Hi @meron1122! Which example do you want to try with Arduino or SDK?

[meron1122]

For example, i want to extend spiffs size.
I use arduino.

Default 16MB linker script has 15MB spiffs partition, is it enough for you?
Just add to your environment in platformio.ini next line:

build_flags = -Wl,-T"esp8266.flash.16m.ld"

Thanks i think this solved my issue, but, by the way, Do you have any link, to read about this mapping scripts? ;)

I haven't seen an extensive manual, but there is some information about this topic in the Arduino issues, for example here.

Thanks @valeros I quickly looked at that earlier today but I have to confess it didn't mean much to me.
