内核恐慌 - 未同步：请求的 init /linuxrc 失败错误 -8

如何解决内核恐慌 - 未同步：请求的 init /linuxrc 失败错误 -8

1.BusyBox应该没问题，因为我把rootfs放在mmcblk0p6上，用raminitfs挂载mmcblk0p6后，可以手动挂载mmcblk0p6，执行所有./ls ./pwd等

2. 我使用引导参数， bootargs = "mem=4064M console=ttyS1,230400n8 earlyprintk=dw_uart,
   0x04992000 initcall_debug=0 loglevel=8 root=/dev/mmcblk0p6 rw rootwait rootfstype=ext4 init=/linuxrc
   blkdevparts=mmcblk0:512K(spl),1M(uboot),1M(dtb),32M(kernel),5M(param),128M(rootfs)";
