Arduino on Linux

hi,

this might now as well belong to the hardware section but ...

as i was neather on windows or linux able to export a file to the board (tried different settings and scenarios) without the " [VP 1] Device is not responding correctly." message i thought i try the new bootloader.
i build the isp and updated the bootloader,
which worked without any problems.
but the behaviour on win and linux is still the same.

if i download, the TX gets red once, and then the RX
keeps blinking.

could it be that my board is damaged ?
