Just a thought for you to contemplate until Riley or Alden pop in.

In fixing something in the most recent build of tgFX, Riley had to change flow control to RTS/CTS, away from Xon/Xoff. Since your problem sounds like buffer over run, perhaps you can experiment on that path?
That would be $ex=2.
Good luck

This is total speculation on my part – perhaps avrdude on windows expects a .txt file for it’s hex to binary processing to work properly?
I left Windows a long time ago for Linux and have forgotten some of the unusual rules regarding handling binary files.

Anyway, sounds like you are up and running.

Might I suggest to check around for CoolTerm – it seems to be a popular low level interface useful for communicating with a TinyG.
I use Putty myself, primarily because it is available Linux and Windows.

As for tinyG, review this thread

https://www.synthetos.com/topics/new-tgfx-pushed/

I am seeing some good results with this latest EDGE (== beta) version that Riley is working on.

Thanks for the check out, I am now having fairly consistent good success running Prevues with TinyG 0.96/380.08 and tgFX EDGE 2404 as well.

Here are the current parameters I am using

Here are the results

Riley thinks he knows where the intermittent lead-in bug is, otherwise looks very good.

IMHO, your P4 may not be enough horsepower to run this java app. Can you try it with a P5 or higher to test your setup?

Try to grab the file from my dropbox

https://dl.dropboxusercontent.com/u/50261731/tinyg.hex

The size should be close to 282.2 KB, may not be exact because of differences between Linux and Windows interpretation of “K”.

If , in running avrdude, you see

avrdude: writing flash (102724 bytes):

you will probably be good.

Good Luck

Just reread your post – 283K is probably the right Windows size.
You could read it, so it is probably ASCII.
My guess is that avrdude does the ASCII–>Hex conversion before sending to the bootloader

OK, now I see the error in my ways.

In Linux, the easiest way to get such a file is the cli command
wget https://raw.github.com/synthetos/TinyG/master/firmware/tinyg/default/tinyg.hex
Probably same in IOS, sorry, not sure for Windows.

Big day: Ready to connect my ShapeOko

Well, that’s too bad.
I downloaded that TinyG.hex file to my Linux system, then ran avrdude 5.11.1. My results are the same areinike, a flashing brick.

It would be helpful if Alden could post what version number avrdude the downloader was tested against, since there is not a clear answer as to which version of avrdude is made available with the arduino (referenced on the wiki)

The good news is I still have your address in my Priority Mail address book, you will be seeing my TinyG V7 soon for reprogramming, I don’t have a programmer.

Can you try to run a Prevue (Motors inhibited) of the ShapeOko hello-world Gcode found at

https://dl.dropboxusercontent.com/u/50261731/Hello_World_ShapeOko.txt

I have been having issues (distorted characters) with it, and I wonder if your configuration parameter set is better than mine.

If it works, can you post your current $$ dump?

Thanks
