Description

When running the sketch below with "Core Debug Level: Debug" on boards using ESP32-S3 chips with in-package (Embedded) flash and/or with in-package (Embedded) PSRAM, the Chip Debug Report shows "No" for Embedded Flash and/or Embedded PSRAM.

Tested using:
seeed studio XIAO ESP32S3 which uses an:
ESP32-S3R8 (8MB Octal SPI In-Package PSRAM)

Waveshare ESP32-S3-Matrix which uses an:
ESP32-S3FH4R2 (4 MB Quad SPI In-Package Flash and 2MB Quad SPI In-Package SPI PSRAM)
Note: As there is no board definition for this device, tested with the following boards selected:
ESP32S3 Dev Module
Lolin S3 Mini

Other boards using the ESP32-S3FH4R2 include:
WeAct Studio ESP32S3-Mini
Waveshare ESP32-S3 Mini
Waveshare ESP32-S3-Zero

Is the psram not being automatically initialized if you don't call psramInit?

[Xylopyrographer]

Same result with:
psramInit();
commented out.

So, no, that line is not required.

The chip report shows "No" for Embedded Flash and for Embedded PSRAM.

[me-no-dev]

We just print what the chip says. We have no control over that and has nothing to do with actual config. It should show what is in the package itself, not what is under the module can.

[Xylopyrographer]

That is how I thought it should be.

In the boards tested one, the XIAO ESP32S3, uses an ESP32-S3R8 which has 8MB Octal SPI In-Package (Embedded) PSRAM.

The other board, the Waveshare ESP32-S3-Matrix, uses an ESP32-S3FH4R2 which has 4 MB Quad SPI In-Package (Embedded) Flash and 2MB Quad SPI In-Package (Embedded) SPI PSRAM.

Should these not be reflected in the "Chip Info" section of the chip debug report?

[me-no-dev]

They should, but I guess their fuses were not burned or not marked in production. Again, we just print what the chip tells us

[Xylopyrographer]

OK. Gotcha. QA problem at Espressif I guess.

Thanks.
