The Toradex Evaluation- and Carrierboards support booting from a USB Flash Drive. Every common USB Stick can be used as such a device after a short procedure. The light DOS version of FreeDOS used for the device includes many DOS utilities, as well as automatic CD driver loading.

  • The latest single-disk version of FreeDos
  • A program to mount .img disk images for example WinImage
  • The latest version of the HP USB Disk Storage Format Tool for example V2.2.3
  • An empty USB Stick(any remaining data on the stick will be lost after the procedure!)

The Procedure

  • Download the latest single-disk version of FreeDos (.img).
  • Mount the disk image for example with WinImage.
  • Export the files of the image to a temporary folder.
  • Download the latest version of the HP USB Disk Storage Format Tool for example. V2.2.3.
  • Plug in the USB Stick.
  • Run the HP USB Disk Storage Format Tool.

  • Give your boot stick a name by editing the Volume label field.
  • Chose FAT32 as file system in the second dropdown menu.
  • Check the Create a DOS startup disk using system files located at: checkbox.
  • Root the temporary folder you exported the image files to.
  • Start the formating by clicking the Start button.
