I select my device in the debugger, as shown in the attached screenshot. When I click on 'Start debugging', the debugging does not start. Using the simulator as a debugger, the debugging starts even without adding breakpoints. What is the issue?
After clicking on 'Start debugging'
This is my code:
start:
; To read all 10 serial bytes from the signature row, following steps must be performed:
; 1. Load the Z-pointer with the signature byte address given
; 2. Set the SIGRD bit in the SPMCSR register
; 3. Set the SPMEN bit in the SPMCSR register
; 4. Load from Z register to general register
; 5. General register now contains the serial byte
; Read Serial Number Byte 0
