RE: nRF5340: SRAM1 on the netwrok core

Any developments? The build is chock full of misleading things. Would be nice to know if this is also something that means nothing or not.

I wonder if this is related to the shared sram that allows IPC between the application and network cores, as defined in nrf5340_shared_sram_planning_conf.dts. That's called "sram0" though, so maybe the fact it's 64kB is just a coincidence.

Just interesting that the equivalent memory breakdown for the application core doesn't show a "sram0" or similar, yet the RAM region is only 440kB. That suggests the 8kB for Peripheral CPU DFU (shared SRAM for DFU purposes), and the 64kB for IPC shared sram has already been taken out.

Hi,

The total available RAM for the network core is 64kB, though why it shoes as two separate sections is a bit strange. I will confirm everything internally and get back to you soon.
