefully Sean will come link to the real microchip bootloader (since I can't seem to find it). If not I might just start working on coding it myself.


[Edit] I've determined that that first commands is a bulk erase command, while the second command starts the user code running.
And the "bug" was my fault.


[EDIT 2] Found the Microchip loader. The reason for the file size differences is that the DLL was built with the debug code still in.
Without debug code the DLL is only 32k, which means FIRST added stuff to it.

The loader does appear to work, however the microchip programmer doesn't restart the user code automatically as does the IFI programmer. (minor point)

Anyway, I'll clean up all my notes and put them in a organized fashion and post it here in the next day or so. That way anyone who feels motivated to port the IFI loader to linux, Mac, PDA's, etc can. (And hopefully they will share)

This post is now officially too long...
