I Have problem with Sd card in my first batch M5Paper, I try this code but don't works, anyone can try in it's m5paper?

#include <M5EPD.h>
File myFile;
void setup(void)
{
M5.begin();
Serial.begin(115200);
SPI.begin(14, 13, 12, 4);
bool ret = SD.begin(4, SPI, 20000000);
if(ret == false)
Serial.print("SD ERROR...\n");
else
{
Serial.print("SD OK...\n");
if (SD.exists("screen.txt"))
Serial.print("screen.txt exists...\n");
else
Serial.print("screen.txt NOT exists...\n");
Serial.print("Try to create screen.txt...\n");
myFile = SD.open("screen.txt", FILE_WRITE);
myFile.println("Some text...");
myFile.close();
if (SD.exists("screen.txt"))
Serial.print("now screen.txt exists...\n");
else
Serial.print("not jet screen.txt exists...\n");

There are two version of M5Stack Fire?
I recently buy a Fire with MPU6050+MAG3110 instead of MPU9250
MPU6050 are old version?

@watson one question, are you sure weight unit are I2C?
I see the back and report GPIO A/B/C...
I buy also this:

And I hope this works...
