hi3519v101 sdk demo 系统异常

升级uboot &kernel & rootfs后，在demo板上上电启动，发现系统运行异常，异常log如下：

环境配置如下:
#define CONFIG_BOOTCOMMAND “sf probe 0;sf read 0x82000000 0x100000 0x400000;bootm 0x82000000”
#define CONFIG_BOOTARGS “mem=768M console=ttyAMA0,115200 root=/dev/mtdblock2 rootfstype=jffs2 rw mtdparts=hi_sfc:1M(boot),4M(kernel),27M(rootfs)”

有哪位大神知道这是什么错误？ 如何解决？

ps:
经过两天的折腾。现在已经搞定了。然来是烧录的时候，指定的kernel长度有问题。之前指定3M，应该是4M。然后烧录后启动就正常了
