esp-idf: [TW#14134] SD Card example: A fatal error occurred: Timed out waiting for packet header (IDFGH-830)

I tried the SD Card example and get the following error messages:

First of all: Thanks for taking the time and helping me @llewellynnu !

I bought the esp32 from doit.am and there is no IO0. I’m still looking with the pinout mapping from the boot button where the IO could be, but still no success. When also EN is pulled down for programming, can i connect EN to IO2? And do i understand it right: I can just put a jumper or a wire from EN/IO0 to IO2, but IO2 is still connected to my sd card (at D1 with 10k pull up)? Or do i have to take off the wiring from IO2 to D1 and only after programming the esp32, i wire IO2 with D1 again?

In other news: I tried disconnecting IO12 and the error message changed:

E (1209) sdmmc_cmd: sdmmc_card_init: send_if_cond (1) returned 0x109
E (1209) example: Failed to initialize the card (265). Make sure SD card lines have pull-up resistors in place.
