- Subject: [ECOS] moving functions into RAM
Hi all,
I've looked through all the archived posts that mention the
Relocation truncated to fit: R_ARM_PC24
and any mention of
__attribute__ (section(
in the hope of finding any hint as to why I'm failing to link with the
above relocation error.
I'm trying to ensure that a function is loaded to RAM instead of flash.
I'm doing so by adding a section attribute to the end of my function
declaration:
void FLASH_SectorErase(u32 Xsectors) __attribute__ ((section
(".2ram.flashsectorerase")));
I get the linker errors at all the points in the source where I'm
calling the FLASH_SectorErase presumably because the BL target address
won't fit in the 24 bits available to the address. I've edited the
redboot/current/makefile to add a -mlong-calls but to no avail.
Is the linker ignoring the argument or am I missing something else?
Any info appreciated.
