1  Using Arduino / Installation & Troubleshooting / Re: Mega 2560 refuses to respond - bootloader problem? on: April 01, 2014, 02:14:29 pm
I am just saying the ICSP near the usb port is for the 8u2/16u2 and the other one is for the mega2560. The bootloader goes into the 2nd one. The first one: http://arduino.cc/en/Hacking/DFUProgramming8U2

To fix mine, I use avrdudess and that cheap avrasp, first plugging it into:

Without connecting the usb or power (only the power provided by avrasp)

Then:


(This is if the serial port isn't  working properly)

Later on, if the serial port is present but I can't send a Sketch, use this other connector with the avrasp:


Now:


Wait 1-2  mins and the board starts to blink and everything is ready.

Remember that the mega has 2 programmable chips, there are 2 connections, the one near the mega2560 is the one where you upload the bootloader, the other needs the serial+dfu firmware

If you can switch to DFU, the chip is still alive so that's good. If not, the programmer (you can use another arduino too, the cheap programmer is just a convenience) can load the fw with dfu and serial again, if the chip is alive.

If you need the programmer for less than $3 hahah:

Have you tried this: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS034089

After installing, probably the driver is in c:\windows\inf (sort by last created/modified)

I haven't tried but I have used that way to install some old drivers. I don't think it is a hardware limitation, it might be something like chineses cloned that chip too much that prolific stopped supporting these old versions or something like that.

I can't say, I have a similar setup running for years now (old makerbot with mega2560). If is not detected by the pc (trying other usb cables/ports) in any mean, that can be a dead 8u2 or 16u2 (the small one near the usb).

Does that happens with: http://forum.arduino.cc/index.php?topic=118440.0 ?

I think official arduino switched from the previous buggy RXTX to a newer library. My mod uses the buggy RXTX but "fixed": http://forum.arduino.cc/index.php?topic=46977.0

Have you tried with the win7 driver doing this: http://dhakshinamoorthy.wordpress.com/2012/05/14/installing-an-unsigned-driver-in-windows-8-x64/ ?
10  Using Arduino / Installation & Troubleshooting / Re: Mega 2560 refuses to respond - bootloader problem? on: March 27, 2014, 03:36:39 pm
It is a genuine mega? I had a lot of bad experiences with chinese ones, very unreliable. The way I get these cheap ones to work is flashing the bootloader on the 8u2 and atmega (using a $3 usd avr programmer from ebay and the 2 2x3 pins connectors) and then loading the sketch. It works properly for a few loads.

With the 1280 and 2560 genuine ones I never had any problem. But the price difference is massive so for a semi-permanent setup I just test in the genuine and then use the clone for the final upload.

This mod slows that down: http://forum.arduino.cc/index.php?topic=118440.0 (but it is v1.0.5 not v1.5.x)

You need to ask the MiiCraft guys for the original source code to reupload it again in the same way you uploaded the empty code.

BTW, how much is that printer?

Yeah, this might be related with https://github.com/eried/Arduino/issues/13

But, I have an Leonardo now to test now smiley

Thanks a lot smiley I just added that code from a forgotten suggestion to the official one smiley-grin but certainly I will update that.

Sure https://github.com/eried/Arduino/

I integrated Teensy on november last year, it works nice, I haven't tested it a lot but I am just waiting for a next arduino minor release.
