at first i just downloaded and unzipped files. when that didnt work i copied boards.txt from 1284 folder to the avr folder. at least the 1284 options showed up then but still that error. then as a last resort i put the original boards.txt back and added the 20mhz no-led entry to it. then got serious about editing and changing and of course things got worse. initially though no luck before any changes or editing.i will delete all this and start over from scratch. as always your help and patience is appreciated.
so i reformatted the hd, reinstalled windows and followed instructions again. this time it worked. as confirmation the original crowded image was restored and the same procedure duplicated. this time it failed again. so something on the drive, maybe registry or other arduino droppings interfere.
always zip file because i agree installers in general are evil. as mentioned i downloaded another copy of 1.6.4 and know exactly which version is being used because i always click on the exe flle. no task bar, desktop icons. or win start menu here. in the "crowded" partition i have every version of arduino from 0013 up and something there conflicts. maybe some rainy day i will take time to find exactly what.for now if the need arises to use arduino with this chip i can always restore that virgin windows partition which works fine. atm the only reason to do that would be enhancing the bootloader and i wouldnt even start on that w/o a lst file.
it was a surprise to see the noled version so much bigger than the led one. not 2x but almost half again. so much for my theory that pretty flashing lights take up valuable memory space.
i would have to agree that its better to have correct source with the binary. in my case the list file is the source so no biggy. since im trying to cram a lot of non-standard function into minimum boot block the smaller older images are more useful. it only took me a couple minutes to change baud in the old/small opti to 20mhz.
im just glad to have some working m1284 code as a starting point. and very happy libraries are improved so more programs work compared to last time i tried.
I have just spent the week reading everything I could find about the 1284p, from MB's site thru the forums (as crosslinked), and I'm excited. Downloaded the zip for the current IDE and got it all installed in moments.(I just wish I had a board to test with ;-)
Curious, however: it's been over a year down this road and there are still issues with the bootloader sources?? Why?
I've also noticed that the new IDE doesn't list the 1284[p] as a Boards-Manager Option. No one has looked into that process?
In any event, I really want to thank the lot of you for hammering it into shape and getting it over the 1.6.x
