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：
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：
U-Boot > setenv bootcmd 'mmcinfo;mmc init;fatload mmc 0 c0700000 uImage;bootm'
# t, A; P( |5 [: N. O U-Boot > setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=128M
* D7 r- C( W8 R) m9 Q
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。
3 l* `+ r4 g+ W; u* t% W# vU-Boot > setenv bootcmd 'nboot.e 0xc0700000 0 0x120000; bootm'
# G* ?! k% F5 s% A0 v3 ]% D. UU-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
/ T# U' A- p0 [( V+ ]0 S3 w& y$ y

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？
* _) b+ ^+ e/ _1 s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
sleep 5
% Z  j/ X/ M$ W7 c0 Rreboot
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：
