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：
" A; [ ?* \3 r) `! p( A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! m% q% c( c% nU-Boot > setenv bootcmd 'mmcinfo;mmc init;fatload mmc 0 c0700000 uImage;bootm'
3 ~: t3 v( A1 c8 m% I; s- F U-Boot > setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=128M9 T3 n( _8 A: p+ w. ~
8 \, F: D, Y/ U6 M( Z+ K" g0 P从FLASH启动：6 _+ f( b! W& i: h* Y( O# q
在U-Boot命令行执行以下命令来设置为NAND FLASH启动系统。 5 S1 y0 I" h2 w: w# o
U-Boot > setenv bootcmd 'nboot.e 0xc0700000 0 0x120000; bootm' 2 t/ _. F+ E7 J$ \* r* v: C
U-Boot > setenv bootargs 'console=ttyS2,115200n8 ip=off ubi.mtd=4,2048 root=ubi0_0 rootfstype=ubifs mem=32M@0xc0000000 mem=64M@0xc4000000'4 Q7 s4 b% j5 n- M5 ~/ n
U-Boot > saveenv
9 i, F0 J. k. G! |6 R9 K$ Y7 a3 _3 h* F0 y9 y
9 e7 @) j8 s5 u& h
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？$ `7 K, s2 v; W0 r
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
: E( ~7 Q5 W# x. }sleep 5
0 F0 [' k1 }0 O6 _. k# o3 l0 Rreboot8 `2 ?8 M3 R; c) e$ p6 p
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，% T3 K. z; s5 B3 s4 k7 \2 r0 l
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：# N; R0 s1 C3 g# B b- B
