so when i upload a small code like blink it works however when i upload anything else it stops uploading and says=
avrdude: verifying …
avrdude: verification error, first mismatch at byte 0x2480
0xff != 0x0f
avrdude: verification error; content mismatch
avrdude done. Thank you.
i am using sparkfun pro micro.
Which ISP loader hardware are you using?
to burn the bootloader i used an arduino uno
I’m still not sure where your error is. Are you using your Uno as a “Arduino as ISP” to upload to the pro micro? Or are you uploading the sketches with the USB port? There are various debugging options you can turn on, but they depend upon what you are doing. If you are using avrdude directly from the command line, you can add options there, or if you are using the Arduino IDE you can choose “preferences” from the “file” tab, and there is a check box for “Show verbose output during” → upload.
ok so i am derectly uploading to arduino mico the error is=
avrdude: verifying …
avrdude: verification error, first mismatch at byte 0x2480
0xff != 0x2a
avrdude: verification error; content mismatch
avrdude done. Thank you.
can i use something different to upload to my micro

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.
i saw this in compiling error Warning: Board arduino:avr:atmega16-8 doesn’t define a ‘build.board’ preference. Auto-set to: AVR_ATMEGA16-8
