Flashing instruction for ESP32-S3

Post by detlevo » Sat Feb 12, 2022 2:30 pm

Hello,

I think the flashing instruction on the firwarepage for the Espressif ESP32-S3 board (with and without SPIRAM) is incorrect. The firmware should be flashed to address 0x0 instead of 0x1000.

Yes, I agree those instructions appear to be wrong.

@Detlev did you by chance use the Generic binary(ies) provided from the downloads page for your installation? I have a ESP32-S3-WROOM-1 N8R8 that I can't seem to get to work with the generic binaries.

Nope, the generic binaries don't support the 8MB PSRAM variant because these need to address the RAM differently (octal instead of quad). Therefore you have to build your own firmware. Note as well, that you should disable the USB support for now because otherwise you won't get the REPL on the standard USB port connected to your computer.

By Standard USB you mean the connector mark UART?

Yes. The one marked with "UART" was used by me.
