Description

It seems as if LittleFS is compiled with debug macros enabled so it will pollute the serial output of any program. I do not think it can be switched off at runtime.

Debug Message

./components/esp_littlefs/src/littlefs/lfs.c:2246:debug: Relocating {0x2f, 0x2e} -> {0x79f, 0x2f}

Possibly wrong repository. This is IDF functionality. Are you seeing LFS debug messages in Arduino projects?

That message is printed if LFS_DEBUG is defined in lfs_util.h. The only thing this repository might be able to control is defining LFS_NO_DEBUG.

Are you seeing LFS debug messages in Arduino projects?

yes, that's the point.

I was confused by the ./components/esp_littlefs path as well and looked into IDF source first to report the issue there, but could not find it anythere in the repo. I assume it must be in some code Arduino CORE pulls in from elsewhere.

As this component is pre-compiled into tools/sdk/esp32/lib/libesp_littlefs.a it is something to be fixed in the build of that library I guess.

The .a files (and config options) are built here: https://github.com/espressif/esp32-arduino-lib-builder

Hmmm. I have a local copy of IDF 4.4.3 on my computer, but I can't find the "components\esp_littlefs" in the IDF repository. I did notice that SPIFFS (which I use) uses ESP_LOGE() macros for debug statements vs printf in LittleFS. I believe the Arduino compile turns those off ESP_LOGE(), which is why they aren't an issue. This looks like an issue that IDF should solve: https://github.com/espressif/esp-idf. Odd though that LittleFS has disappeared....

This implies LFS may be a separate component now: espressif/esp-idf#5469

LittleFS is added as an additional component in lib-builder. Open a similar issue there so they can track it.

@mrengineer7777 thanks for archeological work! ;-) I opened an issue here: espressif/esp32-arduino-lib-builder#103

Fixed in repo LittleFS
