Starting a user program from the Pre-loader.

[Altera_Forum]

Hi, 

  I had generated the preloader image by following the steps given in  http://rocketboards.org/foswiki/view/documentation/gsrd131preloader  I had programmed the preloader file using hps.exe software.  and after power-on reset the Preloader is working fine. That is I could able to receive the serail communication comments through UART.  My query is ..,   I have run an user code to blink the LED. I had written the code and compiled using ARMDs-5 IDE.   How to load the user written code after the preloader and start executing it ?????  Could you please give me suggestion or tips to execute the usercode from the preloader.

There is common way right? You may bring the path and application name to the kernel as a boot parameter for init, then kernel will only start the init process itself  

try look at this(see: http://en.wikipedia.org/wiki/linux_startup_process). Traditionally this application then handles starting daemons, geTTYs, etc.  Most boot loaders allow you to specify a path for the init app as part of the configuration for where to find the kernel.  as example:- /boot/vmlinuz-n.n.n init=/path/to/theapp
