ok, I have spent pretty much time reading and trying to send a sketch to
a bare 328 stand alone on breadboard (after engaging a new board) using a uno as programmer.
then i tried to a nano. Same luck , different message.
What I do (last) is :
1 load a uno with isp. “done uploading”.
2 disconnect usb. close IDE. Connect pins 10-11-12-13 to 10-11-12-13 of nano, plus +, -.
3 reconnect usb. Open IDE. use port -unoport, board -nano. Open sketch.
4. Upload using programmer
Sketch uses 974 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
An error occurred while uploading the sketch
Tried rst-rst connections (instead of 10-10) no luck
The objective is that I need a fast start (<70msec) and I hope it can be achieved with no bootloader.
Any help is welcome
