If the pin is High, the SD memory card BootROM process will fail because the BootROM will assume there is no SD card available. The design intent is for the BootROM to access the SD card without testing the card detect status.
| Impact: | Minor. |
| Work-around: | Set MIO pin 0 Low during the SDIO boot sequence. |
| Configurations Affected: | Systems that use the SDIO boot mode. |
| Device Revision(s) Affected: | Refer to (Xilinx Answer 47916) - Zynq-7000 AP SoC Silicon Revision Differences |
