On the host computer, is targetfs_a and targetfs_b is the similiar clone of each other at location:
~/nvidia/nvidia_sdk/DRIVE_Software_10.0_Linux_OS_E3550/DRIVEOS/drive-t186ref-linux
I have broken targetfs_a during cross-compilation. Is it possible to revert back the the original image by copying targetfs_b to targetfs_a?
