Please let me know if I've screwed anything up here, or if there is something more you think others would like covered.
I swear when I see errors I somehow convert them in my mind and then I don't actually see them
For anyone wanting to play around with the Nano PCB and the small programmer:
Here is a link to my Hex program. Hex Code ZIP file.
You can change Settings and reprogram to verify for yourself that EEprom is still valid and settings don't change when uploading Hex Code.
Here is a link to the Program used in the How to Nano posts. The AvrDudess program
Anyone trying to download, pleas tell me if you get any error at all, with the download operation !!!
EDIT: The last Line in the previous post should read "Intel HEX"
BTW I found this from Microchip: Brown-Out protection:
"Note that AVR ® internal Flash Program Memory contents are never affected by insufficient power supply voltage."
The EEprom can be corrupted (inverter settings) if BOR is removed.
The main reason reported for removing the boot loader - During some brown out conditions, the Boot loader will try to start/stop and could corrupt your Flash program memory.
