    Can anybody give me some pointers on how to track down the cause of this problem. All I have been able to track down is that it keeps going to the reset line in the 91x_vect.s file. Is there any way of finding out why this is?

    I am trying to get the In-Application Programming example working on our eval board using the IAR 4.42a workbench. It compiles and loads on to the board but does not get past the initialization program. When I ran the program with the debugger I found that it goes straight from program start to line 38 ( LDR PC, Reset_Addr) in 91x_vect.s. Has anyone else had this problem? If so how did you fix it?

    Did you follow the steps described in the STR9 In-Application Programming using UART application note(see attached file, section 1).

    May you need also to use EWARM4.42A.

    I am using 4.42a. The 4.3 in the first post was a typo I did not notice. Is there anything special I need to do to have the program loaded onto bank 1 or is that already set up in the project files?

    You need first to remap the bank 1 to address 0 before loading the IAP.

    You can use the JlinkSTR91x.exe utility to do this.

    See the following link:

    Hello,

    I am trying to run the IAP by usart. I could achieved to run the application for the ST's compiler systick example but i couldn't run it for any other code. I am converting the axf to bin and sending it via hyperterminal. It always fails in the 9th packet. Do you have any information about that? What must i do to use the IAP for any project.

    Thanks and Regards...
