I''m a newbie.

I've some questions about IAP. Hope someone can help me.

I've could not find any example code to run IAP on upsd. but i found the code for dk900. I think they are similar.

I read the code which is in the folder named ''uart1_c''. what I found is that the keypoint is in the startup.a51. Am I rigth?

the module ''RET_BOOT'' in startup.a51 is called when the upsd switch to the boot program which is located in the eeprom.

the moudle '' EXE_MAIN'' is called when the upsd switch to the program in main flash.

but i could not find any fuction has call the moudle '' EXE_MAIN''.

so i guess the code in ''uart1_c'' is the main program in the flash rom.

there must be another project file store the code for the ''boot program''.

this two program are separated, and separately write in the eeprom and flash. but they use the same startup.a51.
