ESP32 Wroom + SDcard plugin error about esp32 HOT 17 CLOSED

Change this line

and the guru should keep meditating.

If you get the Failed to initialize SD card message when a formatted card is inserted then check your wiring as well.

from esp32.

yes. now
[MSG:Warning: Failed to initialize SD card]
error:60 - SD Card mount failed.

I have tested, the wiring work well using this sketch

#include "FS.h"
#include "SD.h"
#define SD_CS 5
void listDir(fs::FS &fs, const char * dirname, uint8_t levels){
Serial.printf("Listing directory: %s\n", dirname);
File root = fs.open(dirname);
if(!root){
Serial.println("Failed to open directory");
return;
}
if(!root.isDirectory()){
Serial.println("Not a directory");
return;
}
File file = root.openNextFile();
while(file){
if(file.isDirectory()){
Serial.print(" DIR : ");
Serial.println(file.name());
if(levels){
listDir(fs, file.name(), levels -1);

Serial.print(" FILE: ");
Serial.print(file.name());

Your test program is using the same pins for communicating with the card as grblHAL does?
Which board map are you using - there could be pin conflicts?

from esp32.

Yes, it is using the same pins. 8GB microsd and bdring v4

from esp32.

I left all settings as default except CMakeLists.txt. I changed it on line 33 from OFF to ON

from esp32.

Which version of the SDK are you using? You can use $I to check:

...
[DRIVER OPTIONS:v4.3.1-dirty]
...

from esp32.

[FIRMWARE:grblHAL]
[NVS STORAGE:*FLASH]
[DRIVER:ESP32]
[DRIVER VERSION:220726]
[DRIVER OPTIONS:v4.3.2-dirty]
[BOARD:BDRING v4]

from esp32.

I have now tested with the same board map as you and it works for me. A bug/regression/breaking change in the IDF framework?
Anyway here is the binary that works for me:
app-template.zip

from esp32.

I have tried compiling the sd_card example program from esp-idf which also doesn't work. I'm confused, it's working on arduino ide with a libraries that also made by Espressif.

Using library FS at version 2.0.0 in folder: C:\Users\DASHA\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.3\libraries\FS

Using library SD at version 2.0.0 in folder: C:\Users\DASHA\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.3\libraries\SD

Using library SPI at version 2.0.0 in folder: C:\Users\DASHA\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.3\libraries\SPI

So, the problem is coming from my hardware or isp idf on my computer. I will try other hardware after buying it.

from esp32.

Now it works with grblhal after I removed the LVC125A IC and connected it directly to the eps32 pin. Still working with the Arduino IDE sketch above.

Hope this helps all of you who are having the same problem.

from esp32.

after I removed the LVC125A IC

On which hardware? The schematic I have for for the V4.1 board do not show any pin buffering.

from esp32.

this sdcard module that I use.

where can i get the schematic for v4.1?

from esp32.

this sdcard module that I use.

ok, so the buffer is on module - I have not seen that before. It needs 5V VCC? This since there is a regulator on the module, did you supply that?

where can i get the schematic for v4.1?

I believe I found it here.

from esp32.

Hmm - maybe this module is not suited for the ESP32 as, IIRC, it is not 5V tolerant. If supplied with 5V it will fry the ESP32 inputs?

from esp32.

Yes, I'm supplying this with 5v connected to v-in pin of esp32. The AMS117 is 3.3V. so i think it's safe.

I also use this module for stm32f103. the miso, mosi, clk and cs pins are connected to the controller via the LVC12SA ic.

from esp32.

Most STM32F103 pins are 5v tolerant, not sure about the ESP32 - the MISO pin is an input to the MCU.

from esp32.

Closing as I've had hours upon hours of successful SD card streaming with the ESP32 recently.
