I had that problem once... for example: if I power up directly the ATMEGA with the 5Volt from USBasp I get the blinking red problem... I don't know why but i thinks it doesn't have enough current.
CORRECT (thanks to Xoom)
Make sure you have 12V at the input of the regulator (7805)Last edited by KenshinPT; 11th April, 2011 at 03:26 PM.

my dear friend, Originally Posted by DiagService

1. fuses program - did you programed fuses accordingly?
2. your dump it doesn't fit to your interface.

(FTDI232BL and FTDI232BM are the same - BL is Lead Free and the other isn't).
If you have the RL version you need to do some modifications in the PCB and you need to reflash the GAL.
