@ESP_igrr wrote, SD SPI driver is almost ready! Hope to release it soon so i think this comes asap in the ESP-IDF.
Only to be sure: Should the SD card example already work in SPI-mode with current ESP-IDF?
I am asking because I have problems to get the example working. Since I have a breadboard setup I wanted to clarify if it is more a SW or a HW issue. ;)
Thank you very much in advance.

Hi @rudi, would you confirm if 10K pull up still required for SPI MOSI pin as per the link from @ESP_igrr. I am using the TTGO Micro ESP32 module and I want to connect the MicroSD card to enable firmware updates from it.

Thanks

Glenn
