console's Issues

Console access

I am trying to get command-line access to a firmware that I am running using firmadyne. The process I am following is:

# Using firmware-mod-kit
./extract-firmware.sh FW_RT_N15U_30043763754.trx

mkdir FW_RT_N15U_30043763754/rootfs/firmadyne

mknod -m 666 FW_RT_N15U_30043763754/rootfs/firmadyne/ttyS1 c 4 65

cp console FW_RT_N15U_30043763754/rootfs/firmadyne/console

# Using firmware-mod-kit
./build-firmware.sh FW_RT_N15U_30043763754

When I try to run the firmware it fails to start and in qemu.initial.serial.log I find:

"Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)"

I saw the FAQ on the main firmadyne README that mentioned an issue with kpartx and to try increasing the timeout in inferNetwork.sh and deleting the scratch directory but neither seemed to resolve the issue.

Is this the correct process for setting up the console?

Also of note, if I extract the firmware and re-build it again using the firmware-mod-kit, omiting the modification steps, the firmware loads up and runs properly.

kernel panic - not syncing: No init found.

I try to follow the usage to run a firmware.I run the example successully.But when i try to start another firmware.It's always have no Internet interfaces but without any error in the step of generating run.sh. when I run the run.sh,the error is:
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended
[ 2.472000] VFS: Mounted root (ext2 filesystem) on device 8:1.
[ 2.484000] Freeing prom memory: 956k freed

[ 2.544000] Kernel panic - not syncing: No init found. Try passing init= option to kernel.

I deleted the image file and try again but still not work.
