Run a USB application while booting the system, before GRUB starts executing
I have small display board connected to my PC on its USB port. I have developed an application which displays a string over it. I want to run this application automatically when my system boots up. Also it should execute before GRUB.
I tried to search if there is any system file, where in I can make an entry of this executable(of my application), so that it will run when the system boots up, and that too before GRUB.
I have created a Makefile for my application.
I am not getting any clue, to how to go for it.
Please help me in this respect.
Now I have downloaded grub source code and i have done a little change that i have inserted my own code in it. now i am trying to compile the grun source code. However it has certain specifications, like gcc and binutils versions. it requires, gcc version more than 2.95. I have gcc version 4.4. so i think it should work. Also, i have binutils version 2.10, however i am not able to compile binutils 2.10 as it is not supported over host=i686. I am stucked here. How to go for it now?
Please help me out.
I want to run my own application (BSP) from USB dongle. This BSP should get called when BIOS execution is done. I can specify boot from USB option and direct the boot up sequence to USB. However, how can I run the BSP at this stage. Also once BSP execution is done, the same BSP should call the GRUB and shoul continue further execution.
