Can some one guide me regarding firmware update through serial port.
The devices I am using is
1] 8051/ARM7
2] ST make flash memory M29w160ET (ST has given information about using the flash)
the memory iis only one for boot program and for application program.
I need some basic information to start with
1] how this firmware upgrade will happen when my linker file defines the code address as read only
2] What the boot loader should do
3] Any application note which is relevant to my application

Regards,
vikrant
