使用beaglebone black提供的pcb制作的板子。
不同的地方为：BBB原来的cpu为AM3358（主频1000MHZ），我使用了AM3359（主频800MHZ）。
其他器件什么的都相同。
内核，uboot和根文件系统都是使用的ti官方提供的ti-sdk-am335x-evm-07.00.00.00中的。
不同的地方：删除了uboot中read_eeprom部分代码；内核有添加几个驱动。
3.问题现象
(1)自己制作的板子使用过程中出现偶尔死机的现象，所有log几乎相同，都是“Unable to handle kernel paging request at virtual address xxxxx”，如下：
[& & 5.675222] Unable to handle kernel paging request at virtual address f9f659a4& && && && && && && && &&&

[& & 5.764390] Process mount.sh (pid: 977, stack limit = 0xdb930240)& && && && &
(2)使用同一套软件（uboot，内核，根文件系统等等）的购买的BBB板子就没有出现死机的情况。
4.采取的措施
(1)咨询了TI技术支持，用AM3359替换AM3358后，在uboot中把MPU_DPLL改为800MHZ即可（其实内核会自动更改的）。此办法无用。
(2)参照ti提供的am335x ddr3 software leveling调校ddr3的配置，也没有效果。
不知道各位大神有没有什么想法和建议，应该从哪一方面分析解决这个问题?

哦，我怀疑，你们之前是不是没有焊好，然后换了个片子就焊好了......

不是这个问题，都是让工厂焊的。用3359的焊了4块，死机现象是一致的；后来用3358焊的4块，都很正常。
