I am trying to upload the blink example program to the arduino mini with the 328 chip. Here is what I did:
I have an uno with the 328 dip chip removed. The serial cable is connected from the computer to the uno. Power and ground are connected from the arduino to the corresponding rails on my breadboard. From there, I have the mini powered. I also have the reset pin on the uno connected to the reset pin on the mini. I have the TX from the uno to the TX of the mini and RX from uno to RX of mini. I have an led connected at digital pin 13 on the mini, to ground.
Everything seems to work fine. Here is what I can observe: When I hit the reset button on the uno and hit the upload button right after, the led I put on pin 13 of the uno (always on) blinks a few times and the TX and RX lights blink as usual and then the TX light flashes every half second. The led I put on pin 13 stays on.
What's going on?
