Hi guys,
I was trying to flash my Arduino R3 with dfu-programmer. It didn't work and now it isn't recognized by the IDE anymore. I checked in my system info and it shows the atmega
and shows that it is in DFU mode.
Unplugging doesn't work either. What can I do? Please help me!!
Thanks
Hi Moritz,
it seems that you somehow broke the boot loader. To repair that pls use the search function of this forum. There are dozens of threads which will tell you how to do that. The methods vary and depend very much on what hardware you got.
Interesting enough: why didn't you use the normal IDE together with a USB cable to upload your sketch?
And: instead of USB3 use, if possible USB2. USB3.0 is sometimes troublesome.
The arduino worked flawlessly before so its not the usb cable. I think the bootloader is empty because I was able to clear it, but uploading the hex code didnt work. And I seached the forum for an hour but I wasnt able to fix it.
The bootloader must not be empty, it must be present to upload any sketch.
If the boot loader is not present or broken, you won't be able to upload anything.
