9. If you compile the kernel yourself, make the following code changes
kernel/arch/mips/xburst/soc-t31/chip-t31/isvp/Swan/board.hdetects the MMC GPIO
After the change:
/* ****************************GPIO MMC START******************************** */
#define GPIO_MMC_RST_N -1
#define GPIO_MMC_RST_N_LEVEL LOW_ENABLE
#define GPIO_MMC_CD_N GPIO_PB(18)
//#define GPIO_MMC_CD_N GPIO_PB(27)
#define GPIO_MMC_CD_N_LEVEL LOW_ENABLE
#define GPIO_MMC_PWR -1
#define GPIO_MMC_PWR_LEVEL HIGH_ENABLE
#define GPIO_MMC_WP_N -1
#define GPIO_MMC_WP_N_LEVEL LOW_ENABLE
/* ****************************GPIO MMC END******************************** */
The compiled kernel recognizes MMC cards.
10. If you build U-Boot yourself and the chip is a T31ZX, a patch must be applied
