So looks like its software bug and this device have 128MB ram onstead of 233MB that was listed before ?
Honestly I don't know what is the truth. I didn't get (yet) an answer from MikroTik here or in the other topic where I asked
. I reverted back RouterBOOT firmware to 3.43, and again I see Total Memory of 233.2 MiB. So far this is my conclusion: if you have firmware 3.43, then you see more memory, no matter what is the ROS version.
On the photo
in the article
where someone disassembled the unit, I can see the memory has the label "NT5CC128M
16IP-DI", so 128M may indicate that physically it is really just 128 MB. But in the article he also noticed he has 233.2 MB. In the datasheet
of the memory it is also in the same row
where they list all 128 MB module variants. On the other hand wikidevi
initially said 128 MB, then later they edited to 256 MB, you can see in wiki page edit history.
So I don't know what to conclude here. Maybe if someone knows how to write a small script which fill in memory (just for test), then we can see if we can write there more than 128 MB or not
