Interrupted sketch upload results in bricking?

[imrehg]

imrehg:
Could that interrupted upload result in bricking or killing the board? Or the bootloader got damaged somehow? How could I test these things, or is there a way to fix it?

It should not do that (get killed). Do you have another board? (you could test the first with the second)

Yes, I have another board, how could I test the functionality of this one?
