Could anyone explain to me the mechanism that the Hardware devices select the right SD port to communicate.
The Atheros wifi module is now connected to the SD2 port of the iMX53 AP. There will be configuration somewhere, to tell the wifi module that it is communicating with the SD2 port, not the SD1,3,4 ports.
Where is this configuration?
And if I have another wifi module, and want to connect this module to the SD1 port of the iMX53, how can I do this?
