清理跟rebulid是不一样的

本来nandflash的系统一直到emmc后，本来SD卡用通道0是ok的，现在...

[SDMMCCh2] SDHCControllerIst - Card is Inserted!

[SDMMCCh2] Setting for 1 bit mode , Clock Rate = 100000 Hz

[SDMMCCh2] HandleErrors - ERR CMD:5 : If the card is not a SDIO, CMD 5 does not work in reason.

[SDMMCCh2] HandleErrors - ERR CMD:1 : If the card is not a MMC, CMD 1 does not work in reason.

[SDBUS] SD/SDHC supports the high-speed mode.

[SDMMCCh2] Setting for 4 bit mode , Clock Rate = 50000000 Hz

[SDMMCCh2] HandleErrors - ERR CMD:17 : [SDMMCCh2] HandleErrors - DAT END BIT Error...

[SDMMCCh2] HandleErrors - ERR CMD:17 : [SDMMCCh2] HandleErrors - DAT END BIT Error...

[SDMMCCh2] HandleErrors - ERR CMD:17 : [SDMMCCh2] HandleErrors - DAT END BIT Error...

然后快要放弃的时候提交之前，清理，bulid，然后解决了...靠
