SDCard does not work on M5Stack FIRE.

    Hello, thanks for your comment, I have it formatted with FAT32.
    I think the problem is that the / sd drive is not mounted.
    I am testing with the following code:

    from m5stack import *
    from m5ui import *
    from uiflow import *

    setScreenColor(0x222222)

    with open('/sd/test.txt', 'w+') as fs:
          fs.write('Hello World')

    And it gives me the following error: OSError: [Errno 19] ENODEV

    @gaviota I am thinking that it is a problem with the firmware version v1.7.1 of the M5Stack FIRE.

    @gaviota I have tried the following and it gives me error:

    from m5stack import *
    from m5ui import *
    from uiflow import *
    import os
    sd_mount()

    Try use the sd with the UIFlow IDE

  • Hello @fraramon

    the following micropython code works for me with a 16GB SD card and running UIFlow firmware 1.7.1.

    from m5stack import *
from m5ui import *
from uiflow import *

setScreenColor(0x222222)

label0 = M5TextBox(34, 41, "Text", lcd.FONT_Default, 0xFFFFFF, rotate=0)

with open('/sd/test123.txt', 'w+') as fs:
  fs.write('Hello World')
with open('/sd/test123.txt', 'r') as fs:
  label0.setText(str(fs.read()))

    BTW: Please make sure your SD card, when inserted, is completely in and flush with the case and doesn't stick out. I am mentioning that because I also have an M5Stack Gray which has a broken SD card slot in the sense that the SD card, when inserted, still sticks out a little bit and that makes the SD card fail as the pins do not make proper contact. Maybe your M5Stack Fire has a similar issue.

    Thanks

    Hello, thank you very much for your answers, I have tried from UIFlow and it has not worked for me, and then I have tried with the code that @felmue has sent me and it does not work either, it returns the error code "OSError: [Errno 19] ENODEV" .
    I am beginning to think that it is a problem with Firmware 1.7.1 for M5Stack FIRE or Hardware of M5Stack FIRE.
    I have tested the card on other devices and it works without problems. It is formatted with FAT32 and has 16GB.

  • Hello @fraramon

    sorry to hear. I am afraid I am out of ideas at this point. Sorry.

    Thanks

    Thanks for your support @felmue, today I received my new M5Stack CORE2 and the SD card was immediately, so the card is not the problem, the problem is the fire M5Stack FIRE that has a problem. I have verified the great quality that CORE2 has, the truth is that it is very very good. I'm going to do more tests to see how it works.
