In reply to Sara Santos. Hey actually I'm getting this error message whenever I upload the code then press the boot button while connecting message appears: Download mode successfully detected, but getting no sync reply: The serial TX path seems to be down.

Windows has stopped this device because it has reported problems. (Code 43)

Hi.
After uploading the code and seeing those messages, press the ESP32 RST/EN button.

Hello
My story with ESP that used to work few months ago
is that it uploads the code fine with “Leaving…
Hard resetting via RTS pin…” message at the end but the board does not execute
anithing. (Including simple “Blink” and “Serial” examples).
Thank you.

Hi.
Try to connect your board using Arduino IDE and upload an empty sketch.
Then, try to install micropython again.

I think I have a corrupted boot.py or main.py file. I have had success running various simple files and getting addressable led strings to work. I ran a file that was a bit more complex with a potentiometer, a button and two leds. It went into an infinite loop citing errors at 0xffffffff. Neither c nor the onboard reset button work. If I disconnect it from the usb port, upon reconnecting it still has the same problem.
Do you have any advice?

Hey all,

Having trouble switching from ESP8266 to ESP32! I’m running into a roadblock compiling code and getting this error message:

“exec: “{runtime.tools.esptool_py.path}/esptool.exe”: file does not exist”

Basically, it seems like the system can’t find the esptool.exe file needed to compile for the ESP32 Dev Module. I’ve tried some solutions I found online but nothing’s working yet.

Anyone else face this issue before? Everything runs smoothly with ESP8266 boards, so it’s gotta be something specific to ESP32. Help a newbie out!

I can’t help but to write this comment to express my gratitude towards you. I was getting frustrated because my computer was not detecting my ESP 32 CAM. I tried downloading drivers, I watched Youtube videos on people setting up their ESP 32 and nothing worked.
I was starting to think that maybe there was a problem with my brand new ESP 32 CAM module.
I decided to give it one more try and to look online for what was going on.
The first google result was this article with the line “Make sure you USB wire has a data wire” highlighted.
I have tried 3 different USB wires before seeing your article and I look around for the last USB wire I had, hoping a lack of one was the issue all along and that this one has a data wire; and it finally worked.

HUUUUUUUUUUUGE THANK YOUUUUUUUUU!!!
