ESPtool command to return Memory on ESP32 DevKit?

Postby Fran_iii » Tue May 04, 2021 12:13 am

What is the ESPtool command entry to return how much memory... ram, sram, flash memory, etc is on the Espressif ESP32 DevKit V4 board?

I just got ESPtool installed on a Win10 PC and a Linux Mint 20 machine and am learning how to use it.

From the command line I know...
> esptool.py --help
and...
>esptool.py chip_id

But I'm having trouble understanding all the
> esptool.py --help
results.

Thanks for any help.
