a flash code bug

[L-jasmine]

I want to read config file on wifi_kit_8 `#include "FS.h"

bool loadConfig() { File configFile = SPIFFS.open("/config.json", "r"); if (!configFile) { Serial.println("Failed to open config file"); return false; }

String data = configFile.readString();

Serial.print("data: "); Serial.println(data); return true; }

void setup() { Serial.begin(115200); Serial.println(""); delay(1000); Serial.println("Mounting FS...");

if (!SPIFFS.begin()) { Serial.println("Failed to mount file system"); return; }

if (!loadConfig()) { Serial.println("Failed to load config"); } else { Serial.println("Config loaded"); } }

void loop() { }`

bug: Arduino:1.8.8 (Windows 8), 开发板："WiFi_Kit_8, 80 MHz, Flash, 4M (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"
