Hi,

IWR1443 has separated VIN_SRAM 1.2V power rail for internal SRAM.

Can it be used to save SRAM context between power off cycles?

Gennadii,

I appreciate your patience. What you are proposing cannot be done with the demo as is, due to the nature of the design to "cut" everything between power cycles. It would be a matter of re-design to have a "still powered on" version of the demo.

Brennan,

Should the firmware be changed for "still powered on" version of the demo? Should there be any kit schematic changes except separate power rail for internal SRAM?

Gennadii,

That is certainly something you could try, however, like I mentioned before, it would involve a re-design of the demo in order to account for this.

Brennan
