I did develop a bootloader for ARM9 to run from Bank1 and later switch to bank0. When I ran the same bootloader from Bank0 I could debug and test its working.

But when I changed the program to run from Bank1 (in IAR 5.10 Release Mode) its not working. Using JlinkSTR91x.exe I am changing boot bank to 1 by running the command the ''setb 1''. Then trying to load the program to flash from IAR (Release Mode). Then I tried to cycle power the ST ARM9 MCU but my program doesn't seem working.

Any ideas quickly??
