I would like to detect if a reset happened due to a brownout or an actual power off. I tired so far using the GPREGRET and RESETREAS registers. They are useful to detect soft resets and distinguish between their causes, but since they are cleared on…

Hi, We have an application that can run in two modes. The mode is selected by setting the GPREGRET to 1 or 0 and restarting. Currently we are running this procedure directly via jlink commander, but we want to convert it to python commands. Using the…

I'm trying to use gpreg for state across toggles of nRESET. I thought it was working, but when I tested it on hardware without jtag connected it seemed that gpreg was getting reset as well. Before I go down the path of trying something else, should…
