Bala, ; for ADS or SDT Image2Addr EQU 0x10000000 ; Put the execution address of Image2 here // for GCC #define Image2Addr 0x10000000 // Put the execution address of Image2 here ldr r0,=Image2Addr mov pc,r0 ; no-return This assumes that Image2 is linked for a particular address (here 0x10000000) Cheers, -Mike. --- balakumar chinuswamy <cbalakumarbe@...> wrote: > > I have two Images of firmware in my controllers > flash. > > Initially i will boot the image_1 which will be at > the > default reset location. > > In the middile of the Image_1(running) i have to > boot the > Image_2 . > > I have to boot the image_2 from the startup . > > What can i do to jump from Image_1 to Image_2. > > regards > Bala > > > [Non-text portions of this message have been > removed] > > Yahoo!
