I compile my program and observed huge RAM consumption as below.
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?
Mbed Studio 1.10 + Nucleo-F446RE
Total Static RAM memory (data + bss): 16425(+0) bytes
Total Flash memory (text + data): 89174(+283) bytes
Total Static RAM memory (data + bss): 16642(+217) bytes
Total Flash memory (text + data): 82659(-6515) bytes
Thanks your support in advance.
