Hi, great project, just what i have ben looking for! but i have a problem when linking the .elf file at the very end. do you have any ideas?

it looks like all undefined reference errors. it is because the ESP32 does not have eeprom, but flash? I am using an ESP32-S3 (have tried others as well), and platform.io. i get the following errors (edited for size): it looks like all undefined reference errors. it is because the ESP32 does not have eeprom, but flash?

so it looks like i was using an older file or CO_config.h which had the storage set to 0x01. now i can compile!
