Problem Description
I have several ESP-12F and ESP-12S.
The sketch works fine on ESP-12F but crash on ESP-12S (I have testes at least 5 different units.
Problem is similar to the one reported on 4061
Attached a picture of flash, just in case is same problem.
On instruction SPIFFS.begin(); it crash.
Any ideas?
Thanks!!!
#include "FS.h"
String realSize = String(ESP.getFlashChipRealSize());
String ideSize = String(ESP.getFlashChipSize());
bool flashCorrectlyConfigured = realSize.equals(ideSize);
void setup() {
Serial.begin(9600);
Serial.println("Starting...");
if(flashCorrectlyConfigured){
Serial.println("flash correctly configured, SPIFFS started, IDE size: " + ideSize + ", real size: " + realSize);
SPIFFS.begin();
Serial.println("After begin...");
}
}
void loop() {
}
