My son (9yrs) has an Arduino UNO and cannot upload any new software to it.
I am trying to help him, but so far to no avail, and hence this call for help.
I have tried google, and tried recommended steps, but it did not work.
I will try to describe the problem as precisely as I can, but please tell me what my description is missing.
Versions of HW and SW:
- Arduino UNO
- Arduino IDE v1.8.15
- Bootloader USBasp by PAradeisetronic.com, see amazon ASIN B01CPZ52MI
When trying to upload any software, Arduino IDE says:
"avrdude: verification error, first mismatch at byte 0x0000
0x62 != 0x0c
avrdude: verification error; content mismatch"
Checked: USB-port and Device in menu "Tools -> Board" and "Tools -> Port"
After looking up severa threads here, some members solved the issue by burning the bootloader. I hence purchased the above mentioned hardware, and
- selected "USBasp" from "Tools -> Programmer"
- tried "Born bootlaoder" and got the following error message:
"avrdude: Warning: cannot open USB device: Function not implemented
avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='www.fischl.de' product='USBasp'
Fehler beim Brennen des Bootloaders. [german for Error while burning the bootloader"
During both the failed upload and failed bootloader burning, the Arduiono LEDs show green light at "ON"-LED and orange light at "L"-LED. all other LED are off.
The Bootloader shows red light at "LED 3".
Many thanks in advance!!
Have a nice day,
