the mighty 1284p bootloader.

hi,
ive, got the following atmega 1284p-pu for a project, ive build a bare bones board for it in an attempt to get the bootloader to load, ive also the in house expert crossroads to see if i he has any of his boards left so i can build a good programmer,

could some one please show me a good example of a tutural that works ive searched the forum and found a few but there to be a little mod here and there im really after a tutorial that works please if they exist.

thank you

I use Atmel AVR ISP MKii to install my bootloaders.
I think Nick Gammon's Arduino as ISP will do 1284's also

Software mapping of pin names to physical pins is done in pins_arduino.h which is where the Bobuino variant comes in.

Oh, and I do have bare boards available.

Yes, Nick's code worked when ArduinoISP failed. I'm ashamed to say I did not return to the ArduinoISP code to determine why it failed... I have come to like Nick's code better.

Unfortunately, I've never gotten around to learning how to use those AVR programmers, so I always use Arduino as ISP with my UNO board to program 1284Ps. Has always worked fine. I don't recall doing anything out of the ordinary, as listed on the Arduino as ISP page.

How to use them? You plug it on the board, select Tools:Programmer:AVR MKii, thenTools:Burn Bootloader.
IDE makes it pretty straightforward.

hi rob, look faward to receiving the boards will give you a shout when they arrive cheers

Partly, it's one of those things that's buried in the queue. Partly, it's because I bought an AVR programmer from pololu, and could not get the drivers installed properly. It installed like 2 comport and 1 USB driver, as I recall, and something was hosed. I just decided not to screw with it.

However, all I was saying to OP is I've had no trouble using the UNO to burn the boot loader in the 1284s.
