omapl138核心板系统热启动后ubifs报段地址访问异常错误

custar

我们在使用的核心板是OMAPL138 128M内存规格，但是在开发板快速体验手册中提供的U-BOOT参数配置命令是：从SD卡启动：
; S8 g% F% x0 s5 F* \# N- \在3秒内按任意键进入u-boot命令行，执行以下命令设置为SD卡启动：
" E; F3 P8 F$ ~8 vU-Boot > setenv bootcmd 'mmcinfo;mmc init;fatload mmc 0 c0700000 uImage;bootm'
8 J# W9 X& K( E U-Boot > setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=128M

, k  i5 g# W9 Y" C& g从FLASH启动：
在U-Boot命令行执行以下命令来设置为NAND FLASH启动系统。
U-Boot > setenv bootcmd 'nboot.e 0xc0700000 0 0x120000; bootm'
U-Boot > setenv bootargs 'console=ttyS2,115200n8 ip=off ubi.mtd=4,2048 root=ubi0_0 rootfstype=ubifs mem=32M@0xc0000000 mem=64M@0xc4000000'
U-Boot > saveenv
  I& d1 G9 x9 ^4 V: G; J

! v! g9 n: D3 ]( K2 n请问这是笔误还是从SD卡启动和从NAND启动内存大小设置不同？
另外我设置从NAND启动 内存大小为128M，在 rc5.d中创建s99restart脚本，内容为
3 K% ]4 z2 J4 N5 R" R8 }sleep 5
reboot
意图是通过不断的热启动来验证系统UBIFS对NAND的读写是否稳定，但是发现会概率性出现以下的段访问异常错误，掉电重启后又恢复正常，
内核版本为创龙提供的2014.11.15的版本，请问这会是什么原因导致的，错误信息如下：
