SD lib w/ card 'flakey'?

[ladyada]

heya im using known good hardware, with pullups on the SD CS line, no level shifters, PCB traces not jumpers - but getting 'flakiness' on init/mount

[E][sd_diskio.cpp:99] sdSelectCard(): timeout
[E][sd_diskio.cpp:708] sdcard_mount(): f_mount failed 0x(3)
Card Mount Failed

oddly, it works maybe 10% of the time. once it starts working, it 'keeps' working until a full power reset. if it doesn't work, sometimes hitting software reset helps, but usually not. this is with the SPI library - tried changing SPI speed in SD.begin() without any noticable changes. still investigating ... but making a note here in case others can reproduce

fyi, grabbing the non-optimized SD library works great with no hiccups - https://github.com/adafruit/arduino-esp32/tree/d602169ebcd126c309009e87c1e455f2c892d08f (yeah sorry it got smooshed in the upstream merge so please download the zip from that point to get the library files)

[me-no-dev]

Hm that is rather strange. I had gazillion of issues with SD_MMC and pullups but none with SD. I just connected the 4 data lines directly to SPI and that was it (I use SD->MicroSD with some wires soldered directly on the pads). Which pins are you using?

[ladyada]

static const uint8_t MOSI = 18; static const uint8_t MISO = 19; static const uint8_t SCK = 5;

and cs on any pin really, but im using

define SD_CS 33

other than the SD card, all other SPI devices ive tested are working perfectly - TFT display, LoRa and RFM radio modules, VS1053

[me-no-dev]

Done :)

[ladyada]

looks good - would you like me to re-test?

[me-no-dev]

Sure :) Confirmation is always good, but I was able to reproduce the issue and after the fix, was not able to anymore, regardless of what I did :) I wonder how it was working while I was developing the library? BTW I tested with your pin configuration

void mountSdCard(){
    SPI.begin(5,19,18);
    if(!SD.begin(33)){
        Serial.println("Card Mount Failed");
        return;
    }
}

[ladyada]

hiya - ok so for one of my feather setups, with cardcs on IO 27, it now works every time. on another feather, with cs on IO 14 it still doesnt work :/

Initializing SD card...[E][sd_diskio.cpp:99] sdSelectCard(): timeout [W][sd_diskio.cpp:452] ff_sd_initialize(): GO_IDLE_STATE failed [E][sd_diskio.cpp:724] sdcard_mount(): f_mount failed 0x(3) failed!

[me-no-dev]

maybe on io14 there is another issue? I mean, if SPI is properly configured, and you use pins below 34, the lib itself does not care which pin you have selected. It calls digitalWrite to control SS

[ladyada]

yeah unknown. ill investigate more later... :)

[NickWaterton]

Interesting, I am having the same problem. Using the TFT feather wing (CS 14), the SD card works about 50% of the time, using the music maker featherwing, I can't get the same SD card to work at all (also CS 14).

SPI works fine with graphics and music etc, it's just the SD card that is unreliable. If I wasn't having a similar problem (but not as bad) with the TFT featherwing, I'd suspect a bad reader on the music maker.

When I have a chance I'll try it with an M0 or a WICED, see if they work with the music maker.

[badcf00d]

I'm using the same pins as ladyada, coming from the adalogger featherwing, and I can't get the card to mount at all using:

#include <SD.h>
#include <SPI.h>

void setup() {
  Serial.begin(115200);
  SPI.begin(5, 19, 18);
  if (!SD.begin(33)) {
    Serial.println("Card Mount Failed");
  }
}

SD card works in an M0 datalogger, but no luck with the ESP32 :/

[ladyada]

@me-no-dev hmm do you mind if we send you some hardware that you can test with? the SD card works if we use our ported 'arduino-SD-library' but not with the SD library ya'll included. so I think its some init thing?

[me-no-dev]

@ladyada yes please! let's get this fixed :) How are we going to arrange this?

[me-no-dev]

done :)

[ladyada]

k email addr deleted, we'll reply

[dstoiko]

[E][sd_diskio.cpp:724] sdcard_mount(): f_mount failed 0x(3) @me-no-dev thanks for this lib! Having the same issue here... Thought it was an issue with pull-up resistors at first but it doesn't seem to be. Any updates on this?

[me-no-dev]

Things just showed up :) will solder the boards tonight and prep everything

[dstoiko]

That sounds exciting

[ladyada]

yay - we have a full kit of cousre, and can try replicating any branches/fixes

[dstoiko]

So do we know where this issue comes from? What can I do to further test?

[me-no-dev]

OK I need more info on the failing cards because here is my first result at this (Feather selected as board) Maybe there are particular steps to follow?:

[ladyada]

can you try a few times? also try plugging the esp32 into the tft feather and drawing a BMP from SD? that's the only thing i can say we tried and had difficulty with :)

[NickWaterton]

I found with the tft feather, it works about 50% of the time.

I was using the music maker feather also, and it works 0% of the time with that (same pins).

I haven tried the data logger feather at all.

@NickWaterton Are you referring to the SD card slot on the music maker wing? The VS1053 part works fine using the ESP32-Radio project.

[me-no-dev]

Hit a wall with the TFT Wing :) looking into it :) @bbx10 yes, SD is the issue

[me-no-dev]

@ladyada I seem to get intermittent issues wit the touch on the TFT as well. Like it will not start every once in a while. Have you notice this?

[me-no-dev]

please try the latest commit :)

[me-no-dev]

And here is a JPEG read from the SD card :)

[bbx10]

@me-no-dev Works fine with SD card slot on Feather Adalogger (CS=33) and Music Maker (CS=14).

[dstoiko]

@me-no-dev @ladyada Our config is custom, nothing to do with Feather. We have an ESP32-DevKitC with a WROOM-32, mounted on our PCB, and we've tried several different µSD/SD modules, all with the same intermittent mounting error:

• Adafruit µSD module (https://www.adafruit.com/product/254)
• "normal" SD module with adapter for µSD
• Bare µSD module with 10k resistors as shown per this documentation Again no luck with any of those options. We have only this on the SPI bus. We have tried on our PCB and off of it on a breadboard with just the ESP32 and the SD module.

As a side note, when using an SPI-based LED matrix module (MAX7219) on the bus, trying to use the SD module crashes the ESP32. We had to remove the SD from our configuration which is pretty debilitating at the moment.

Any ideas where the solution might be?

@ladyada you said your port of the Adafruit SD library for Arduino boards worked 100%. I haven't seen that port anywhere, just the Arduino version. Do you have it on one of your repos?

[me-no-dev]

@dstoiko did you try the latest commit? It's not a fix just for this board.

[me-no-dev]

@dstoiko also I do not see you mention which pins you are using for SPI

[NickWaterton]

Yes, the VS1053 works just fine. The SD card slot does not. I didn’t build the ESP32-Radio project, I’m streaming Bluetooth audio and playing it via the music maker. I noticed that the SD card slot doesn’t work though, so I tried it on a tft feather I have, and it works about 50% of the time.

I’m not using the sd card slot in my project, but I tried to get it to work (for testing) and couldn’t.

[dstoiko]

@me-no-dev will try asap. We are using these pins: MOSI -> 23 MISO -> 19 SCK -> 18 CS -> 5

[me-no-dev]

@dstoiko pins look good! You and @NickWaterton should have success if using the latest code.

[ladyada]

hiya! @dstoiko yah the default SD library worked for us, see it in https://github.com/adafruit/arduino-esp32/tree/d602169ebcd126c309009e87c1e455f2c892d08f @me-no-dev not sure about the touch screen, it does share SPI pins and also the touch chip is annoying in that it changes modes based on SPI floating voltages on bootup. ill take a look again soon!

[me-no-dev]

@ladyada it's possible that it was caused by the sd card stuff ;) have not seen if happen since SD is working.

[ladyada]

awesome :) you also have some fun hardware to try other stuff!

[me-no-dev]

@ladyada yeah! thanks for that! So far I have tried all but the servo shield and is working as expected :)

In our WROVER_KIT fork of the ILI driver, I have implemented direct drawing of bmp and jpeg files and buffers. Maybe you will like to add this for the ESP32 platform to your ILI driver as well?

[ladyada]

oh yah that would be awesome. if you can submit a PR and just make sure it still compiles for arduino. jpg decoding would be great and would probably work on other M4/high speed platforms!

[me-no-dev]

There are two ways to do this. ESP32 has the decoder in ROM, but the code footprint is also small. So either compile it only for ESP32 and use the functions in ROM, or also include the source for other compatible platforms. And I agree ;) definitely not an AVR territory :)

[Edzelf]

SD is working now correctly.

[NickWaterton]

Just wanted to say the SD card is working correctly on the Musicmaker feather now also.

[dstoiko]

Working more reliably now, mounting consistently all the time. I still get an error when running the SDCard test code : [W][sd_diskio.cpp:137] sdCommand(): no token received... Any ideas?

Also, in this example the functions that open files dont close() them. Is that normal behavior? I thought you needed to close the file after writing to it at least.

Yes you need to close the file if you open it

[dstoiko]

@me-no-dev I was saying that because in the arduino-esp32 SD test example, file.close() is not used in the file manipulation functions readFile, writeFile and appendFile.

[me-no-dev]

@dstoiko must be error on my end :(

[dstoiko]

@me-no-dev made a tiny PR for that

[me-no-dev]

thank you @dstoiko merged :)

[capedra]

Wow, five months have been passed and the SD card problem persists now on MH-ET Live ESP32 Minikit.

[me-no-dev]

@capedra wow... that could be so many things... what is "MH-ET Live ESP32 Minikit" anyway? And how come I can mount all of my cards on all of my dev boards?
