Hello!
I'm trying to use the ram_retention in sdk 15 alpha to retain RAM in system off mode and do some power profiling.
The default code seems to retain 8 kB of RAM. copy and pasting the appended section of the code and replacing 0 with 1,2,3..7 did not increase the power consumption as expected.
What am I missing?
Thank you, Nishant
