SPI NOR FLASH无法挂载根文件系统

主板用的HI3516DV300,用spi nor flash 没有nand flash和emmc
nor flash的block size是64K，根文件系统是rootfs_hi3516dv300_64k.jffs2
麻烦大神帮忙看一下，我内核启动成功了，但是挂载不了根文件系统？？？？？？
ps.
setenv bootargs 'mem=64M console=ttyAMA0,115200 root=/dev/mtdblock2 rw rootfstype=jffs2 mtdparts=hi_sfr:1M(boot),4M(kernel),11M(rootfs)'  
setenv bootcmd 'sf probe 0;sf read 0x81000000 100000 400000;bootm 0x81000000'
文档里用0x82000000但是我看HiBurn的命令用的是0x81000000，经过测试，两个都可以进入内核，但是都挂载不了根文件系统。
求大神解答。
