Some help with the settings of the SDIO Pins.

0693W00000JMQ1uQAH.jpgHow I understand from this schematics: PC8 and PD2 have pull-up resistors connected to them while the rest of them don't, this means that the rest should get Pull-up resistor in the settings of the GPIO and this will enable the pull-up resistor from the MCU. The instruction that I use is from this video https://www.youtube.com/watch?v=I9KDN1o6924&t=608s.

Also I found the schematics for the board in the video, and there all lines have pull-up resistors connected to them while in my schematics only 2 lines have pull-up resistors.

Based on this schematics and on the resistance connected to the lines:

1. What clock frequencies would be best suited for SDIO in the Clock section of the CubeMX? I use the 48MHz, is that to high?

2. What would be the settings for the PINS in the GPIO settings of the SDIO?
