Hello everyone,

I have been working about iap, but could not success yet.I modified the IAR source for my project in KEIL (on MCBSTR9 board). I used a button instead of joystick to jump the menu. Then I hit ''1'' for sending the .bin file. And I take ''verification failed''. I attach my project. Can anyone help me ?

Thanks.

mikhailm, thanks your reply. You are exactly right. But i am using the limited (free) version of uVision. So i did not read in flash. And when booting bank1 i can not use debugger.

First step would be to verify if you are burning code into the flash correctly.

Read it back and verify that it is burned correctly. You can also use debugger to look at the flash context.

Well.... I looked into you project

if nothing else you still have no files loaded into RAM.

other note:

you still using .h files from standard library location. Since you have to modify 91x_fmi.h for bootloader one way and for ''real'' program other way this isn't a good idea.

You want to copy all ''modifiable'' .h files into the corresponding project folders.

I also don't see BOOT_BANK1 defined for assembly files...

I suggest you reread everything that was posted in this thread. I was following the advice and managed to make it work...... through ENET, not serial port.

I think that is exactly what your problem is..... I don't remember exactly what the issue with ''free'' version of uVision is, but I couldn't make anything to run from Bank1.

even the LED blink demo.......

EDIT:

and I remember that I even received an email from Keil confurming such limitation on limited version

mikhailm, i follow the KEIL's instruction:

http://www.keil.com/support/docs/3347.htm

Then i can boot from bank1. My iap application is working from bank1 now.

(i attached it before in this title.)

I also have to ask KEIL support about limitations.

Thanks.

I changed my code following the KEIL's instruction before, but i could not attached at that time. Now, i attached it.

The .h files are in standart libarary location, it is correct. But when i want to compile ''real'' program, i uncomment #define Remap_Bank_1. So, i understood your advice but i think the problem is not about that.

Can you give me some advice about the real program config ? Or may be a sample project.
