1. usb stick (1GB - /dev/sdb) needs to be formatted as fat32 type c

fdisk /dev/sdb

• press p to print and check if there's any existing partition
• press d to remove any existing partitions
• otherwise just hit c to create new parition
• select p to set new partition as primary
• enter to accept default
• another enter to accept default
• t to set the type
• c to set fat32
• w to write and save the config

2. after formatting the stick, don't forget to run mkfs.vfat

mkfs.vfat /dev/sdb1/

3. just run the script as root user

chmod 700 mkix2fw2usb.sh
./mkix2fw2usb.sh

4. make sure all the folders and the files need to be owned by root user and group

chown -R root:root /usb_mounted_path/emctools/
ls -l /usb_mounted_path/emctools/
ls -l /usb_mounted_path/emctools/ix2-200_images/

5. using ix2-200d_images directory doesn't work and had to change the path to ix2-200_images
