Hi,
upon connecting the RX wire sometimes my ATmega324 hangs somewhere in the RX interrupt handler (found this out with debug LEDs, as I can't use JTAG). I don't know how to proceed further when looking for the error, as I have no clue about assembler.
I have excluded ground loop issues and tried various config options with no success.
Is there any config switch to make the whole thing more robust? A system freeze upon UART cable connection is unfortunately something I can't live with.
