Pico problem with EEPROM Lib

[Kucky]

Hey,
i'm new in this forum. I´am 66 year old and pensioner. I've done a few small Arduino projects. This is my first Pico Project. I want to use the EEPROM Lib from "earlephilhower". If i compile the example "eeprom_write" i get this message
"lib\EEPROM\EEPROM.cpp:121:5: error: 'rp2040' was not declared in this scope"
in line
" rp2040.idleOtherCore();"

Can anyone help me?

I using PlatformIO with C++

Best regards
Willi

I've got exactly the same problem.

Maybe contact the author, raise an issue ...

https://github.com/earlephilhower/ardui ... EEPROM.cpp

I have never used C++ but would guess 'rp2040' is some kind of global reference, object or namespace, and something needs to be done to provide that. I have no idea what.

What are you trying to use that library for? If it is to erase flash there is a Raspberry Pi created flash_nuke.uf2 file for that (and on github)

The EEPROM library from the community Arduino code can not be run in MBED Arduino. I think that is your problem. You have to use the full install from https://github.com/earlephilhower/arduino-pico

I've built in synthetic EEPROM (uses 4K of flash instead) and because the RP2040 can't write to flash while executing from it, the other core needs to be halted. My code has this `rp2040` class which handles this and other RP2040-specific things. The examples are also built as part of every pull request and release, so I'm quite sure they do build (again, only with the community core).

Also, @hippy is right. The best place to ask for help w/the code is the GitHub pages, not a general Raspberry Pi forum. I don't often check here, sorry.

Thanks at all.
I will post in the recommended forum.
