WROVER Dev Kit 4.1 LCD and SD Not Working

[czuvich]

I am trying to get the WROVER Dev Kit LCD and SD to work together. I removed R167, and I can now show results in the LCD even if an SD Card is inserted; however, when I try to initialize the SD card it fails to mount (see error below). If I initialize ONLY the SD, then the SD works fine. Is there any way to use the SD Card and LCD?

I basically the LCD code on github (https://github.com/espressif/WROVER_KIT_LCD), and I added SPI and SD initialization after.

Error
19:49:03.595 -> [W][sd_diskio.cpp:471] ff_sd_initialize(): GO_IDLE_STATE failed
19:49:03.595 -> [E][sd_diskio.cpp:739] sdcard_mount(): f_mount failed 0x(3)

Code
// init code for LCD
SPI.begin(14, 2, 15, 13);
if (!SD.begin(13)) {
ESP_LOGE(LOG_TAG, "<< Failed. LocalStorage is not available.");
}

I have been trying for weeks to get just the SD card to work on my V4.1 DEV KIT. I haven't removed the resistor that prevents the LCD from working with the SD card inserted. I Don't care about that right now. I just want the SD card to work. The presence of the SD card seems to be detected because I get a different error when the card is missing.

I am trying to run the use the SDcardtest example and am using the Arduino IDE with the board selected as "ESP WROVER Module".

Here are my test results:

This is very frustrating..

I have the same problem. Did you find a solution for it?

Where did u see thatR167 should be removed?

[ESP_Roland]

I have the same board but I cannot reproduce the issue. Can you please try the following example if it is not the "SDcardtest" example you are mentioning?

https://github.com/espressif/esp-idf/tr ... ge/sd_card

What IDF version are you using?

[Segmentation Fault]

I am using Arduino IDE.

I could make a sample, would that be of help?

[ESP_Roland]

Thanks Segmentation Fault. Yes, any code could help reproduce the issue.

But firstly, if you just could try the given example with pure IDF then we could eliminate the possibility that the board with SD is not working and have the Arduino people look at it.

The SD card works fine with this code, the LCD outputs white color.
To make the LCD work must a) remove lines 59-109 along with b) removing the SD card.

Unfortunately, I am not that experienced with esp-idf yet, but I will try the "sd_card" example and give you an update on that as well

Thanks Segmentation Fault.

In the meantime, I moved the topic to the Arduino sub-forum because I think this will be an Arduino issue.

Hello ESP_Roland,

I read your topic concerning the SD and display issue on a Wrover board.
I also have this kind of problems using a ESP-wroom-32 board from doit dev.kit v1.

Same conditions arduino ide when testing the SD apart its ok. testing the TFT apart also ok.
Using both in one script display will stay blank and the SD gives no responce.

Will you be please so kind to send the arduino forum link?

Many thanks in advance.
