Need help with IAP for IAR

Note, I'm using IAR compiler...

I'm trying to load my bootloader into flash and then on startup have the loader run from ram, but I don't think my cstartup.s and linkarm.xcl files are right. I've seen examples in the forum for realview using 71x_init.s and scat.s, but IAR doesn't use scat files.

so far I figure I need to call ?main in cstartup.s, I read that is what copies flash to ram, and then calls the main routine. How should I configure my linkarm.xcl file? and is there any other configuration settings to note?

I will be able to verify if my boot loader is copied to ram if I can sector erase Bank0 Sector 7 for example.

thanks for any help

Hallo,

I use IAR compiler with external flash, too. In the attachment you will find startupcode and IAR-configuration file using RAM and internal flash.

Regards

Jörg

thanks for the reply but im just trying internal flash now.

i've attached a simple program that is supposed to copy itself from internal flash (bank0sector0, 0x40000000) to ram (64k on chip ram)

then in the main it calls an erase bank 0 sector 7 function to verify its running in ram, not flash.

looks like im way off on this one, any pointers on how to get this to work?
