About CD pin of MCIMX6DL-SDP at SD Bootting

Is CD signal used when it boots from SD2 port?


According to the reference manual and Datasheet, for USDHC-2 boot, GPIO_4 (R6 pin) is used as a CD signal.


ReferenceManual: (IMX6DLRM.pdf Rev1)
- Table 8-18. SD/MMC IOMUX Pin Configuration(P.425)
- Table 67-2. USDHC2 External Signals(P.5540)


DataSheet: (IMX6DLIEC.pdf Rev2.1)
- Table 89. Interface Allocation During Boot(P.133)


However, in MCIMX6DL-SDP, GPIO2_2 (F16 pin) is used.

These have inconsistency.


Should GPIO2_2 (F16 pin) be used in order to boot from SD2 port?
