2.2.1
To set the EVK board switches for normal operations, use these steps:
1. Attach the 5.0V DC Power Supply to Jack J6 and plug the AC end into an electrical
2. Slide USB 5V Switch (S14) to the ON position (up).
3. Slide Debug Switch (S22) to the OFF position (down).
4. Slide the Hold Switch (S1) to the OFF position (up).
5. Set the Boot Mode Selector Switch (S36) to the desired mode per Table 2.2.

Connector
i.MX23 EVK Hardware User’s Guide, Rev 1.1
Standard SD/MMC card connector connects to the i.MX23 device
via the SSP1 module. This module also shares with Ethernet
operations and an optional SPI Flash. 3.3V power is only supplied to
the connector when an SD/MMC Card is physically inserted into the
slot and the i.MX23 recognizes the presence of the card and turns
on power to the card. When SD/MMC power is turned on, Ethernet
operations are disconnected through a buffer chip.
