Everything I've read talks about removing the ATMega chip and wiring it to a breadboard, then loading the bootloader. I'm guessing that means I can't load it while it's on the Sanguinlolou board. Please forgive the dumb questions.. like I said.. i'm new to this.

Re: Verifying bootloader and/or firmware on Sanguinololou with ATMega1284P
You can install a boot-loader fine while its on the SL board, Ive done this more times than I care to count... Just wire in the isp header pins and use those with a avrisp. (these pins are often missing on cheap boards)
Main issue is the "fuses" make sure you get those correct. (SL has a resonator vs a crystal, requires different fuse settings)
You borads.txt contains what fuse setting the arduino ide will set. (Fuses are set when you upload a boot loader from within the arduinio ide) A generic 644p or 1284p chip profile will presume a Crystal.
Second potential issue is that some of the really cheap avrisps do not support chips with large firmwares, ie they do not support 644p or 1284p

Any help or resources you could share would be greatly appreciated. I'd LOVE to get this thing working! Even if you've got time to PM or even call.

Re: Verifying bootloader and/or firmware on Sanguinololou with ATMega1284P
Its different depends on what programmer you have, and what chip you have (644p or 1284p)
but take a look at my old notes [dustsreprap.blogspot.co.nz] and [dustsreprap.blogspot.co.nz] some 1284p notes [dustsreprap.blogspot.co.nz] and Finally best way to add Sl support into the current arduino IDE [dustsreprap.blogspot.co.nz]

normally it would be like

If your lucky they have just move the 4 pins over so the last 6 pins are what you need..
Your going to have to trace the board or find the manufacturers documentation
I think what they have done is added the glcd converter on board

Re: Verifying bootloader and/or firmware on Sanguinololou with ATMega1284P
no, I’ve never seen that board before. They have changed it without document it
Where did you get this board? got a url? maybe there is some documentation there.

I am having the same issue with my Melzi board. I uploaded the bootloader and still the same issue. I might try an older version of the Arduino IDE

Dust,
If I'm understanding your notes correctly, if I connect an LED (BTW, the link in your notes is no longer valid) to the last pins, and I get the 3 pulses, I have a bootloader? I can attach a pic of my Sanguinololou board it it'll help.

Re: Verifying bootloader and/or firmware on Sanguinololou with ATMega1284P
Only if you have a Sanguinololou, and you also need a resistor to limit the current (1K ish), and the led has to be around the correct way.
This shows the correct way around (on a standard ardunio) You just need to identify which is ground and which in a IO line on the pololu module
![arduino-led-tcp-sketch.png]( "arduino-led-tcp-sketch.png")
![0J3360.600.png]( "0J3360.600.png")
Most boot loaders flash this IO line, but its not guaranteed.
The only way to be sure you have a boot loader installed, is to install one yourself.

I've been able to get mine working. The problem was the com port driver. The one that comes with windows didn't seem to work. Downloaded the vcp driver from ftdi

Help with Firmware upload
Hi!
I have a problem with my Sanguinololu 1.3a
I recently wanted to upload to it Marlin firmware, because I had to install new ATMEGA1284P-PU microcontroller, but in Arduino 0023 I keep getting "avrdude: stk500_getsync(): not in sync: resp=0x00" error after trying to upload.
I tried ways described in [reprap.org] article:
I tried that 10 seconds reset holding.
I already had those 2-pin connected before.
I can see USB Serial Port (COM3) under Ports (COM and LPT).
I have RTS on close checked.
Anyone have any suggestion on what I am doing wrong?

Re: Help with Firmware upload
Are you sure that the new ATMEGA1284 has a bootloader installed?

Re: Help with Firmware upload
No, I'm not.
I have a usbasp programmer (or whatever that is called), because I had to burn bootloader to the previous too.
But I don't remember how to...
I know how to connect it to the board, bot I don't remember what I should select inside Arduino and I don't want to try and error this problem out.

Re: Help with Firmware upload
In the Arduino IDE just select the right board (Sanguino ATMega1284p 16MHz), the right programmer (USBasp if it's that what you have) and the port of you programmer, and then click "Burn Bootloader". Check also the wiki.
Regarding "...usbasp programmer (or whatever that is called)", just beware in case it is not an USBasp but a USBtinyISP, since this does not work with the 1284p.

Melzi lost USB connection
Hi all.
During printing the other day I had my Prusa clone jamb to the extent that it tripped the house mains supply.
On powering up again every thing works except there is no communication via USB. My Laptop doesn't respond (no comport recognition). I have changed the cable. Checked the Laptop is OK by using my other machine.
I have control of the printer via the LCD controls and can print from SD.
Its a Melzi V2.0 board running repetier firmware. Any ideas where it is broken? and how to fix?
I can't find any reference to this failure on the web. I think there is only the connector, TTL (is that the protocol ?) chip and a couple of capacitors before it goes into the processor.
If its the chip can I buy a USB to TTL lead and solder it in place of the on board chip?
Tonight i will check if the processor powers up when the jumper is set to USB 5V to see if the 5V is there. My probes on my MM are a bit to big to measure it off the connector and board.
