1、I have run Ethernet Bootloader on my board of MK64FX512 through IAR development;
2、But my company must use Keil MDK development,in In the process of transplantation,I Encountered one problem.
I want to put the Fapp_params to address 0x7f000 in flash,so I add the scatter file
ER_m_fnet_app FappParams_start FappParams_size{
fapp_params.o (+RO)
}
bulid the project the map file show
Execution Region ER_m_fnet_app (Base: 0x0007f000, Size: 0x00000244, Max: 0x00000fff, ABSOLUTE)
Base Addr Size Type Attr Idx E Section Name Object
0x0007f000 0x0000008c Code RO 6026 i.fapp_params_from_flash fapp_params.o
0x0007f08c 0x000000dc Code RO 6027 i.fapp_params_to_flash fapp_params.o
0x0007f168 0x000000dc Data RO 6029 .fapp_params fapp_params.o
it seems that the result is ok,
but I debug the project through the J-Link online,it come in hardfault at the beginning.I donot know what is wrong?
please help me ,thank you very much!
This is my scatter file
