Crossroads,
Congrats on the board and the hackaday mention!
Thanks!
Bob,
Did you do anything with the software? Step by step instructions for modifying the IDE? Got my board working eventually, it's just a shame that there is no built in support. It looks a great bit of kit though.
What? I sent you an e-mail, same as the other folks who bought a board, with a document with directions needed to make it work - location of my zip file that has all the files I modified, example sketches, links to needed libraries. I sent it a 2nd time when I updated it slightly. I hadn't heard anything back from you, figured you were all set. The e-mails didn't bounce, so I assumed your e-mail was good.
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.

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.

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.
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.

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.
