Doit ESP32 DevKit v1 and SD Card Reader

[photon]

Hello,
I am trying to connect a doit ESP32 DevKit v1 to an SD Card Reader. I am currently trying this one: https://m.banggood.com/3_3V5V-Micro-SD- ... 64192.html. What I did is I connected the module according to mapping in the ESP32 sd card example and used the example code. When I boot the ESP32 I get following error:

Code: Select all

rst:0x10 (RTCWDT_RTC_RESET),boot:0x37 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
Falling back to built-in command interpreter.
OK

The question is if this module can be used with my ESP32, and if no, which module should I used instead. Or, if I am doing something wrong instead.
Thanks a lot!

Did you read the notes about GPIO12? Smells like that GPIO has the wrong signal level on bootup.

Hi,
on a second attempt I disconnected GPIO12 during startup and connected it back just before the sample routine is executed. Now my ESP32 starts, but it gives me another error:

Code: Select all

␛[0;32mI (23324) example: Initializing SD card␛[0m

␛[0;31mE (23344) example: Failed to initialize the card (265). Make sure SD card lines have pull-up resistors in place.␛[0m

I was under impression that the SD Reader I use has pull-up resistors in place already...?

[photon]

Out of curiosity I also tried the SDMMC_HOST_FLAG_1BIT and it did not work either. I suspect there is some problem with the reader itself, I'll try the arduino one instead and will post here if I had more luck there, even though this reader works in SPI mode only. Thank you for your answer!

[photon]

Now I am lost completely. I measured the current levels on the sd card reader, the resistivity of resistors on the board, I even tried my own 10k resistors as pull-ups but nothing helped Where should I start looking, before the other reader arrives? I tried 3 different sd-cards also. Should I try to solder wires onto the sd directly and use 10k pull-ups for CMD, CLK and D0?

For the case when you choose SDMMC_HOST_FLAG_1BIT, please try setting log level to "Verbose" in menuconfig -> component config -> log output, and then attach the log here.

[photon]

Thank you for the response. I used
host.flags = SDMMC_HOST_FLAG_1BIT;
Output is following:

This was for 2GB microSD. After that I removed the card completely, and got the same output Therefore, out of curiosity, I tried a different card (Samsung EVO Plus Micro SDXC USH-1 U3 128GB Class10 ), and got completely different output:

Do you have any idea what could be the cause? I do not know if this is a HW issue, or something I should change in the program...?

Tried more ordinary Samsung 32GB MicroSDHC and got exactly the same output as for 128GB. This most likely a problem with either the reader or wiring, otherwise I cannot explain it.
