客户说红灯亮不开机，送到店里我第一次开机正常没有问题，断电后重启亮红灯 二次不开机。第二天一试又是同样的现象，测主板供电1.5V 1.2V 3.3V都正常。查看打印信息显示如下  哪位师傅懂的请指教一下，谢谢 UART_115200 AC_ON AutoDQS0-[456789ABCD][3456789ABC][3456789ABCD][456789ABCDE]-[0x9878] AutoDQS1-[3456789ABCDE][3456789ABCDE][23456789ABCD][3456789ABCDE]-[0x8788] BIST0-OK BIST1-OK _U Relocation Offset is: 03b00000 [AT][MB][start ub][300] U-Boot 2011.06-00000-g9d9ca6b-dirty (Jan 27 2015 - 17:41:36) [NOS] UtopiaInit 1st UTOPIARegisterToUtopia is done[MBoot] Driver Register to Utopia uboot held at [3e0ddf60~3f400000],size=013220a0 CPU  : Madison Board: BD_MST066B_10AVX_14091_MADISON DRAM:  500 MiB Now running in RAM - U-Boot at: 3e500000 EMMC: DDR 48MHz eMMC 3.68 GB [75FFF8h] In:    serial Out:   serial Err:   serial Net:   No ethernet found.
