ChibiOS Free Embedded RTOS

When I compiled the /RT-STM32G474RE-NUCLEO64 template, the compilation result showed that the running memory(RAM) occupied 128K, what should I do to reduce the running memory consumption? Because the STM32G474RE only has 128K of running memory (I'm a newbie, excuse me)
The result of the compilation：
text data bss dec hex filename
7588 0 131072 138660 21da4 build/ch.elf
Creating build/ch.list


RAM(/K) = (bss+data)/1024 = 131072/1024 = 128K

Hi,

It shows it as fully used but it is not really the case, all the unused RAM is "used" as heap for memory allocation.

For the statically used RAM see the generated .map and .dmp files.
