[avrdude-dev] avrdude ethernet

[Nagy Zoltán]

Hi avrdude developers!

I'm working on a project to upload an application code to an arduino board over 
the internet. I'm using an arduino uno with an ethernet shield. I want to write 
a bootloader which works like a tcp client it gets the new code from a remote 
server and puts it in the program memory. 


So from anywhere I can upload code to my board using a simple http request to 
the main server and it will compile and forward the hex file to my board(The 
server and the board are in different location). The problem is that I have to 
interrupt the current program somehow via the internet, when I want to send the 
code, and make a controller reset.

In the avrdude what kind of interrupts are used to do this, how does it works 
on the serial port? for instance in this case: avrdude -v -v -v -v -patmega328p 
-carduino -P\\.\COM5 -b115200 -D 
-Uflash:w:$(ProjectDir)/Debug/$(ItemFileName).hex:i 


Thanks in advance!
