I am continuing trying this. With two new microsd cards : - A Sandisk 2go (from a blackberry smartphone), freshly formatted Fat32, I get the same error message than previously with the cmd=51 error code : E (69025) sdspi_host: sdspi_host_start_command: cmd=51 error=0x108 E (69026) sdmmc_cmd: sdmmc_c...

I have edited my prevoius post to correct the os.mountsd(True) so other following the post will get correct info. Thanks for the explanation, I was thinking that I had read it without being woken up as I didn't understand where I had copied this line from :) I did just make a 2 minute video of me d...

With all these posts it seems that reading a microsd card on an ESP32 in python should be doable :) I don't have a microsd-SD card adapter and I'd like to be able to use my microsdcard board so I have tried again now that I (think I) fully understand the pullup thing and that I know that the microsd...

Thanks for this information, I will have a try at the 1-line mode tonight. Within this mode, is there any need to add external pull-ups or are they "software-handled"? Some updates on this. I am still unable to access the sd card so I will give more explanation about what I have done so far, hoping...

Do you have all the needed pull-up resistors mentioned in the Wiki ? reading in the documentation that "In most cases, external pullup can be omitted and an internal pullup can be enabled using a gpio_pullup_en(GPIO_NUM_12); call. This is handled by SDCard driver." I was thinking that I had not to ...

Just tried to see if I got more luck using Loboris port and for the time being I am stucked. If someone reading this thread managed to use the SPI mode for a sdcard adapter, don't hesitate to commend on the edicated thread

Hello, based on what I have learnt in this thread I am now trying to get my MicroSD Card Adapter to work with my ESP32 Board. The hardware I got is : Catalex MicroSD Card adapter (the one described here ) A devkit ESP32 board (looking like the one shown there ) I have followed the instructions and t...

There is a number of different ports for MicroPython on ESP32. I am using the unofficial one known as the the Laboris port. I have not had a problem with using the SD card with it in both 4 line mode and 1 line mode and do believe SPI mode has now been added to the port as well. see laboris port wi...

Just like you, I am quite new to micropython on esp32 and the first step for my project was/is to be able to read the content of a SD card and I am stucked there. I am still trying different pins configurations but for the time being, I always get the no sd card message. Will update this thread if/w...

[quote=OutoftheBOTS_ post_id=24400 time=1515211808 user_id=3423] You could easily use something like this as an external MP3 device that is easily controlled my a MicroPython board https://www.ebay.com/itm/U-disk-audio-play-Mini-TF-SD-Card-MP3-Sound-Module-For-PIC-Arduino-WTV020-SD-16P/222040267674?...
