Extend SD card select timeout

Board

DOIT ESP32 DEVKIT V1

Device Description

I'm using a common Arduino SD Card PCB that is connected with 14cm wires to the ESP32

Hardware Configuration

I'm using the VSPI Pins 18, 19, 23 and 5

Version

other

IDE Name

Arduino IDE

Operating System

Arch Linux

Flash frequency

80 MHz

PSRAM enabled

no

Upload speed

921600

Description

Updating to arduino-esp32 v2.0.2 caused the SD-Card to not work anymore (previously I used 1.0.6). The solutions in the other issues didn't work.

Reverting all changes in the file sd_diskio.cpp gave me the same functionality as in 1.0.6.

Looking at the code I suspected the sdWait timeout in the sdSelectCard function, because in 1.0.6 a timeout was just ignored but this is now fixed. In other places (sdWriteBytes) a timeout of 500ms is used so I changed the value to that and now my card is recognized.

For me just chaning the timeout in v2.0.2 fixed the issue.

Debug Message

Before changing the timeout:

[   313][W][sd_diskio.cpp:104] sdWait(): Wait Failed
[   313][E][sd_diskio.cpp:126] sdSelectCard(): Select Failed
[   313][W][sd_diskio.cpp:510] ff_sd_initialize(): GO_IDLE_STATE failed
[   318][E][sd_diskio.cpp:795] sdcard_mount(): f_mount failed: (3) The physical drive cannot work
[   627][W][sd_diskio.cpp:104] sdWait(): Wait Failed
[   627][E][sd_diskio.cpp:126] sdSelectCard(): Select Failed
Card Mount Failed

After changing the timeout:

[    14][W][sd_diskio.cpp:186] sdCommand(): token error [59] 0x5
SD Card Type: SDSC
SD Card Size: 1947MB

@NomAnor Hi, changing timeout to 500ms solves the mounting issue for you? :) Thanks

Sadly not. At first it worked but after a re-upload I had the same problem again. In the end I reverted all changes to sd_diskio.cpp back to 1.0.6. I still got the "Select failed" message but because the return was missing in

arduino-esp32/libraries/SD/src/sd_diskio.cpp

Lines 125 to 129 in caef400

	if (!s) {
	log_e("Select Failed");
	digitalWrite(card->ssPin, HIGH);
	return false;
	}

that was ignored. The missing return is clearly a bug but ignoring the failure kept the code going and I could read files. My SD-Card was rather old maybe it has to do with that.
