I have a working Uno clone board.
I bought a couple of bootloaded ATMEGA328P-PU chips (Optiboot) and tried them in my Uno board. When I tried to download a sketch to them the TX led blinked faintly, that's it, and I got the typical stk500 synchronisation message. Put the original chip back in and everything working fine.
I asked the Ebay vendor if the chips should work in an Uno board but they didn't answer that question, they only said to hook it up to a crystal, etc and a serial connection. Are there different versions of bootloaders, and some won't work in an Uno (clone) board.
My intention was to just pop the bootloaded AVRs into my Uno board, download the sketch to them then use the AVRs standalone in a circuit.
Is my thinking wrong. I've also just seen on Youtube that this could mean the AVRs are not actually bootloaded.
Cheers,
Keith.
