#INSTALL BOOTLOADER ON USB INTERFACE INSTALL#

But I can't read the fuses with it, because I don't know any software that supports the atmega32u4 fuses. After settings the fuses with my stk500v2 it worked. I already had that with an atmega328p, which was unprogrammable with the usbasp. It looks like it is a fuse settings problem.

#INSTALL BOOTLOADER ON USB INTERFACE INSTALL#

With the USBasp it doesn't work, I can not install the bootloader. You have a Programmer that connects to the SCK-MISO-MOSI-RESET-+5V-GND pins for downloading the bootloader code? But both programs don't support the atmega32u4 unfortunately. Until now, I used Avr Burnomat to set fuses and Khazmara for burning hex files (all over USBasp). I also have a STK500 V2 (from ebay, I guess its a clone?). I have an USBasp, on one board (we have 4) I tried to burn the leonardo bootloader with the arduino ide 1.01, but the process stops with an 'out of sync' error.

How can I solve that? I used the search function on different forums, but haven't found a solution yet.

If the schematic is ok (than the layout should be right too, board was made with a professional manufacturer), the only reason for that problem I see is that the atmega32u4 is empty. I don't see any errors, but maybe I just don't want to see it -)? There is no new device showing up in the device manager, nor any kind of 'driver install' messages. I thought that when I plugin the board, it should automatically try to install the driver on my windows XP (32bit) pc. It is a simple board, more or less just the chip, a 16mhz crystal with 22pF caps, 10kO resistor for pullup of RST line, USB connector.Īll pins are connected simply to pinheaders and have no other things attached. A friend of mine has made a board with an atmega32u4.
