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：4 G/ y9 }- e" ^: ?' l. ?
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： + F7 X0 \: V U( `
U-Boot > setenv bootcmd 'mmcinfo;mmc init;fatload mmc 0 c0700000 uImage;bootm'$ c% c: z$ V- o9 J+ o
U-Boot > setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=128M$ C6 ~5 W M# {' i9 r
( s. _$ E. ~1 q/ ]1 i
从FLASH启动：- D' Q1 M. u6 I+ j* O0 D, {* P5 p8 N
在U-Boot命令行执行以下命令来设置为NAND FLASH启动系统。 ( ^. j4 f5 k& z- o# g) q, Q
U-Boot > setenv bootcmd 'nboot.e 0xc0700000 0 0x120000; bootm' ! A1 b1 n% y! z8 x: X( i
U-Boot > setenv bootargs 'console=ttyS2,115200n8 ip=off ubi.mtd=4,2048 root=ubi0_0 rootfstype=ubifs mem=32M@0xc0000000 mem=64M@0xc4000000'
# K/ ?" F9 f$ h8 k e" ?3 b U-Boot > saveenv6 y5 y- O# ?2 J. s. S& o O2 g
2 p0 `( X" a; T! M+ j1 L' X- b
; T* q2 Q# r0 Q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？( Q$ q: R* T, h; ]* B8 ~
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 # C& ~* c" ^: k4 ~3 _
sleep 5( F- x) @; I, ^6 L6 i2 F6 E
reboot
; \9 l+ m9 O7 I& `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，1 n* c" V5 V7 z
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：
