请问在DM385开发板中,为什么uboot的第二阶段不能运行?



开发环境:DM385, IPNC3.5

DM385的uboot启动的时候,MLO正常的加载启动后,可以读到u-boot.bin,为什么u-boot没有运行呢 ???

U-Boot 2010.06-dirty (Aug 09 2015 - 11:22:11) DM385_IPNC_3.50.00

DM385-GP rev 1.1

ARM clk: 600MHz DDR clk: 533MHz L3 clk: 200MHz IVA clk: 450MHz ISS clk: 400MHz DSP Default OFF DSS Default OFF

DRAM:  1 GiB MMC:   OMAP SD/MMC: 0, ON-BOARD SDIO: 1 Using default environment

The 2nd stage U-Boot will now be auto-loaded Please do not interrupt the countdown till DM385_IPNC prompt if 2nd stage is already flashed Hit any key to stop autoboot:  0 reading u-boot.bin

请大家帮忙分析一下,谢谢;
