I have just started writing assembly code. I am using the simulator in Keil uvision5 to the run the code below. I dont understand why I can't see the src data value of 14 in register r1 when I ldr the data value from the address stored in the r0 register. I have tried to research the solution myself but cant find an exact reason why this happens. Any help would be gratefully appreciated.
THUMB AREA RESET, CODE, READONLY EXPORT __Vectors EXPORT Reset_Handler __Vectors DCD 0x20001000 DCD Reset_Handler AREA Code, CODE, READONLY ENTRY Reset_Handler LDR r0, =src LDR r1, [r0] terminate ; sit in an endless loop B terminate ; data area that can be modified (readwrite) AREA Data, DATA, READWRITE src DCD 14 END
