SPIFFS: mount failed in restful_server example (IDFGH-1841)

[derek-denman]

Environment

• Development Kit: ESP32 Wrover Dev Board from Analog Lamb
• Module or chip used: ESP32-WROVER-B
• IDF version: v4.1-dev-141-ga7e8d87d3
• Build System: Make
• Compiler version: xtensa-esp32-elf-gcc (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a) 5.2.0
• Operating System: macOS
• Power Supply: USB

Problem Description

Expected Behavior

It is expected the the program works as described in the example readme

Actual Behavior

After the ESP32 connects to the WiFi network I get the following error

E (4526) SPIFFS: mount failed, -10025
E (4526) example: Failed to mount or format filesystem

Steps to reproduce

1. Run make menuconfig
2. Set Website deploy mode to Deploy website to SPI Nor Flash
3. Setup Example Connection Configuration to use WiFi network
4. Run make erase_flash flash monitor -j4
5. After the ESP32 connects to the WiFi network I get the following error

E (4526) SPIFFS: mount failed, -10025
E (4526) example: Failed to mount or format filesystem

Code to reproduce this issue

Example code has not been modified

I've changed this line to .format_if_mount_failed = true

esp_rest_main.c

However, it cannot read the files:

@derek-whisper @fernandosalomao Thanks for reporting this. The issue is that SPIFFS filesystem image wasn't flashed to the board when running make flash. The fix is in review and will be merged soon. For now, you can apply the following change locally:
