Upgrading to 2.0 breaks SD function

[rayb12]

I just upgraded from 1.06 to 2.0 of the ESP32 Arduino core. Using 1.06 all Sd functions were working properly. After upgrading to 2.0 SD fails to begin. This is a custom board and SD is connected as per the standard SD connections (as in the picture in the Sd library folder).

I copied the Sd example from the Sd library here and it does the same thing, fails to mount SD card.
As a test, I switched back to ver# 1.06 and all SD functions work properly again. Am I missing something?

I searched this forum but could not find anything specifically related to my problem. I'm using the SD library, not the SDMMC library.

System: Arduino IDE
Board Selected in Arduino IDE: ESP32 Dev Module

Code:
if(!SD.begin(){
Serial.println("Card Mount Failed");
return;
}
Code above always returns failed.
I also tried the following code:
if(!SD.begin(5){
Serial.println("Card Mount Failed");
return;
}
I also changed SD cards just in case, but still same problem.

Hope this is enough info. Any help is greatly appreciated!!!

Sorry, but this may be not enough info. There is many people using SD library in 2.0.0, including myself, and we have no problem with it, but I have to admit that recently i am using mostly esp32S2 and SD card with custom SPIClass object.
Maybe if you enable verbose logging level, then you will have more info for us?

Thank you chegewara!
Here is the verbose output (I apologize if this is not what you were asking for):

Thank you for any help in advance!

[chegewara]

It looks like hardware problem, but who knows.
Could you try to use SPIClass to initialize SD card?

[rayb12]

@chegewara,
I added code to use SPIClass as per your suggestion.

I downgraded back to ver# 1.06 and turned on verbose logging to see why my SD is failing on ver# 2.0. I discovered that it does indeed fail on sdWait() and sdSelectCard(). However, it then mounts correctly and the SD seems to function correctly (read/write, etc.).

I forgot to mention above, I'm using an ESP32 WROOM module in a custom board and using a micro SD instead of a mini SD. I checked all the wiring and the SD is indeed connected properly.

Here is my code partially taken from the SD example:

#define SDM_CLK 18
#define SDM_MISO 19
#define SDM_MOSI 23
#define SDM_CS 5

void setup(){
Serial.begin(115200);
SPIClass sdSPI(HSPI);
sdSPI.begin(SDM_CLK,SDM_MISO,SDM_MOSI,SDM_CS);

  if(SD.begin(SDM_CS, sdSPI)){ //, *hspi)){
      Serial.println("Card Mount Success");
  }
  else{
    Serial.println("SD failed");
  }
  uint8_t cardType = SD.cardType();
  if(cardType == CARD_NONE){
      Serial.println("No SD card attached");
      return;
  }
  Serial.print("SD Card Type: ");
  if(cardType == CARD_MMC){
      Serial.println("MMC");
  } else if(cardType == CARD_SD){
      Serial.println("SDSC");
  } else if(cardType == CARD_SDHC){
      Serial.println("SDHC");
  } else {
      Serial.println("UNKNOWN");
  }
  uint64_t cardSize = SD.cardSize() / (1024 * 1024);
  Serial.printf("SD Card Size: %lluMB\n", cardSize);
  Serial.printf("Total space: %lluMB\n", SD.totalBytes() / (1024 * 1024));
  Serial.printf("Used space: %lluMB\n", SD.usedBytes() / (1024 * 1024));

}

And here is the serial logs from the above code using ver# 1.06:

Not sure what the garbage is right after "entry" above, but, as you can see, everything fails using ver# 2.0. I also tried not using the SPI class to initialize the SD card and I get the same results.

Any help is greatly appreciated!

[chegewara]

I can confirm. Stock SD card example is giving this result.
I tested with idf-master branch and i have the same result.

Bump

@me-no-dev

Any ideas on this issue?

[me-no-dev]

@P-R-O-C-H-Y please have a look

@me-no-dev
For me the SD card is working fine on version 2.0.
Tested with master branch both SD examples, no errors or warnings.

System: Arduino IDE / VS code
Board: ESP32 Wrover kit v4.1

I dont have more ESP boards home, can try on more boards tomorrow.

[rayb12]

@P-R-O-C-H-Y
Did you get a chance to try on more ESP boards yet? We are really stuck over here. We have tried several different micro SD cards. Formatted with SD-Formatter as per other suggestions. I'm wondering if it could be a timing issue? In reading other posts, some have mentioned issues with needing to slow the SPI bus down to around 10MHZ. Can you tell me how to do that with ver# 2.0? I'm just grasping at anything at the moment.

Any help is greatly appreciated!

[P-R-O-C-H-Y]

@rayb12
Now builded on esp32s2 with same result. Everything is working. IDK where is the problem.
SPI speed is 80MHz and working perfectly. Will do more tests.

CODE:

#define SD_CS 34
#define SD_SCK 36
#define SD_MISO 37
#define SD_MOSI 35

SPIClass sd_spi;

void setup() 
{
  Serial.begin(115200);
  while (!Serial) {}

  sd_spi.begin(SD_SCK,SD_MISO,SD_MOSI,SD_CS); // The bultin SD card SPI for WROVER
 
  if (!SD.begin(SD_CS,sd_spi)) 
  {
        Serial.println("initialization failed!");
        while(1);
  }
  else
  {
        Serial.println("initialization done.");
  }

  listDir(SD,"/",0);
}

@rayb12
EDIT: got same issue like you get, when building in Arduino IDE, when in VS code its working.
Gonna find the problem.

[rayb12]

@P-R-O-C-H-Y
Thanks for looking into it. Look forward to you finding the problem. As side note, can you tell me where to change the SPI speed?
Thanks!

[P-R-O-C-H-Y]

@rayb12
Can you print your idf version?

Insert this code:

Serial.println("ESP-IDF version is: " + String(esp_get_idf_version()));

For changing the frequency of SPI, there is function:

SPI.setFrequency(uint32_t freq);

[P-R-O-C-H-Y]

@rayb12
Updated Arduino IDE with latest version of arduino-esp32 master branch and everything working correctly on ESP32 and ESP32S2. Can you try that?
