各位好
我司仿照mx6q_sabreasd做的开发板，参考飞凌的mx6x_v1.3开发板
软件版本比较老，uboot-2009-08，内核3.0.35
使用freescale的LTIB工具制作了mfg的引导文件，可以正常烧录
烧录后启动发现一个奇怪的现象，UBOOT阶段的打印丢失，打印从hw-breakpoint这一段开始。最后EMMC的错误请先忽略。
我开始以为是uboot阶段的串口设置有问题，检查了uboot的mx6q_sabresd的相关设置，没有发现异常。
比较悲催的是，如果使用同样的uboot和内核文件去给飞凌开发板烧写，是uboot阶段的打印有，而从hw-breakpoint这一段开始就没有打印了。已经调试了好几天，一直没有头绪。还请帮忙给个排查意见和指导方向。
下面是自制单板的内核打印，直接从hw开始。
hw-breakpoint: found 6 breakpoint and 1 watchpoint registers.
hw-breakpoint: 1 breakpoint(s) reserved for watchpoint single-step.
hw-breakpoint: maximum watchpoint size is 4 bytes.
