Summary0000812: [common] check memory usage. consider to reduce memory size.
DescriptionHi kerwin

we have to consider to reduce Memory size.
for checking it, please give a guide and a current memory map each Smart3 , UHD4.
I checked memory usage via / proc/meminfo and dumpysys meminfo for favorite channel and multivew .
but free mem have a large space. I think so this result is wrong for checking memory leak.
please give a guide about this agenda.

Thanks

Hi kerwin

I think below information is useful to judge about memory usage.
as a result, Case Smart3, Free Mem is about 700MB , Case UHD4 , it is about 1.1GB for Multiview.
So Do you think UHD4 possible to work in 2GB and smart3 is impossible in 2GB.

Hi Mr. Yoon and Mr. Jason Park,

I provide memory map of eMMC and DDR for both Smart3 and UHD4 model.
The memory map for both model is the same.

For run-time memory usage, I suggest to have more tests under complicated scenarios.
For example, playing multiview + BT audio on RCU + NUGU..etc.
I am not sure which APP needs more memory.
Therefore, I think this may need TVS or Digicap's help/

BTW, the DDR size is hardcoded in bootloader wchich means it is impossible to have one FW for different DDR size.
