Hi

The ESP-WROVER-KIT_V4_1 does not use the 10k pull-up connected to SDCARD's DATA2 pin as recommended. So, I am assuming that internal pull up is enable. Am I correct?

I addition to that, I would to know if GPIO4 (D1), GPIO12(D2) and GPIO13(D3) can be used as regular GPIO pins in 1-line SD mode ...

Hi

I want to use a SDCARD in MMC mode with Arduino framework (SD_MMC library) with only for 1 bit data width.

The sdcard conexion is according https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card

My question:

Can I use GPIO4 (D1), GPIO12(D2) and GPIO13(D3) as regular IO pins ...
