Found another solution to avrdude stk500 not in sync error

i have duemilanove , getting sync errors whenever tried use new atmega328 chip (both , without boot loader installed). when reinstalled original 328, worked fine.

the solution had implement purchase usbtinyisp. connect duemilanove. under 'tools' menu, make sure had proper board selected (in case 'duemilanove atmega328) , programmer set usbtinyisp. note* - did have driver usbtiny and, also, menu>serial port setting isn't used under configuration.

finally, had reburn bootloader. works again!!

i should mention, here, able program new atmega chips when used borrowed arduino uno. had 2 ways fix sync error, since usbtiny saved me $$ went route.

it appear, me, arduino software has issue identifying mismatch on bootloader protocol on duemilanove board. is, assuming there difference in bootloaders between duemilanove , uno. when used original duemilanove chip, worked fine. when used blank or prewritten bootloader (assuming bootloaders same or updated version), no joy!

using external programmer, assigning proper board, , re-writing bootloader, solved sync issue.

hopefully, able illustrate issue @ hand, , helps. also, maybe generate traction on future fix.

thanks listening

i burn 328p dips unos, doesn't matter board installed in, work optiboot bootoader @ uno speeds.
