Can not boot loading Cannot bootload again after changing the board?
we We are so tired and would like to get help with this . We are trying to boot-load bootload using the arduino Uno.
We have an atmega 328p smd , that we are trying to bootload. We have connected all the right pins, added to the boards.txt the "Atmega328 on a breadboard(8mhz internal clock) " .
Than i Then I have chose chosen from the "board" menu , this option (internal clock) , and uploaded the program. it worked .
Later, i I wanted to try and bootload for external clock so i I chose from the boards menu the pro mini with 5v board.(is it wrong?)
Not only that i I got an error, now, i cantI can't bootload the internal clock again !!
why cant Why can't we bootload again? did Did we damage something ? can Can it be reseted reset again ?
howHow can you bootload for external 16Mhz ??
