How to print memory usage in Nuclei Studio¶

问题说明¶

In order to print memory usage when compile an application, you can do it like this:

Click Nuclei Settings in selected project, and pass extra -Wl,--print-memory-usage in Extra Link Flags, and save settings, and then build this project, you will be able to see memory usage.

Building target: 050hello.elf
Invoking: GNU RISC-V Cross C++ Linker
... ...
Memory region         Used Size  Region Size  %age Used
             ilm:        8280 B        64 KB     12.63%
             ram:         64 KB        64 KB    100.00%
Finished building target: 050hello.elf

Why the ram usage here is 100% used?

For Nuclei SDK or NMSIS template linker script, the stack is placed at the bottom of ram memory, so the ram usage is 100%.

解决方案¶

Add extra link option -Wl,--print-memory-usage will solve this issue.
