ubnutu文件无法挂载，日志如下Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)CPU: 2 PID: 1 Comm: swapper/0 Not tainted 4.9.37 #87Hardware name: Hisilicon HI3559AV100 DEMO Board (DT)Call trace:[] dump_backtrace+0x0/0x1d0[] show_stack+0x14/0x20[] dump_stack+0x94/0xb8[] panic+0x130/0x280[] mount_block_root+0x22c/0x2e8[] mount_root+0x74/0x84[] prepare_namespace+0x164/0x1a0[] kernel_init_freeable+0x1c0/0x1e0[] kernel_init+0x10/0x100[] ret_from_fork+0x10/0x30SMP: stopping secondary CPUsKernel Offset: disabledMemory Limit: 512 MB—-[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) emmc介质启动参数设置如下bootargs=mem=512M console=ttyAMA0,115200 root=/dev/mtdblock3 rw rootfstype=ext4 mtdparts=hinand:1M(boot),9M(kernel),5120M(rootfs)

现在i2c设备挂在主控soc的sensorhub上，dev下只看到i2c0到i2c11，没看到sensorhub相关东西。量SDA跟SCL只有高低电平，没有波形。按照海思提供的  外围设备操作指南的 1.1 Sensor Hub外围设备操作指南 1 改内核配置选项，勾选M7 2修改dts文件，修改文件hi3559av100.dtsi的i2c_bus12，就是对应的shub0,从disabled改成okay 3在uboot环境配置Sensor Hub时钟。执行“config_m7”命令配置时钟 4根据Hi3559AV100_PINOUT_CN配置管脚复用。管脚是AJ3为SCL和AJ1为SDA。执行 himm 0x18050024  0x1403  himm 0x18050020 0x1403 两个命令复用管脚 5编译内核，烧录 请各位大佬指点
