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?

Same here..MDBT42Q, 2v09
```
>require("Storage").list()
=[  ]
>require("Storage").getFree();
=40960
>process.memory();
={ free: 2458, usage: 42, total: 2500, history: 17,
  gc: 0, gctime: 3.47900390625, blocksize: 16, stackEndAddress: 536928976, flash_start: 0,
  flash_binary_end: 432868, flash_code_start: 442368, flash_length: 524288 }

```
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.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
