ADB (USB Debugging and ClockworkMod Recovery).

There are three different modes in which the Incredible (or the EVO!) can connect to a Windows system: I thought I'd maybe add to that or create an alternative article.

#Install bootloader on usb drive drivers#

The schematic I added a few posts above is still the same, I added it in higher resolution again.Monitoring the traffic on the unrEVOked IRC channel, it's clear that there is a ton of confusion about the USB drivers needed, despite the excellent article on the unrEVOked site. The fuse settings are wrong (the chip is not programmable over ISP) The HWB pin is connected to ground, maybe thats the problem I will go back to it tomorrow or so, maybe I' m trying to fix this for too long now.īut I guess it is not a hardware wiring problem. Įverything worked fine! So it is not programmer. but nothing found.įor a comparsion, I hooked up another board with an atmega328p on it and tried to read the fuses, flash.

When I try to read the voltage over the AVRISP it works and shows 5.3V (a bit high, but is still ok with the atmega32u4).īut when I try to read the signature it doesn't work (reading failed). Then I connected it to the main atmega32u4 using the ISP Pins, plugged in a 5V Powersupply to supply the proc during programming.

Ok, now I have the AVRISP mk2 from Atmel.Īfter installing, I plugged in the programmer and it showed me an upgrade in Atmel Studio 6.

Now I can back to my question: How can I install the bootloader and set the fuses. They told me, that the chips they soldered are completely empty. Do you mean it should be conntected to GND all the time?ĮDIT: I just contacted the pcb manufacturer. It looks like 32u4s are supposed to come with a bootloader already loaded, but it's one that requires that you pull the HWBE pin (PE2 - chip pin 33) 'low' during reset to activate it.Īs you can see on the picture (sorry for the low quality, will make a better one), pin 33 is connected to GND. 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. 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.
