Files cannot be opened for writing after some time #3504

Closed davidk88 closed 7 years ago

Hardware

Hardware: ESP-12E Core Version: 2.3.0-rc2

Description

I'm writing some data into files every 10s. After some time files cannot be opened for writing ("w") anymore (it can be opened for reading). Problem persists until I upload filesystem again.

I also tried with lastest git version, but result is the same.

Thanks in advance

Settings in IDE

Module: ESP-12E Flash Size: 1MB/4MB CPU Frequency: 80Mhz Upload Using: SERIAL

Please add a minimalist sketch to reproduce the issue.

I ran simple sketch which writes to a file every second and that is fine. In my app where I have problems, it looks like that there is a problem with (low?) memory and then filesystem gets corrupted. This is Exception I get:

You shouldn't be using 2.3.0-rc2, it's ancient. You should use 2.3.0 stable, or better yet: latest git.

Be aware of: Max stack size for the ESP is 4KB (or 5, I can never get the straight of that). Using the stack is very good for reducing heap fragmentation, but if you go over the stack size limit you'll have memory corruption. If you have a huge object on the stack, try creating it dynamically with new (preferably into a smart pointer). Don't declare huge strings as just const char *. Strings like that are stored in RAM. Instead, (ab)use F and PROGMEM. Especially don't init arduino String objects like so: String blah = "some huge ass string that never ends zomg like those used for static html content which is a Bad Idea on the ESP so don't do it"; If you are serving static html, store it in a file on the SPIFFS and let the webserver stream it. Any dynamic content can be served as tiny jsons or some other key=value pair format or w/e, and applied to the html doc via js on the browser side. A js is another static file on the SPIFFS. Beware your power supply, trust nothing. When in doubt, go big and heavy for testing. I used a 5V 20A DC/DC converter, powered from a 200W AC/DC converter. This proved to me that some DC power supplies that claim 1A or 2A like those used for cell phones are in fact crap, and not enough for the ESP. That includes some iphone power adapter clones. You code that executes in the loop() can't be of arbitrary duration. If you take too long, the wifi stack will wind up and the buffers will overrun. You can remedy the situation somewhat byof seeding with yield() calls, but that helps only in cases of wiffi traffic not addressed to the ESP. Keep your code small, seed itnwith ith yield calls, break it up into a state machine to execute in small pieces if nothing else else works.

Please close this issue, adjust your design, instrument your mem usage everywhere, and open a new one if you are sure there is a specific issue that can be addressed.
