I am trying to upload just the basic Blink LED example to an Arduino Pro Mini and keep getting out of sync errors. I've tried several different cables and 3 different Minis to no avail.
Two of the minis I know work and I somehow uploaded a hex firmware to it because there is output to the serial monitor.
So the cp2102 is a sort of module i have though with issues since it is not a 'true-prolific' (at least mine isn't) so has the driver for that been installed correctly ?
is that what what the markings on the crystal say ?
Is it a 328p or a 168 ? i mean what does it say on it, and/or have you tried both options ?
How about doing the euclid thing and trying every version of the processor with all the options of the port and all the options of programmer?
Also do you have the right USB drivers? Try googling (OS) USB drivers fir (name of board)
Just a thought because my MacBook Pro refuses to see a Nano that I programmed on it half an hour earlier without being restarted or going to sleep and the way to trick them both is to do the stupid try-options-you-know-are-wrong thing.
