No response from MMC (CONFIG_MMC_TRACE)

[AlanWen]

I want to enable CMD response from the MMC with "#define CONFIG_MMC_TRACE" in mmc.h but there is nothing happened after I boot up the device.

======================================== mmc.h

struct bd_info;

#if CONFIG_IS_ENABLED(MMC_HS200_SUPPORT)

#define MMC_SUPPORTS_TUNING

#endif

#if CONFIG_IS_ENABLED(MMC_UHS_SUPPORT)

#define MMC_SUPPORTS_TUNING

#endif

#define CONFIG_MMC_TRACE

/* SD/MMC version bits; 8 flags, 8 major, 8 minor, 8 change */

#define SD_VERSION_SD (1U << 31)

#define MMC_VERSION_MMC (1U << 30)

...

Is there any issue with my operation ?

or

Is there any other way to show the CMD response ?

Thanks

[Rita_Wang]

Before you enable the #define CONFIG_MMC_TRACE" can system boot up well ?

[AlanWen]

Probably yes, I can boot up when first power on but I got failed while calling reboot command and encountered the "Error reading cluster" issue in u-boot. About the MMC response, I think it will show up any first time when I boot up the device but it did not show even the first boot up.
