What is the `factory` partition used for? How much flash space does the Espruino engine take?

On the Espruino ESP32 page , it says the factory partition is for the initial Espruino firmware.

And on the FAQ page it says

Espruino uses between 100kb and 200kb of Flash,

But the esptool.py says it actually takes around 1.33 MB instead of 200 KB when I flash the firmware to ESP32.
```
Wrote 1397712 bytes (903419 compressed) at 0x00010000 in 12.3 seconds (effective 907.6 kbit/s)...
```
My question is:
Does the factory partition also include ESP32 firmwares and other underlying drivers utilized by Espruino? If that's true, is it possible to get the exact flash space used by Espruino engine itself?

Well ESP32 docs need to be updated.

have a look here

At the moment it is taken 1397712 bytes and is stored in partition named factory.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
