Hi:
We are now using the Ti-CC1110(Originally Chipcon). This MCU have a enhanced 8051 core and an RF modem(433MHz) integrated.
Because some address are mapped out for the RF modem, the 8051 core has NONE regular XDATA address. It is not mapped in address (0X000-0XFFF), but in address (0XF000-0XFDA1). As a programmer for CC1110, we are forced to modify the default XDATA map, otherwise the stack allocation will failed definitely, i.e. functions use the XDATA stack(large mode) will failed.
Then where to modify the default XDATA map?
According to my experience, there maybe THREE ways can achieve this object:
(1) Modify the default STARTUP.A51 file
(2) Modify the Device Manager DataBase of CC1110
(3) Write a project specific linker control file
I can not make sure which way is correct. I have tried method 1 and 2. But no aid at all.
If you need more information please let me informed! Thanks & Best Regards!
