avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xe0

Hello Everyone,

I've been getting this error message every time I try to upload code to my Arduino Pro Mini 3.3v. None of the solutions I was able to find through quick searches have given me any results.

I recommend giving this guide a try:

https://learn.sparkfun.com/tutorials/using-the-arduino-pro-mini-33v

I've already gone through that guide. The codes were uploading fine at one point but when I started testing another code with some hardware it seemed like it became more inconsistent when uploading. It wasn't having any trouble running the code that I already had on it for a little then it froze and won't reset.

I recommend disconnecting whatever hardware you have connected to it and upload the example blink sketch. It is possible that it is damaged.
