Hello everyone. I'm trying to start RTEMS on STM32F407. It has only 192KB of Ram. After compile a test program i' executing arm-rtems4.11-size arm-rtems4.11-size shell.exe text data bss dec hex filename 162292 1576 195016 358884 579e4 shell.exe As you can see BSS segment is 195016 bytes long. How can i minimize it to 1 KB or to 5 KB?
