ESP32-S2-WROVER question

[bridger6649]

I have a custom board with an ESP32-S2-WROVER module. (Board and parts sourced from JLCPCB).

REPL etc. all works fine.

When I flash it with new firmware, the initial output is as follows:

esptool.py v3.2-dev
Serial port /dev/cu.usbserial-143401
Connecting....
Chip is ESP32-S2
Features: WiFi, No Embedded Flash, No Embedded PSRAM, ADC and temperature sensor calibration in BLK2 of efuse V2
Crystal is 40MHz
MAC: 58:cf:79:38:7a:3c

According to its datasheet, the ESP32-S2-WROVER has 4MB of flash and 2MB of PSRAM.

That being the case, why does the Features line say: "No Embedded Flash, No Embedded PSRAM"?

Can anyone shed some light on this?

Thanks!

Some chips have flash and psram embedded inside the same package. It is one chip with multiple dies inside. A module like ESP32-S2-WROVER has separate chips for esp32-s2, flash, and psram on a small pcb. So ESP32-S2-WROVER does have flash and psram but it is not considered embedded flash.
