ESP32 Forum

I am facing a problem with getting output for a sample code(helloworld) that we were able to upload to ESP32 S3.

I am using the following configurations

Windows 10
Visual Studio Code Version 1.62.3 with ESPIDF Extension
Python version 3.8
ESP-IDF Version (4.3.1 latest) - supports ESPS3Beta3 (Which is ours)
Board Version: ESP32 S3 WROOM 1 E2 N8R2

We put the ESP32S3 in boot mode by pulling down GPIO0 and GPIO46 to GND, and was able to successfully flash the code. But the MAC address for this is MAC: 00:00:00:00:00:00.
We have tested yet another ESP32 S3 on a new board and the same No MAC Address issue is there. But it is flashing the code. The following is the log of code upload:

As you can see Even Though the MAC Address issue is there for 2 separate boards, we were able to flash the code completely,

Now coming to the second issue. When we monitor the uploaded code on both the ESP32 S3s, the following reset error is coming as following:

ESP-ROM:esp32s3-20210327

But we have double checked the target device and it is set to the correct chip that we have. Because unless it is not set to the correct chip we won't be even able to upload the code in the first place. We have checked eFuse issues and that also didnt help us to solve the issue.

Any help would be appreciated.

Thank You.

The main ESP-IDF tree stopped supporting the beta silicon since the final S3 hit the mass market, sorry. We suggest you switch to that chip.

What do you mean with switch to that chip? I just purchased two months ago this Adafruit feather ESP32-S3 board and it came with ESP32-S3(beta3) chip and I'm now getting the Invalid head of packet error. Should I ask Adafruit to replace the board with one that has the final S3 chip?

That is odd, given that timeframe I'd expect you to get non-beta silicon. Sounds like it's more likely something else is going on. Your esptool.py is rather old (v3.1; current is v4.3), perhaps you need to upgrade esp-idf?

Upgrading the esptool to 4.4 fixed the problem. Now the correct chip and MAC address are listed. Thanks!

i have custom board esp32s3 , not getting Wi-Fi signals , i have tried many code esp32s3 chip, its required extra command enable wifi signal or any other issues , i have tried many codes and examples for test own desgin esp32s3 , all other task ok about this , generally working fine , but not show wifi signal as ude soft app or try to connect to wifi
please guide how to get few inches wifi signal with out matching circuit or not required any small antenna that connect to esp32s3
