Cardputer SD-Card issues / how to format?
-
Hello,
it's a really fun device, but I somehow struggle to get the SD-card working…
Tried Uniflow2.0 and it all works - except the SD.
No matter what I try, I always get:
Traceback (most recent call last):
File "<stdin>", line 74, in <module>
File "<stdin>", line 47, in loop
OSError: [Errno 19] ENODEVUsing the CLI:
>>> os.listdir("/")
['system', 'flash']So the SD isn't seen.
I tried formating on OSX, OSX (Terminal), in Win10, Fat16 / FAT 32.
Both with a 8GB Card and two small 128MB cards.Is there a known good sample sketch to handle the SD in Cardputer to format / get Infos?
I am using PIO, but I guess that can broadly be be considered "Arduino IDE"?

What code are you using?

What code are you using?
Basically just UIFlow2 > SDCard > listdir
Or the CLI in UIFlow for the os.listdir()

Hello @Brainzilla
try adding the
Init SDCard with
block before accessing the SD card. See below.Thanks

it seems that there is something happening.
#1 Started with card
File "<stdin>", line 18, in <module>
File "<stdin>", line 11, in setup
OSError: [Errno 22] EINVAL#2 Removing the card
File "<stdin>", line 18, in <module>
File "<stdin>", line 9, in setup
File "hardware/sdcard.py", line 19, in SDCard
OSError: [Errno 116] ETIMEDOUT: ESP_ERR_TIMEOUT#3 Running it again
File "<stdin>", line 18, in <module>
File "<stdin>", line 9, in setup
File "hardware/sdcard.py", line 16, in SDCard
OSError: (-259, 'ESP_ERR_INVALID_STATE')Inserting the card back at runtime changes the error back to #1
Pretty sure the solution lies somewhere in correctly formatting the card.
That's why I would like to format it with the ESP itself.

OK, it works now.
Seems there was a <space> in the "empty" listdir path facepalmAnd it does require the SD card init block as you suggested.
I thought that would be included in the "init built-in hardware" step, but the code shows otherwise.Even hot-swapping multiple works – neat.
Thank you so much!
