cannot load eeprom information at boot #227

Hello again all of you. I restarting doing some dev on Wled, (I want to implement the KNX protocol, but this issue is unrelated). When compiling from the source with the arduino IDE (1.8.10), wled cannot load eeprom settings see debug info at the end of the message. Fortunately, it read correctly if flashed using the bin provided I understand it is a problem from my dev environment but I cannot ( yet ) pinpoint the issue. If any of you had it, please reply. otherwise I will update with the solution once found.

Best regards to all the team

completely unrelated to WLED, It also does this with an older arduino IDE and basic eeprom sketch.

an issue has been opened to the esp8266 for arduino maintainer: https://github.com/esp8266/Arduino/issues/6551

For your information since esp8266 core 2.5.1 writing to the eeprom is randomize over all the flash to minimize wear.

This imply that when using eeprom, the size of flash set in your IDE is CRUCIAL. I used a 4MB settings with a 2MB board (and this information was difficult to find).

Please always try with lowest memory settings (1M)
