@perryc:
Can you somehow share your code? I can not send you a pm (it seems that this is blocked for new users; why?)

How to use virtual file system.?
Re: How to use virtual file system.?
I have it working now, works very well, reading and writing a file to flash.
I am using it with ardunio and had to increase the task stack to run the espidf vfs_fat example.
Should be able to compile the wear leveling code example and add the custom file partition for the filesystem and it will work.

Interesting.
How was it done?

Take a look at: viewtopic.php?f=18&t=1901jgfrmesp wrote:Yes, that precisely the case. Spiffs raw (so without vfs) works fine.
As soon as I use the vfs part (I used the code at https://github.com/nkolban/esp32-snippe ... vfs/spiffs)m I can not read the file back (I can not see if it is written in the first place).
Best,

Re: How to use virtual file system.?
Hello, I'm new on ESP32 ( have only little experience in programming) and currently working on a simple webserver. ESP starts in AP-mode.
I hope to find a solution for the following issue and kindly ask for help:
I would like to load a file that contains my html-code.
I tried to simply use the FS.h library and the code that was used on ESP8266 since I could not find a reference guide for the ESP32 libraries that i undestood.
I compiled in Arduino IDE and also PlatformIO.
In Arduino I used the library from espressif github https://github.com/espressif/arduino-esp32
Error is: " 'SPIFFS' was not declared in this scope "
Heres the important part of my code:

Re: How to use virtual file system.?
Sorry for slow reply jgfrmesp - I'd not seen this thread was still active. Is there any reason we'd not want to move on to using the wear leveling driver that's now in the esp-idf? So far it's been working well in my tests other than I've not solved how to flash a prebuilt filesystem.
