Description
Attempts to mount a LittleFS filesystem fails on ESP32-C3...
I am using the FS read PR (#6569) as well.
LittleFS configuration settings:
[LittleFS] data : /Users/brent/Downloads/esp32_esp8266_test_littlefs/data
[LittleFS] offset : 0
[LittleFS] start : 2686976
[LittleFS] size : 1472
[LittleFS] page : 256
[LittleFS] block : 4096
->/secrets.json
[LittleFS] upload : /var/folders/k6/g066g1tn567fn8mj2p42x4240000gn/T/arduino_build_941002/esp32_esp8266_test_littlefs.littlefs.bin
[LittleFS] address: 2686976
[LittleFS] port : /dev/cu.usbmodem1433301
[LittleFS] speed : 115200
[LittleFS] mode : dout
[LittleFS] freq : 80m
Sketch
/* Checks and writes out the files on a LittleFS filesystem on ESP8266 and ESP32 platforms
This sketch only performs READ operations on the LittleFS filesystem and should not modify the filesystem's contents.
NOTE: The LittleFS image must have already been uploaded prior to using this sketch.
