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：
+ {) L5 H4 r1 H5 B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： 9 `4 Z/ o: X; S+ D0 x
U-Boot > setenv bootcmd 'mmcinfo;mmc init;fatload mmc 0 c0700000 uImage;bootm'
9 T0 q$ ?% e$ Y- \0 ` U-Boot > setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=128M& o: C! Q( t$ \! }
3 _: K% y' J, w从FLASH启动：
" U: m3 `2 P8 q9 t# v在U-Boot命令行执行以下命令来设置为NAND FLASH启动系统。
! R6 z& W6 a+ o0 O- T& lU-Boot > setenv bootcmd 'nboot.e 0xc0700000 0 0x120000; bootm' * J- [( \8 q0 `

U-Boot > saveenv
) L4 q9 y; V6 X/ M% r5 v8 h3 {! L" t" f, Y# E
! l3 d$ {' \! C: @0 }
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？' r% f* B, s4 u+ M0 Q
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
: ?& Q P; y$ |' p/ [sleep 5% E( ]9 L5 w. G" B/ M" J
reboot9 v2 Z: Z+ }7 y
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，
