Hi, all

 

SD/MMC manufacture mode is required to be implemented in my customized board which is based on iMX6UL. With RM, the signal SD1_CD_B can come from pad CSI_DATA05 (ALT8) or GPIO1_IO03 (ALT4) or UART1_RTS_B (ALT2). Please let me know which pin should be used as SD1_CD_B so that BOOT ROM can recognize the SD card on uSDHC1 interface. Thanks!
