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.

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? ________________ Attachments : cstartup.s79 : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I1FQ&d=%2Fa%2F0X0000000bmQ%2Ff7YEj_GeFEAUDfCEoAV_M8sXD.0gwvT2oRNESA0iqEs&asPdf=falselnkarm.xcl : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I1OL&d=%2Fa%2F0X0000000bmP%2Fbt7wBT3ZdRmkAXO1EouTIF6hMxYrVVADDV4Zr5aAIOY&asPdf=falsemain.c.bak : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I1HB&d=%2Fa%2F0X0000000bmM%2FsYtSg77p5z3A4G0U2IcX_gt1dgYQp4IkHiTfgTGM_JY&asPdf=falsevect.s79 : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I1OG&d=%2Fa%2F0X0000000bmN%2FW.Q77pyTzlvTW83txW12XF.BbO2GqzMvaYa9tIlpmOg&asPdf=false
