Hello ,
I am using the C6748.
I need to perform a special boot sequence.
At power-up i need to load a loader(programmer) application from flash.
This is an application which communicate with a PC host via RS232 with a specific company protocol and can program the flash with SW images or other data.
I need this application to run only if 2 IO pins are set to a certain state. if the IOs are set to another state than i have to load the "operational" application (not the loader application).
So what i would like to do is :
burn 2 images to the flash.
1) image at the start of the flash which holds the loader application code.
2)image in another place in the flash which is the operational application code.
the first image (boot image) is loaded first , read the io discretes and decide if to "stay" in the loader application or jump to the operational application.
I think i can do it only if i could tweak the AIS decoder so it would jump and parse another AIS image if the IO discretes are set to operational code.
Does anyone has a clue how to chage the return point of the AIS decoder from its "JUMP Command - 0x58535905).
Thanks ,
Eran.
