Hi,

We want to use the esp32 flash download tool to flash our esp32-s3 based modules with the firmware for production.

I can flash the firmware via VS-code + espressif-extension without any problems.
But when I use the Flash Download Tool to write the firmware onto the esp32-s3 it is not working.
I get the following output form the tool:

Code: Select all

Uploading stub...
Running stub...
Stub running...
Changing baud rate to 1152000
Changed.
NO XMC flash  detected!
SPI_BOOT_CRYPT_CNT 0
SECURE_BOOT_EN False

 is stub and send flash finish

The only thing that works with tool is to erase the flash. This is working perfectly.

How can I fix this?

Some Setup Infos:
- esp32-s3-wroom-1u-n16r8
- Esp32-s3 Flash Download Tool V3.9.6
- Using USB-Pins to do the firmware download via UART-protocol (I also tried USB protocol, but same problem)

Solved it. It was a mistake on my side. I did not choose the right files for flashing.

But the message

Code: Select all

NO XMC flash  detected!

is still a little bit confusing, since all esp32-s3-wroom modules have XMC flash or not?

They have flash, but it's not necessarily manufactured by XMC.

I'm having the same problem and am new to the flasher tool. I currently have the main.bin, partition_table.bin, and bootloader.bin selected. Are these correct? Thanks
