If I use Nucleo-F446RE as target, os5 is only 16.0kB but os6 is 127.3kB.
I modified the program “Serial” to “BufferedSerial” and a timer read function(Chrono usage).
In the beginning, I thought “BufferedSerial” uses big buffer RAM but nRF52-DK does NOT consume on same program.
Is this linker script problem?
Program:
IDE:
On-line compiler
Additional information:
Mbed Studio 1.10 + Nucleo-F446RE
—os5.15.0
Total Static RAM memory (data + bss): 16425(+0) bytes
Total Flash memory (text + data): 89174(+283) bytes
—os6.2.0
Total Static RAM memory (data + bss): 16642(+217) bytes
Total Flash memory (text + data): 82659(-6515) bytes
Current online compiler defaults to OS5 rev.7088 ?
I think its been wound back because of issues.
I have been using 6.2 on Studio off-line and testing Studio on-line.
Both appear to working correctly with a F767 and I have compiled for the F446 (Studio offline) and this was the result.
Looks normal to me and I’m using quite large buffers.

Hi Paul,
Thanks your answer.
I understood that online compiler is still OS5 not OS6.
I will wait official os6 release announcement from arm.
In the past, online compiler is a center of gravity but right now Mbed world is dramatically changed and I cannot understand all of the changes.
Priority for maintenance online compiler came lower.
For beginners like me, I believe online compiler is best entry way.
If someone starts the Mbed world today, how to feel current Mbed world.
Anyway, this is not this subject .
Kenji
ps:
Mbed Studio, I also confirmed seems okay as above.
