Hi Corey, Thanks for your reply but I am not clear. Let me list the steps, may be that will explain the problem I see. 1. I have a host target environment 2. I build Linux Kernel image with initrd on the host 3. I also build the root file system on the host 4. Now I build Linux BIOS and specify the Linux Kernel as payload. 5. So at this point I have the .bin/.rom for Linux BIOS and an image file for the root file system. 6. So my question was how do I get this on the flash device. Do I have to use an external programmer for this ? Because there is nothing on the target for me to run flashrom.
