More Information

Burning ESP32c3 is normal, but ESP32s3 cannot be burned.
I will merge the three generated bin files and download them using the esphome tool（ https://web.esphome.io/ ）It can be downloaded normally and the chip is running normally

Other Steps to Reproduce

I Have Read the Troubleshooting Guide

• I confirm I have read the troubleshooting guide.

The idf5.1.0 previously installed on another computer was able to burn the same S3 development board normally. Now I have tried installing multiple versions of idf, but none of them can burn this ESP32S3 development board
Use https://web.esphome.io/ and flash_rownload_tool_3.9.7.exe tool can burn, which should indicate that my hardware is functioning properly

[ljm996054544]

I have installed IDF4.4 and can burn ESP32S3 normally, but my project requires IDF5.1

[ljm996054544]

Copy esptool.by from IDF4.4 to idf531, and idf531 will be able to burn esp32s3 normally. However, I don't know the specific reason for this. Currently, it can be used normally, and I'm not sure if there are any hidden dangers

[ljm996054544]

esptool.by

I was wrong. Replacing the esptool.by file can allow esp32s3 to burn normally, but it can also cause strange compilation issues

Hi @ljm996054544 can you please provide the images? I will try to reproduce it.

Hi @ljm996054544 can you please provide the images? I will try to reproduce it.

images.zip
I am using the hello_world demo

Thanks for sending the images. I was not able to reproduce the issue unfortunately. I see from the log that you tried v4.7.0 and v4.8.1 and neither worked for you.

Could you please try installing an older version of esptool manually and see if e.g. v4.6.2 work for you? The docs contain instructions on even how to change the esptool version in the context of ESP-IDF.

Sending the log with --trace option enabled in esptool.py would also be helpful.

You can also try to flash the images with --no-compress option and see what it does (this might be workaround but not the solution).

The reason is the difference in flash size. Your flash command uses 4MB and the connected device has 8MB flash. To avoid such issues build the firmware images for 8MB.

[ljm996054544]

原因是 Flash 大小的差异。您的 flash 命令使用 4MB，连接的设备使用 8MB flash。为避免此类问题，请构建 8MB 的固件映像。

I am using ESP32S3-N16R8, and I have set Flash to 2/4/8/16, but none of them work

I manually installed esptool and tested one version after another. (Master) v4.6.2 can be used normally, but versions greater than 4.6.2 will report errors

@ljm996054544 okay, thanks for trying this, can you please send the logs with --trace option, one from v4.6.2 and one from newer (which does not work). I will take a look at it. Also, did you try the --no-compress option?
