The easy way to boot Linux from NOR Flash is to replace the Linux kernel file already provided on the board (named ‘/SOFTWARE/Image’).
1. Copy your Linux kernel image into the Juno NOR Flash by connecting the Juno board to your host machine using a USB cable connected to the “USB configuration port” (http://community.arm.com/docs/DOC-8393#jive_content_id_Back_panel). When you start the Juno board, the Juno board should appear as a USB mass-storage on your host machine.
2. After copying the file, ensure you un-mount the USB mass-storage on your host machine and reboot the Juno board.
3. Your new Linux kernel image should be ready to be booted by UEFI
FYI, the Juno board has a micro-controller that writes the files copied on the USB mass-storage to the NOR Flash following a specific file system (what named as ‘ARM BootMon File System’). UEFI recognizes this file system format.
Let me know if you need more information.

Hi,
I want to boot Linux from NOR flash. I see that ARM juno board is using BootMonFs file system on NOR flash.
How to create BootMonFs on NOR flash? Is there any other option available to use NOR as a boot device?
Thank you, Jayanthi
