Hi
I am using SMARC card based on iMX6 solo platform.
The pin outs from the SMARC based card has CD and WP(as GPIO pins from iMX6) along with CLK ,CMD and 4 Data lines.
So what will be the state of CD and WP if i am not using these line for my application.
If i am using SDIO as an I/O device is there any recommendation for data lines , cmd lines and clk .
because as per SDIO spec Data3 line need pull up.
I have attached the pins from SMARC card for your reference.
Kindly please confirm.
Regards
Ashutosh
Q. So what will be the state of CD and WP if i am not using these line for my application.
A. Both these pins should be tied to GND on the i.MX6 side.
Q. If i am using SDIO as an I/O device is there any recommendation for data lines , cmd lines and clk .
A. No external pull-ups/pull-downs are required on the data/cmd/clk lines for normal SDIO operation.
Have a great day,
Artur
