Can not program ESP-S3 with Flash Download Tool

Good day,
I'm trying to download the bin file to an ESP32-S3 on a custom PCB using Flash Download tool v3.9.5 and an ESP-prog, but it does not work.
I am able to upload and run my firmware using Platform,io.

Any suggestions on how to get this working?

Looks to me like it successfully flashed; how do you figure it didn't work?

I tested it with a board with the firmware already loaded through my IDE.
After I upload using flash tool the code doesn't start up.
Are my addresses maybe wrong?

Possibly. If any, I seem to recall that for an S3 the bootloader starts at address 0. Not sure if PIO works that way as well, but for ESP-IDF, after flashing, you can find a file called 'flash_args' in the build folder that tells you where the binaries should be flashed.

This worked, setting the bootloader to address 0x00.
Thank you

Hi, I am using the C3 and I have the same issue. The flash runs all the way and indicates "finish", but the the program is supposed to flashing some LEDs and it is not. How did you resolve it?
P.S: I have already set the bootloader to 0x00. I am just wondering if you can suggest anything to me.

This was correct and fixed my problem. Thank you!
