Hi,

When i boot esp32-s3-wroom-2(ESP32-S3-DevKitC-1) this messages appear:

Windows vs Unix thing. It's a warning only, esp-idf corrects for this under the hood.
2) For OPI Flash, Use Default Flash Boot Mode ?
3) What does SLOW READ configuration of flash memory mean ?
boot.esp32s3: SPI Mode : SLOW READ
From what I know, the bootloader isn't capable of controlling the OPI flash in OPI mode. What it does instead is to fallback to a single-wire SPI mode that OPI flash supports as well. As soon as the 2nd bootloader takes over (IIRC, could also be the app), the flash is switched to OPI mode.
4) SHA-256 comparison failed, Attempting to boot anyway... ?
Not sure. Will ask around.
5) spi_flash: Detected size(32768k) larger than the size in the binary image header(4096k). Using the size in the binary image header ?
boot.esp32s3: SPI Flash Size : 4MB
spi_flash: detected chip: mxic (opi)
spi_flash: flash io: opi_dtr
Note: i already erased the flash memory with: idf.py erase-flash
You selected 4MiB of flash in menuconfig (under serial flasher options iirc) but you have 32MiB of octal psram. The app will pretend that there's only 4MiB installed.
6) Is this configuration good or bad or does it depend on the application ?
spiram: Initialized, cache is in normal (1-core) mode.
Should be OK, I think it's a remnant of ESP32 code.
7) FLASH: DO NOT USE FOR MASS PRODUCTION! Timing parameters will be updated in future IDF version and PSRAM: DO NOT USE FOR MASS PRODUCTION! Timing parameters will be updated in future IDF version ?

NOTE: The application are running.
It's what it says. Running octal flash/psram on the maximum speeds needs some timing parameters which we probably got 'ballpark correct', but we might update them after doing more tests.

Got an update: Seems the SHA check failed might also be because of the wrongly selected flash... seems esptool.py under some circumstances auto-corrects some values in the bootloader header in order to make those match the detected flash, however this makes the SHA1 checksum not match anymore. We're working on a fix for this; for now you can ignore it.

I set to 32MiB in menuconfig.

I have two files inside root project directory.

Sdkconfig and sdkconfig.old

Will esp-idf be using the sdkconfig.old file ?

Then how are you flashing the binary? Are you invoking `idf.py flash` or using esptool.py manually?

I am flashing using flash icon from "ESP-IDF VS Code Extension" in visual studio code.

Note: i added more information in my previous answer.

Did you make sure that ESPTOOLPY_FLASHSIZE_DETECT (Serial Flasher config -> Detect flash size when flashing bootloader) is disabled ? It is usually enabled by default. This will override any user defined flash size.

The visual studio code extension uses the project's build/flasher_args.json file for esptool flashing arguments, which are set by sdkconfig values.

@ESP_bignacio,

sdk_config and flasher_args.json image in annex.

Dout mode is only for flashing the program on esp32-s3, correct ?
In "running" mode the esp32-s3 flash memory communication is octal, correct ?

"flash_mode": "dout" in file flasher_args.json.

Disable that 'Detect flash size when flashing bootloader', and see if that helps, please.

I disabled the 'Detect flash size when flashing bootloader' and the sha error and flash size error disappeared.

Shouldn't it work with 'Detect flash size when flashing bootloader' enabled ?
There must be some bug, right ?
