ESP8266 Flash Size: 4MB (FS:3.5MB OTA:~256KB)

Hello masters, how to make Flash Size: 4MB (FS:3.5MB OTA:~256KB) ?
Thanks.

Without any guaranteed result, you can try and play:

• Find boards.txt.py in your filesystem
• Edit it and add f4m.update( flash_map( 4*1024, nnn)) (nnn>3072?)
• Regenerate configuration
• Try

Thank you for your replay, I'm using Arduino 1.8.19, and can't find the boards.txt.py file, haha.

I want to upload a file size of 3.00 MB (3,153,920 bytes) is it possible?

It is there.

If your file is an html file, then you can compress it with gzip -9 and call it .html.gz instead of .html.

Otherwise, you can try again and find the above file (boards.txt.py) and have a try.
