Hello to all,
In order to measure the current variation due to instruction address location. I filled the memory with NOP instructions and tried to observe the variation in the current consumption due to change in the instruction address, although the instruction is throughout same.
And as a result, I have got the current consumption, but from the captured current consumption for multiple times, I think there is some periodic behaviour is occurring, but couldn't find the instruction address on which it's beginning and on which it ends. Since the frequency of measurement is 12MHz and target processor is ARM Cortex-M4. Is there any way to find out the least current consumption on which instruction address???
Thanking you,
Regards,
Himanshu
Hi,
The easiest way is to add a small piece of code to toggle a GPIO pin so that you can co-relate the power measurement with the GPIO activities.
