Hello All, I am having problems with Atmel FLIP, it refuses to talk to the microcontroller. I tried using USB with hardware reset condition (ISP connected to GND via 2.2K resistor and RST = Vcc to reset). D+ and D- of the chip connects to the USB cable to the computer. I've installed the USB driver many times. I usually get the error "Cannot open Port" or "USB driver NOt installed" even though I just installed the driver. I have tried this on different computers and still I couldnt get it to work yet. Is there a way of running the bootloader software other than this? And how do I know that the bootloader software is in the memory of the chip? Thanks.
hi, I tried using USB with hardware reset condition (ISP connected to GND via 2.2K resistor and RST = Vcc to reset). I'm sorry but just question: have you released RST pin then? The firmware bootloader is called with next steps: 1) reset = Vcc; 2) /ISP = pull-down resistor to GND; 3) reset = release (flow); So the question: did you do step 3? Good days, Oleg
