Hello everyone,
 
I am executing my program from flash memory, but I would like to relocate the IRQ vector and the code of the handlers (uart0_handler, timer0_handler,...) in RAM, so I won't miss incoming data from the UART while writing the internal flash using IAP routines.
 
I am using the GNU toolchain, but I couldn't find examples or documents about how to achieve this.
 
The parts I would like to relocate (IRQ vector + handlers) are written in assembly (actually it is Ashling's startup code for EVBA7), in the same section as the other vectors (reset, undef,...).
 
Do I have to relocate them all (vectors + code)? But then, the reset vector won't be anymore at address 0, and the code won't run after a hardware reset?
 
Does anyone know how to do this?
 
Thanks a lot,
 
Gilles
