I am running a led toggle sub-routine in infinite loop for Cortex M33 on MPS2+ FPGA Board, want to calculate cycle count in one iteration.
LDR R0, =0x40302000 ;FPGAIO Base Address(0x40302000) + LED_OFFSET(0) MOV R2,#3
Loop LDR R1, [R0] EOR R1,R1,R2 STR R1,[R0] B Loop ENDP
Please assist me to do this
Thanks a lot.
