[Platformio] Linker, how to reserve 4 pages of 4k for EEPROM emulation

[hitech95]

I have an application were i have to write some data in the emulated eeprom.
I woulld implement a simple wear leveling algorythm.

To do so I need some 4k pages to rotate the writes to.
I've seen that there is a _EEPROM_start variable in the linker but I've not figured out how this is configured.

Any suggestion?

You're going to need to edit the boards.txt file where XXX>build.eeprom_start is defined (you'll need to change fs_end too if you want to use LittleFS.

At the end I'm using the little FS range for my EEPROM emulation. I've seen that the 4096 EEPROM size is hard coded in a lot of places. Since I don't need LittleFs I'm just using it's handy configuration. Only "downside" I'm wasting 4k of flash.
