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

How can one JTAG debug when SDCard is attached to the same pins as it is in Espressif WROVER and Olimex EVB designs??
