Hi guys,
I've just finished a design of a board using MKM34Z256VLL7 and regretfully cannot program/debug it.
The SWD interface seems simple enough - all that it requires is Vtarget, GND, SWDIO and SWCLK.
However, I am not sure if it makes a use of RESET pin. Another thing is that the analog section on my
design is powered down.
So, I've got 2 questions:
1. Does SWD require RESET pin connected?
2. Does the micro have to be fully powered up, including the analog section in order to be programmed?
I presume it starts up with an internal oscillator (from the data sheet).
If anyone has any ideas please share...
Thank you very much.
Well, turns out I used wrong pin out for my j-link programming adapter...
Now, I guess, we know that the RESET pin is not required for SWD
and it does not matter if the analog section of the KM family powered
down.
Cheers.
