Question : esp32 no works after flash binary

Hi All,
i flash binary into ESP32-S3-USB-OTG by flash_download_tool_3.9.2, but the esp32 didn't work, without any lcd and led.
The start address of binary is zero, not start from 0x1000, does any possible solution for that ?

The S3 code is supposed to live at offset 0, so that's correct. What binary are you flashing? Note that the ESP32 and ESP32S3 (and -S2, and -C3) are not binary compatible; you need to have a binary that is compiled for that particular chip.

Hi ESP_Sprite
the chip is used to esp32s3, the tool chain is esp-idf, there're three binary files after compiler done, bootloader.bin, partition-table.bin, and hello_world.bin. It does not work.
the target board is "ESP32-S3-USB-OTG", the information is listed as below link :

if have any suggestion, please inform me. Thanks for your help.

Ah, so you're using ESP-IDF? What happens if you flash using 'idf.py flash'? After you flash, can you run 'idf.py monitor' and see what output you get?

Hi
Thanks for your help, i already got the message of printf from uart port, so the program is fine.
