Hi, In the Linker Descriptor file, we have a SECTION called Output section. In this all the Text, data and bss segments are defined. In text segment i didn't understamd *(.glue_7) and *(.glue_7t). Can any one tell me what are those two????
SECTIONS { . = 0; /* set location counter to address zero */ startup : { *(.startup)} >flash /* the startup code goes into FLASH */ .text : /* collect all sections that should go into FLASH after startup */ { *(.text) /* all .text sections (code) */ *(.rodata) /* all .rodata sections (constants, strings, etc.) */ *(.rodata*) /* all .rodata* sections (constants, strings, etc.) */ *(.glue_7) /* all .glue_7 sections (no idea what these are) */ *(.glue_7t) /* all .glue_7t sections (no idea what these are) */ _etext = .; /* define a global symbol _etext just after the last code byte */ } >flash /* put all the above into FLASH */ .data : /* collect all initialized .data sections that go into RAM */ { _data = .; /* create a global symbol marking the start of the .data section */ *(.data) /* all .data sections */ _edata = .; /* define a global symbol marking the end of the .data section */ } >ram AT >flash /* put all the above into RAM (but load the LMA copy into FLASH) */ .bss : /* collect all uninitialized .bss sections that go into RAM */ { _bss_start = .; /* define a global symbol marking the start of the .bss section */ *(.bss) /* all .bss sections */ } >ram /* put all the above in RAM (it will be cleared in the startup code */ . = ALIGN(4); /* advance location counter to the next 32-bit boundary */ _bss_end = . ; /* define a global symbol marking the end of the .bss section */ }
Thanks in Advance.
