Platformio Build Error - no matching function for call to 'LITTLEFSImpl::open

[crashmatt]

Describe the bug

Mismatching parameters on call to LITTLEFSImpl::open in LITTLEFS.cpp causes failure to build

Steps to Reproduce

Create empty project/folder Create main with empty setup and loop and basic Use PIO Home to search for and add ESPAsync_WiFiManager Build

Have tested with a code samples and empty main with basic includes. Tested with different filesystems defined in platformio.ini Tested with different filesystems defined main

Expected behavior

To build

Actual behavior

Build error:

.pio/libdeps/esp32dev/LittleFS_esp32/src/LITTLEFS.cpp:44:28: error: no matching function for call to 'LITTLEFSImpl::open(const char*&, const char [2])'

Debug and AT-command log (if applicable)

Found the error in LITTLEFS issues: https://github.com/lorol/LITTLEFS/issues/43

[khoih-prog]

It's better to use the new ESP32 core v1.0.6+, such as ESP32 core v2.0.3 in PIO.

The lorol's LITTLEFS library has been deprecated and I'm afraid won't be updated to fix that bug.

Yes. I figured out that I should use SPIFFS. Trying to learn too many things at the same time. Thanks for the response. /Matt
