Could we use the ATmega8u2 isp port for this function (as programmer master)?
I am not sure you have understood what I've told... I want to avoid to use an external programmer for burn the bootloader on Atmega328. Could we use the ATmega8u2 isp port for this function (as programmer master)?
I've seen that an ATmega8U2 is used in the Arduino uno board as USB to serial converter. Why we don't burn the ISP function in it?We could use the B1 to B3 pins for make an ISP bus (the connector is yet availlable). This function could be used for burn the bootloader in a new AVR device or program other AVR devices.
Great idea, mimmo. This approach is not only save bootloader space and but also fast flashing speed then plus save rs232 communication and save Tx, Rx pins if we don't use it too. I love Arduino because of these essential features:
