Using Arduino Uno instead of FTDI cable to program 1284p w/ Optiboot

[system]

spcomputing:
I have used the Atmega Board Programmer and it is nice, and it appears to install the 1284p well enough, but again, uploading a sketch ~25kB fails with the paged_write error. Blink uploads fine. I have also tried pulling the hex out of another hex file and putting in, same problem.

The Atmega328 works flawlessly. The 25kB sketch uploads perfectly.

What gives the paged write error? The bootloader? My sketch? Please clarify and post any messages you get.

Hi Nick,

It has the stk_500_paged_write error in the middle of uploading a large sketch (Show Info modified for a Mega). Blink uploads fine. This problem seems to be around serial pocket programmers(USBasp) and Arduino as ISP.

The only 1284p bootloader that uploads consistently with Aduino as ISP is WestfW's Optiboot for UART1. I can somehow get Original Might 1284 (16MHz) to work as well. cyclegadget has no problem with Atmega Board Programmer and an Arduino and the 1284p SMD/CrossRoads Board. AVRISP MkII have no trouble at all.

It is quite the enigma wrapped in bacon. I am going to build an exact half-board minimal-duino from your tutorial to see if there is something else causing trouble.

Even with this hic up, Atmega Board Programmer is a very clever sketch, great for my 328's!
