ATMEL Mega1284P evaluation board avalible

Are there any links in web or is it closed source? |Thanks

Links for the Bobuino?
There are these 2
http://www.crossroadsfencing.com/BobuinoRev17/

The schematics & board layout have been posted in this thread several times as I worked stuff out.

I read whole thread, so much info to consume. Anyway I see you have used the core files from avr-developers which is based on version 20, but I think you can also use the latest core from github, which seems to be named as Arduino 1, because Arduino devs merged the updates from avr-developers core. I try that one when I receive the stencils :0 (not bobuino but a 1284p chip based board).

Please post how that works out, I am up for improvement if possible.

I made small modifications on version arduino-1.0-beta4 and it works well on my Atmega1284.

Board definition is;

@Nadir

Thank you very much, you even included Timer 3

Edit: Could you upload ATmegaBOOT_168_atmega1284p.hex somewhere? thanks

The link is Google Code Archive - Long-term storage for Google Code Project Hosting. which I have downloaded.

Sure,
http://www.crossroadsfencing.com/BobuinoRev17/ATmegaBOOT_1284P_16MHz.hex

Right-click, save target as, renameto .hex

Hi, any experience with the newest sdfat (multiple cards support) and two sdcards connected?
Thx.

No, I don't have a board with 2 sockets. Yet.
The first build only supports 1, the 2nd had incorrect uSD socket pinouts.
Have Rev 2 designed, but no cards purchased. Will handlle one of SD or uSD on either side of the board.

Suppose I could try an Adafruit shield for a 2nd one as a test.

Meh bootloader does not work: avrdude: stk500_getsync(): not in sync: resp=0x00

Actually my device is 8MHz so I installed WinAVR and compiled bootloader code (from brewtroller) but no avail...

Programmer is FTDI breakout.

EDIT: Turns out common ground is needed for board and ftdi breakout. Also I attached 8Mhz bootloader which works at baudrate 38400.

ATmegaBOOT_168_atmega1284p_8MHz.hex (4.53 KB)

Call me blind, but i cannot find the PCB layout for this exact board:

It's wonderfull, and i would like to toy a little with the layout :wink:

// Per.

Ok, you are blind!
Layout is not posted, that was a paid job I did, I had permission to post the picture.
You can send a PM to skyjumper to ask him for the layout.

Hello all,

After reading through the 29 pages of this thread, and about another 50+ pages of other threads, I am still at a loss to understand how to bootload my '1284 based dev board.

I would really appreciate it if someone could please share a working bootloaders for the '1284 that works at 16MHz and 20MHz (I understand different bootloaders are needed)?

Thanks in advance,

Regards,
Madhu.

I don't know about 20 MHz, but arduino bootloaders will work at 16 MHz.

Check out the core files here for 1284's.

www.avr-developers.com

skyjumper made this bootloader for me.
(right-click, save-target-as, rename to .hex if need to).

Then get yourself an AVR ISP such as this to load the bootloader into it.

http://www.mdfly.com/index.php?main_page=product_info&cPath=5&products_id=415

add these 2 lines to programmers.txt to use it in the IDE. Tools:Burn Bootloader: w/ MDFLY

usbasp.name=MDFLY
usbasp.protocol=usbasp

and add a section like this in boards.txt

ATmegaBOOT_1284P_16MHz.hex (5.5 KB)

Hi Crossroads,

Thanks a million for all this. I was able to make changes to reflect my programmer in the IDE (AVR910).

I also replaced the pins_arduino.C with the one you have created and that it works fine.

Thank you so much yet again,
Madhu.

CrossRoads:
Sure,
http://www.crossroadsfencing.com/BobuinoRev17/ATmegaBOOT_1284P_16MHz.hex

Right-click, save target as, renameto .hex

Hey, is the source for this bootloader available?

Need to ask Skyjumper for that, he has the source and the makefiles and what not.

CrossRoads:
Check out the core files here for 1284's.

www.avr-developers.com

Is there a list of files needed strictly for the 1284p, rather then the complete package for all the processors?

Not that I know of.
