Hi,I'm using AT91SAM9260-EK to develop prototype of a Thermal Printer. I'm using the MDK3.50 & ARM-RL3.50 and AT91SAM9260-EK code example as framework of my project. The problem is with the scatter-loading or variable initialization. When code size(including const data like fonts etc) is less then the scatter-loading works fine but when I increase the size of code adding some more function, big arrays of constant data etc then the scatter-loading malfunctions. Since the scatter-loading, variable initialization, copying data from ROM to RAM all are done by library functions I don't have control over it and can't able to debug where is the mistake..
Pls suggest me what should I do in such situation. Thanks
Have you sent an official support request to Keil?
This is an end-user forum, so the Keil staff may not notice this thread.
You have a link "Support" at the top of the web page, and a link "Contact" at the bottom of the page.

If ignore the above, and only focus on the below.

Program execute properly till BL __main (in AT91SAM9.s), after that it could not reach to int main(void), rather it reach to sys_exit() in Retraget.c.
(I don't know much about this.)
Just another shot in the dark:
It sounds like a Stack/Heap Size problem to me. Please make sure you provide enough space for your Stack/Heap.
On some chips, you can get into troubles with the watchdog - if it is activated in the startup file, it may take too long to reach main().
