Hi serenissimo,

Actually Astfin and Switchfin uses similar memory model.
Part of the SDRAM is used for Linux file system.
We have /persistent folder mounted on NAND flash for persistant storage of configurations, sound prompts and some simple logs.

NAND flash we have on our targets however is not good for frequently
write/erase so we had no other choice then using SDRAM.

Please let me know if this answers your question.

Best Regards

Hi serenissimo,

In Switchfin we have decided to put the root file system (currently around 18MB) in RAM memory for fast easy access and stable operation of the PBXs.

So now we have 18 MB less then BAPs

              total         used         free       shared      buffers
  Mem:        41736        33080         8656            0          704


If you need to load many applications you may get shortage of RAM so you will need to put some parts of the rootfs on persistent (NAND storage).
You can check /etc/rc on the target to see how /persistent is mounted and get the idea how to do this.

Please let us know as you get some results.

Cheers.
