Maybe it's just me but I don't understand which product, which version or anything else!

Hi.
I'm new to Pinguino and MCUs, but want to ask a little bit about this erase incident...

a) What board model and MCU are you using?

b) What did the guys from the shop told you about possible reasons?

c) Every time you return to the shop, what they do? Replace your board with a new one, or, reprogram the CHIP (MCU)?

d) If you using a breadboard Pinguino, what CHIP are you using and what is the version of the bootloader that they pre-load on the CHIP?

e) Did you have the exact same problem on different PCs?

f) What PC do you use (Linux, Win or Mac)?

Some years ago I had a trouble with defective PC Power Supply Unit and one USB HD Unit, in a XP machine...

I'm playing a lot with PICs, bootloaders, serial (FT232), AVRs and I'm just curious about this "erase" stuff...

Regards,
Valter
One more question...

z) What exactly they mean by "erased"? The entire chip is blank, or the user application is NOT on the chip?

Thanks,
Valter
