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：$ b* e* K2 ~# q5 u# J
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：
8 d2 J4 ?. s0 I* V3 p% QU-Boot > setenv bootcmd 'mmcinfo;mmc init;fatload mmc 0 c0700000 uImage;bootm'
+ E& b+ K8 u3 X! h U-Boot > setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=128M2 H% i: ~: F% Q6 t. ^5 ^8 a
' Z+ |4 @' p2 U# @0 |# W; X! u
从FLASH启动：
Z* w' M9 K% h+ i; M5 d$ ^& ~在U-Boot命令行执行以下命令来设置为NAND FLASH启动系统。 & T1 { [- s- i( e6 D& S( Y
U-Boot > setenv bootcmd 'nboot.e 0xc0700000 0 0x120000; bootm' ( g" s9 I: ^6 ^% ] `0 x
U-Boot > setenv bootargs 'console=ttyS2,115200n8 ip=off ubi.mtd=4,2048 root=ubi0_0 rootfstype=ubifs mem=32M@0xc0000000 mem=64M@0xc4000000'( ]7 ?- K! e9 M/ P; @& k
U-Boot > saveenv* S/ |- y/ B. d' c0 Y
4 j0 O8 k4 C4 w) W
* b5 S J z) e: H1 y' S. c
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 s: n4 X. Q- h( N/ z( }% y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 . H6 X( {0 _* A. @
sleep 5; B3 w0 j, z3 K0 h6 y- ^4 D- M
reboot
% d% b! H2 s* x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，
