ESP32 WROOM 32D - can't upload any code

Projects Programming

Hi

I seemed to have this issue in the past but it started working. I've followed all step of uninstalling etc but nothing works. I can not upload a single bit of code, I either get com8 does not exist or I get other errors.

Any suggestions as everything I find online doesn't help.
I've reinstalled IDE and libs, tied GPIO0 to gnd, holding the BOOT button but nothing.

The com port appears to be okay, along with drivers. Other boards, such as an UNO, ESP8266 upload code but not this ESP32.

 does not exist or your board is not connected



This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Frustrating. It works on my cheapo back up laptop but not on my Windows Surface. Tried changing the com port but nope.

Any suggestions after my update
