Problem to upload Code to Arduino UNO

Development Tools IDE 1.x
8

Hi again,
It worked, thanks again Koepel!

To summarize for others who have the same issue:

  1. Issue: When attempting upload to Arduino via IDE, got error message
    "avrdude: verification error, first mismatch at byte 0x0000
    0x62 != 0x0c
    avrdude: verification error; content mismatch"
  2. Tried to no avail: USB-port and Device in menu "Tools -> Board" and "Tools -> Port"
  3. Tried succesfully after a few iterations: Buy a Bootloader, simply plug it via my USB-port and attempt "Burn Bootloader" -> got error message
    "avrdude: Warning: cannot open USB device: Function not implemented
    avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='[A Vendor]' product='USBasp'
    Fehler beim Brennen des Bootloaders. [german for Error while burning the bootloader"
  4. Installed a USB-driver via https://zadig.akeo.ie/
  5. Re-Attempted Step 3). When it failed (once), I changed the driver of the USB-port using the software from step 4)
  6. Re-Re-Attempt was succesful, now the upload to Arduino in the IDE works again
