Yes, microSD cards can be accessed in UIFlow or with MicroPython. They allow you to read and write data from/to the microSD card, enabling storage and retrieval of information on compatible devices.

ok......

now even one simple uos.mountsd() also works...
good...

>>> import uos
>>> uos.mountsd()

Here I attach the webpages which helps me mostly.
Hope it can help other people.

Funny...

I re-burned back to UIFlow-v1.2.3, and it also worked.

>>> import uos
>>> uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4)
>>> uos.mountsd()

@ajb2k3

thank you.

I went to MicroPython.org but found nothing helpful.
Finally, I erased the firmware and burned the M5S with the UIFlow-v1.3.1-Beta firmware.

It worked, with the code below.

>>> import uos
>>> uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4)
I (53596) gpio: GPIO[23]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pull             down: 0| Intr:0
I (53596) gpio: GPIO[19]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pull             down: 0| Intr:0
I (53604) gpio: GPIO[18]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 1| Pull             down: 0| Intr:0
>>> uos.mountsd()

@ajb2k3

I just exec in REPL.

import os
os.mountsd()

nothing else....

I also tried os.SDMODE_4LINE, os.SDMODE_1LINE and os.SDMODE_SPI with os.sdconfig(...) before mountsd(), but none of them worked.

Forgot to say, I'm using M5Stack Fire.

You also need the machine, sdcard and dpi library imported. That’s why I recommend that you visit MicroPython.org

@lukasmaximus
thank you for your reply.
But when I tried to exec os.mountsd I got an error as below.

os.mountsd()
W (20141) sdspi_host: spi bus changed (1 -> 2)
E (20141) sdspi_host: spi bus 2 not available
E (20141) vfs_native: Failed to initialize SDcard (258).
Traceback (most recent call last):
File "", line 1, in
OSError: [Errno 5] EIO

Can you post all you code please

Not possible in uiflow yet. Micropython is easy
import os
os.mountsd()
os.listdir('/sd')

etc...

Take a look at the micro python official forums, there is a discussion about it
