各位好：
我司自己设计了AM335x 的一个 开发板， 现在遇到如下几个问题。
1： uboot 里面 可正常识别到emmc
- Device: OMAP SD/MMC
- Manufacturer ID: 3
- OEM: 5344
- Name: SC16G
- Tran Speed: 50000000
- Rd Block Len: 512
- SD version 3.0
- High Capacity: Yes
- Capacity: 14.8 GiB
- Bus Width: 4-bit
- U-Boot# mmc dev 1
- mmc1(part 0) is current device
- U-Boot# mmcinfo
- Device: OMAP SD/MMC
- Manufacturer ID: 11
- OEM: 100
- Name: 004G6
- Tran Speed: 52000000
- Rd Block Len: 512
- MMC version 4.0
- High Capacity: Yes
- Capacity: 3.7 GiB
- Bus Width: 4-bit
2： 正常启动的时候log
