ESP8266 - Parameters Overwritten by LittleFS Upload Filesystem

[JoJos1220]

Hello everyone,

i got an issue i want to share with you and maybe someone can help me with that problem.
In a project i use ESP8266-01M. I want to access some parameters of the project by webserver which are saved by the preferences.h libary into the nvs. Actually, the project works fine - but now i got an issue, that my with preferences.h defined parameters are not saved after a power on cycle after i loaded the full sketch + filesystem image LittleFS to the esp8266 by platformio. If i load only the sketch - the parameters are successfully saved after power on cycle. If i add the filesystem image the parameters are only reading "0" - or better to say nothing....

I tried the sketch also on a esp12-f with an additional linker script board_build.ldscript = eagle.flash.2m512.ld which is working great - even if i add to the skecth the filesystem. But if i change back to the original one it is not working any more. The original linker script i use is: board_build.ldscript = eagle.flash.1m64.ld which should acuallty work fine because my sketch size is about 58% of rom (data from PlatformIO build) and the filesystemdata is 44kB which should be also fine.

Someone has an idea why it is not working in the "original" configuration?
