I recently learned how to burn the bootloader onto the atmega 1284p chip used by Sanguinololu. Followed a great tutorial on letsmakerobots.com to upload using Arduino 1.0.4 through an Arduino nano. May want to give it a try if you get stuck. I'm a newb at this and it worked well..

I had the same issue with my SD2.
Ordered a AVR mega644PA with installed bootloader off eBay for 9.00 + 4.00 shipping.

Swapped the chips out and loaded the firmware, no problems at all. Can now update as described in the various instructions out there.

When you connect up to R-H is there a few seconds before it connects or does it connect instantly?

Almost - right now I think my 644p is missing the bootloader since I can get everything to compile correctly but I'm having a really tough time sending it without getting errors like"avrdude: stk500_getsync(): not in sync: resp=0x89" which I've found plenty of pages on. I've tried the different baud rates and the different reset button timings and I do have a jumper re:Sang1.3a....

Suggestions besides setting up to burn the bootloader? -will be waiting on parts for at least a week.

So you clearly understand that I too once knew very little about this stuff
So did you get all of your questions figured out?

Mostly with the Sang is make sure you save the changes you made in configuration.h
Then you can disregard pretty much all of the above instructions just click UPLOAD while hitting the reset button.
It's that simple.

Would this be the case for the original bootloader too or does that need to be updated?

Can you please clarify (ELI5) what you mean by "clicking upload while hitting the reset button?

[I also have an old Sang 1.3 with the original (which?) bootloader]

EDIT - found the clarification I was asking about: http://www.soliforum.com/post/30331/#p30331

That would be my bad (Picture would have helped earlier)
I should learn not to assume these things.
The Sang boards are easy and if you'd like just PM me and I can take you through it.

Sketch FINALLY loaded successfully with the right board selected (after finding the Sanguino files). But the max temp didn't change. It still shuts off at 225C even though I changed the definition to 330C.

I think I'm just gonna put this thing (E3D) in the oven to heat it to 300. All this is just so I can tighten this thing another 1/16th of a turn! Sigh.

Who's still got one and can help out with the procedure?

Aha.

So I found the hex I need. Now I just gotta get it on the board. And the best way to do that is?

BTW, is that good or bad?

Okay, it's just one thing after another here. I think the reason I couldn't see the boot pins is because there was a jumper already on them. So after a reboot, I continued with the instructions posted above.

But NOW I'm stuck on this. It asks me to hit the reset button. I can push it til my finger falls off and it's not gonna do anything.

Next idea? TIA

I got everything downloaded fine. Thanks guys.

But now this is where I get stuck.

26. Add a jumper to the BOOT pins on the printboard (back of the printer) or bend the 2 pins so they are touching , then press the RESET button

I can only find the serial pins on the board. I don't see any boot pins or pads. Am I just blind? Or do I use two of the serial pins?

You need the BootloaderHID I'm on my phone so your going to have to search that out.
As far as the updated firmware you don't have to do that part but you should. The link for that doesn't work because it has been updated since that post. Just download Adrian's latest from github.
Hope that helps
