Hi
I am designing a custom motherboard for my project, but using the TE0701 as a guide for the few I/O that I need
I see on the TE0701 the WP and CD signals form the SD Card socket are routed to the CPLD. I do not see that they are connected through to the TE720
On the reference TE720 Vivado project I see these signals are routed to EMIO but not actually connected.
Do I have to make any provision for WP and CD signals in order to a) boot from SD Card, and b) Access SD from petalinux?
Thanks

Hi,
on TE0701 SD-WP and SD-CD goes to Baseboard CPLD. Functionality is CPLD-Version dependents.
Card detect is used to switch Boot Mode of the Module FPGA. On the newest CPLD Firmware both Pins are also available from PL via CPLD RGPIO Interface.
