The board ran for months, but someday the codes in flash disappeared, and the board died.
How and Where I can figure out the key problem?

What board are you using? Is it still running Espruino, it's just that there's nothing listed by require("Storage").list() any more?

={ free: 2458, usage: 42, total: 2500, history: 17,
  gc: 0, gctime: 3.47900390625, blocksize: 16, stackEndAddress: 536928976, flash_start: 0,

I can connect to the device, but I don’t want to do anything else with it until there’s a suggestion.
The power supply was continuous and i use a good quality adapter, voltage regulator and battery. I was able to connect to the device, I didn’t have to reboot, but the flash was completely empty. I used the flash to log in, but that couldn't be much data.
