| ### BSS sections |
| |
| When loading ELF files into the memory, only the data stored in the file is loaded into the memory. |
| Data specified by the memory size is not set. |
| This is the case for BSS sections for which only the size information is stored in the ELF file. |
| The zero-ing of this sections is the responsibility of the executed code. |
| This is typically achieved by setting symbols for the start and end of the BSS section in the linker script and zero-ing the intermediate addresses by the startup routine. |
| |
| **Requirement: BSS zero-ing must be implemented by the executed software.** |
