NOT replicated on Feather M0 Adalogger! The above code works without error (Class 10 Sandisk card).

[tannewt]

This error can occur if the card isn't formatted. fabitencourt, does it work when connecting to a computer or in Arduino?

[fabitencourt]

The black Verbatim 16 G one wasn't formatted. I've formatted fat32 with gparted and still the same errors on the same places. After many trials finally the black lexar 16G worked one shot. I'm happy...

Just saw the blue 16G on gparted and it had a 4 M not allowed. I've formatted on fat 32. I'll try with that too. No way. The only one is that Verbatin 16G black card you see on the photo. Lexar doesn't seems to work at all. Even if they work on arduino sketches.

[fabitencourt]

No way. Neither of Lexar cards are working. The black 4G and the blue 16 G too. Both Lexar cards don't seems to work for now.

[tannewt]

Did you get it working with a different card? I ended up with a Kodak card instead of Lexar but I'll give it a try today.

[tannewt]

I believe I'm seeing the same thing with a Samsung EVO Select card. It works with my Mac via card reader but produces an OSError 19 in CircuitPython. Looking at it now.

[fabitencourt]

I've downloaded the new version, candidate 2. I'll try it as soon as I can. I've noticed the DS3231 library is already there. Perfect. I'll give a try.

[tannewt]

@fabitencourt can you please try this mpy (after unzipping)? Its for CircuitPython 2.x. What I found was that the Samsung cards I have don't like the chip select deinit and extra clocks between the read command response and the actual data.

The fix is in this pull request.

adafruit_sdcard.mpy.zip

[fabitencourt]

OK Scott, I just tried that version and it's not working better for me, even my verbatim 16 G that worked well before got stuck on:
sdcard = adafruit_sdcard.SDCard(spi, cs)
Traceback (most recent call last):
File "", line 1, in
File "libraries/drivers/sdcard/adafruit_sdcard.py", line 84, in init
File "libraries/drivers/sdcard/adafruit_sdcard.py", line 117, in _init_card
File "libraries/drivers/sdcard/adafruit_sdcard.py", line 172, in _init_card_v2
OSError: timeout waiting for v2 card

I've tried the last bundle candidate 2 and even if my Lexar doesn't work any better my verbatim 16G works like a charm. So I prefer the adafruit_sdcard.mpy from candidate 2 bundle.

[tannewt]

No rush! Thanks for the quick reply.

[jerryneedell]

@tannewt FYI - I am able to access a SanDisk 8GByte Class 10 card from my M0-Express via an Adalogger Featherwing. Using latest 2.0.0 and library bundle

[tannewt]

Ok! Thanks for the report @fabitencourt. I will buy some more cards off of Amazon. I expected the newer library to work better. Perhaps they are even pickier about the chip select line. The arduino library is also much faster in talking with the chips.

[fabitencourt]

In my opinion the new library adafruit_sdcard.mpy from bundle candidate 2 is the best I've used. But still doesn't work with my Lexar cards. But they work very well with my sandisk 16G card. That's the one I'll use. Now I will try the DS3231 library. That's essential to my logger project. It's all like Christmas gifts all around....📦🍾🎁👍 2017-09-10 12:54 GMT-04:00 Scott Shawcroft <notifications@github.com>:

Is anyone able to send the exact product description for an SD card that they have working with CircuitPython? Preferably 32GB or bigger. I'd like to order a card that is known to work. Thanks!

[fabitencourt]

In my opinion you're missing some files on circuitpy's directory. Personally mine is like this and is working with a 16 G Verbatim card...

Have you formatted your card fat32 ?

[cehiles]

The necessary libraries are in the /lib folder. However, I reformatted Fat32 using gparted and that got things working. Thank you!

[fabitencourt]

My pleasure. Really glad to know it. That's exactly what happened in my case. Error 19 seems to mean: "card not formatted" and I've used gparted too.

[tannewt]

@cehiles glad that worked!

Ok, I've ordered Transcend, Verbatim and Lexar cards to test with. @meichr could you post a picture of the cards? I think I've tested a similar Samsung card and it worked ok.

My test cards so far:

[meichr]

@tannewt I've done the above tests with the library-2.0.0 bundle from Sep. 15th and thought that it already contained the above update from Sep 9th. My error!
The pictured SanDisk sd card works with the Sep. 15th version and the above Sep. 9th version. The Transcend sd cards and the Samsung sd card work with the above Sep. 9th version, but not with the bundled Sep. 15th version.

These cards work with the above Sep. 9th library update.

[tannewt]

Wups, looks like I forgot to request a review from @dhalbert on it! The fix is here: adafruit/Adafruit_CircuitPython_SD#1

[meichr]

But I forgot to thank you for the fixes :-) .
