i updated my board to mk4 without burning the bootloader, so now my motors doesnt work. I realized i need to burn the bootloader and I cant so i keep getting an error someone help.
In some cases, not sure why, selecting "ArduinoISP" does not work with all Uno boards, especially if it is not genuine. I have an Elegoo UNO R3, and had to select "Arduino as ISP" instead.
I recommend that you try this:
Do "File New" so that you get a default sketch, e.g. void setup() etc.
Assuming that your UNO and 3D Chameleon board are connected correctly, Upload that to your Uno board so that you now it is "fresh"
Select "File > Examples > 11.ArduinoISP > ArduinoISP - a new window should open with the example file. (First Image)
Upload the example sketch to the Arduino
Select "Arduino as ISP" under "Programmer" (Second Image)
Select "Burn Bootloader"
Then follow the steps to put the new firmware on the Chameleon.
