Hello @romor001

I've just retested it on my M5Stack Fire running UiFlow v1.9.1-fire firmware and I can list the content of the SD card just fine.
Blockly code:


Micropython code:

from m5stack import * from m5ui import * from uiflow import * import os setScreenColor(0x222222) print(os.listdir('/sd/'))

Make sure the SD card is inserted before you power the M5Stack Fire as it is mounted while booting up (mounting code is in boot.py). In the log you'll see this:

SD card mounted at "/sd"
