kc868-a6 A fatal error occurred: MD5 of file does not match data in flash!

[Siebje]

Hi,

currently, I'm working with the kc868-a6, for the last couple of weeks I've used the board with success! 

since the beginning of this week, problems started to reel in, when I was reading out analog inputs from my board. This is my code with the corresponding error code:

Code:

#include "Arduino.h"

#define ANALOG_A1 35

void setup() {

Serial.begin(9600);

pinMode(ANALOG_A1, INPUT);

}

void loop() {

Serial.println(analogRead(ANALOG_A1));

delay(500);

}

Code:

Writing at 0x0000e000... (100 %)

MD5 of 0xFF is 84d04c9d6cc8ef35bf825d51a5277699

A fatal error occurred: MD5 of file does not match data in flash!
Failed uploading: uploading error: exit status 2

I have tried many things to fix it but all without success. hopefully, there is someone who can help me with my problem

Thanks in advance!
