/bin/sh: ./mkfs.jffs2: not found
The './' part tells it to search for command in current directory. mkfs.jffs2 is inside initfs_flasher/ directory of initfs flasher


These steps will make jffs2 image directly flashable by linux flasher over usb or by mtd-utils (flash_eraseall, nandwrite) when running from device.
