RE: [Paparazzi-devel] bootloader problem in Tiny13

[akochevar]

Tom,

do you still have the USB cable plugged in?  its possible that the board reboot, sees the reset pin being driven high, and goes back into programming mode.  unplug the programmer and reset the power and it should boot.  The flash is not gone, the board is just starting in programming mode.  Once you program it will start, which is why it remains running once you flash.
