ATMEL Mega1284P evaluation board avalible

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;

atmega1284.name=Bobuino W/ ATmega1284P

atmega1284.upload.protocol=arduino
atmega1284.upload.maximum_size=131072

@Nadir

Thank you very much, you even included Timer 3

Edit: Could you upload ATmegaBOOT_168_atmega1284p.hex somewhere? thanks

The link is http://code.google.com/p/brewtroller/downloads/detail?name=Sanguino1284P.zip&can=2&q= 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 ;-)

// 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.

Are there any plain basic 1284 boards with UNO foot print? The Bobuino is cool but way more features then I need. Essentially need UNO foot print, more RAM then 328 offers and shield compatibility. Be connecting Ethernet shield and a GSM shield. Much prefer on board USB over external FTDI.

I have an UNO32 which is PIC32 based. Great little board and compatible with shields. But libraries have quite a few gaps. What I am doing should be fairly simple to due with Arduino environment. Right now seems much less of a path of resistance then delving into MPLAB and Microchip Ethernet stack.

But with the RAM requirement exceeding what the 328 has to offer the 1284 is an appealing choice. I've looked at adding SPI RAM or FRAM, but I'd rather have less parts count.

You want a bare Bobuino board & just populate the parts you need? Leave off the SD parts, RTC, extra IO pins, etc. I could order a batch of PCBs, you build up what you need.
