ESP32 Wroom + SDcard plugin error

[SuksesAmin]

You have developed grblhal for people and you help us voluntarily, you are Hero!!.

I have a problem when using the sdcrad plugin. The error shown in the console is as below [MSG:Warning: Failed to initialize SD card] Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled. Core 1 register dump: PC : 0x400e7af0 PS : 0x00060530 A0 : 0x800e4c64 A1 : 0x3ffb64b0 A2 : 0x00000000 A3 : 0x3f404c8a A4 : 0x00000000 A5 : 0x0000001f A6 : 0x00001004 A7 : 0x3ffaed3c A8 : 0x00000000 A9 : 0x00000000 A10 : 0x00000000 A11 : 0x3ffb1ca0 A12 : 0x3ffb1c54 A13 : 0x00000000 A14 : 0x3ffb1ca0 A15 : 0x3ffb1c54 SAR : 0x00000020 EXCCAUSE: 0x0000001c EXCVADDR: 0x00000000 LBEG : 0x4000c46c LEND : 0x4000c477 LCOUNT : 0xffffffff Backtrace:0x400e7aed:0x3ffb64b0 0x400e4c61:0x3ffb64d0 0x400e605c:0x3ffb6510 0x400e327c:0x3ffb6550 0x400e4293:0x3ffb65d0 0x400e42dc:0x3ffb65f0 0x400e1d71:0x3ffb6610 0x400db6f1:0x3ffb6660 0x400d5b7c:0x3ffb66a0 0x400d5883:0x3ffb66c0 ELF file SHA256: a20ced2169f81b78 CPU halted.

Change this line https://github.com/grblHAL/ESP32/blob/6d08a106ff2ad1ab7911b6fec7f91c2c1b20a550/main/driver.c#L1816 to if(card && fs) {

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.

[SuksesAmin]

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); } } else { Serial.print(" FILE: "); Serial.print(file.name()); Serial.print(" SIZE: "); Serial.println(file.size()); } file = root.openNextFile(); } } void setup(){ Serial.begin(115200); SD.begin(SD_CS); if (!SD.begin(SD_CS)) { Serial.println("failed"); return; } uint8_t cardType = SD.cardType(); if (cardType == CARD_NONE) { Serial.println("No sdcard"); return; } Serial.println("Reading SD..."); listDir(SD, "/", 0); } void loop(){ }

[terjeio]

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?

[SuksesAmin]

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

[SuksesAmin]

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

[terjeio]

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

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

[SuksesAmin]

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

[terjeio]

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

[SuksesAmin]

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.

[SuksesAmin]

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.

[terjeio]

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.

[SuksesAmin]

this sdcard module that I use.

where can i get the schematic for v4.1?

[terjeio]

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.

[terjeio]

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?

[SuksesAmin]

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.

[terjeio]

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

[terjeio]

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