I have a weird problem.
I have a config file '/config.json' which I'm storing in a LittleFS filesystem. If I upload the firmware, then the first time it reads the file. If I reset or power off and on then LittleFS.open('/config.json') returns false. If I re-upload the code it finds the file again!
I'm confused.
ok it looks like a memory issue.
I'm also using painlessmesh and if I remove the call to mesh.initOTAReceive("role") then reading from the FS works again.
Final update. I changed the flash layout from eagle.flash.4m1m.ld to eagle.flash.4m2m.ld and now mesh.initOTAReceive doesn't kill the FS.
