13.1 DEV - corrupted FS, and problems to load presets

[dosipod]

What happened?

Using https://wled-install.github.io/ to install [SR13.1 DEV] results in corrupted FS . Using the same installer with normal wled is working fine . The same was tested on multiple esp32 versions .When saving presets serial monitor shows errors with LittleFS

To Reproduce Bug

Use https://wled-install.github.io/ to install 13.1 DEV . Then create presets and reboot the esp, look at the serial monitor in ardunio IDE , you should see an error related to LittleFS

Expected Behavior

As we are using the same installation method we expect srwled fs to be fixed

Install Method

Binary from WLED.me

What version of WLED?

13.1 DEV

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

No response

SR13.1 DEV binary is only here https://wled-install.github.io/ , is this web installer not supported ?
I am only testing multiple units and if you can install SR13.1 DEV from https://wled-install.github.io/ without any issue then we can close this .

not sure if this is related, but I observed that after upgrading to 13.1 my presets stopped working.

• presets where still there
• selecting a preset resulted in a red error message in the web-interface along the lines "connection to wled lost" each time.
• everything else (except analog microphone Analog Microphone not working in 0.13.0-b6 (worked in 0.13.0-b4) #162 ) worked fine

downgrading to 12.0 made presets work again.

@btittelbach just compiled 13.1 from the Master branch myself and yes presets stopped working. Most of the time selecting a preset does not change the animation and sometimes the esp32 resets itself.

[softhack007]

What kind of micophone are you using? Analogue or digital? Which Pins?

Because there could be a relation to how the I2S driver is collecting samples, like watchdog reset or "WiFi dies" effects...
Also corrupted FS might be a consequence of a reset/crash, if this happens while a write operation is ongoing.

[dosipod]

I am not sure if this is clear but we are testing multiple units and none of them are having any attached leds or microphone .
Compiling from source and flashing with esptool as per the wiki also resulted in the same LittleFS behavior . Is it possible that this is related to my setup and not a bug ?
It is still the case there is no issue with compiling or installing normal wled from web installers on the same PC

[softhack007]

Did you check serial output? In case you see some "guru meditation" or unexpected reset, that would be clearly a bug.

[dosipod]

I am not really sure if the first picture I added is what you meant by check serial output because that is the serial output errors but i am not sure if that is generic for all filesystem issues or it is pointing to something in the code in lfs.c .

It would be very simple to close this if someone could mention that installing SR13.1 DEV from https://wled-install.github.io/ worked with no filesystem errors and give few details on their environment if esptool installed version even matters in such case .

[softhack007]

It seems that LittleFS has a known problem when used from multiple threads (missing semaphore). As consequence, you see bad blocks and temporary missing files. Maybe related ?

[softhack007]

... I have created a fork of lorol LittleFS, and merged the pending PR that should improve thread-safety.
Please give it a try - you need to re-compile with the following change in platformio.ini:

find this in [esp32] section:

https://github.com/lorol/LITTLEFS.git

and replace with

https://github.com/softhack007/LITTLEFS-threadsafe.git#master

Please tell us if this helps.

[dosipod]

Thank you very much , Would it be possible to replace the bad 13,1 Dev bin at https://wled-install.github.io/

[softhack007]

I've just committed the necessary changes for platformio.ini into dev - see 212e2d3

Now we need someone who knows how to upload binaries to wled-install....

[dosipod]

we just tested https://github.com/wled-install/wled-install.github.io/blob/main/fw/SR_ESP32_4MB_13.1_DEV.bin [07d7dec]
on 3 different MCUs ( All of which worked fine with normal wled and SR13.0-B6 ) .

All our tests indicated the presets issues are not resolved . Flashing the bin per the wiki using esptool ,OTA or from web installer resulted in the same issues with presets .

[jonasschwenk]

Same here. With SR 13 b6 everything works fine. After Upgrade to 13.1 presets are broken. No matter if installed ota or flash via esptool( inc erase ).

[softhack007]

Some known problems in WLED that could be related to the presets problem:

• SyntaxError: Unexpected token in JSON at position 3063 Aircoookie/WLED#1981
• crude hack in presets.cpp Aircoookie/WLED#2681

The first problem affects the B6 prerelease, and could lead to corrupted json files that cannot be loaded in a newer version of WLED. The second one affects WLED 13.1 only, and could lead to presets not being loaded/saved.

Could you please post your your [WLED-IP]/presets.json files, before and after updating WLED? It might help us poor free-time devs to better understand what happens on the devices.

[dosipod]

Good News, Members of the SR dev team are able to reproduce the presets issues with 13.1 Dev.

[ewoudwijma]

Softhack solved the preset issue. Can you confirm it is working for you?
I don't know status of corrupted FS, do we need to keep this issue open?

[dosipod]

We could only spare two units at the moment with 16x32 and 16x16 . We did not face any corrupted FS when interacting with presets . Aside from few minor unrelated observations it seems the installation issue reported earlier for 13.1 is solved . Excellent work . I can close this if someone else confirms or at your discretion .

[jonasschwenk]

I can also confirm its working for my setup. All 8 controller are now working with 13.1. All proplems with the presets are gone. Excellent work and a big thank you.
