Hello,

 

i would like activate D[0-4] on sd port, i don't find, how to activate D1,D2,D3 ?

 

In datasheet volume 1:

Table 10-3. SD Signals:

SD Card Data bits 0 to 3

Bidirectional port used to transfer data to and from SD/MMC card.

By default, after power up or reset, only D[0] is used for data transfer. A wider data

bus can be configured for data transfer, using D[3:0].

Note: Unused data lines will be tri-stated by the SoC logic.
