How to set pins to SD card low or to input?

Post by Arek » Mon 2018-11-26 13:47

Hi,

how can I set the VS1010 sd card connections to low (or preferably to inputs / tristate) via the serial GPIO.
If this is not possible then how can i do it programmed from SPI memory?

The reason is the use of the S8 SD card controller, which requires programming. The programming uses the SD connections, in my case "disturbed" by the VS1010 (serial resistor 470R does not help).

Thanks for any hints
