Posts: 15100 		Anyone know the value of CP15 register 0 for the A9home's CPU, or some other reliable way of working out whether code is running on an A9home?

If anyone owns an A9home and doesn't know what I'm talking about, this short BASIC program should (hopefully) tell you all I need to know:


DIM code% 128
P%=code%
[ OPT 0
SWI "OS_EnterOS"
MRC CP15,0,R0,C0,C0,0
MSR CPSR_c,#0
MOV R0,R0
MOV PC,R14
]
A%=USR code%
PRINT ~A%


Cheers!

OS_ReadSysInfo 8 is your friend.
