Hi,
I am trying to get linker to create a variable pointer to a specfic location. If I can't get linker to do this I will have to do by just defining a "char *" and setting the pointer to an absolute location. But I wanted to do this from linker file and I think it should work.
<ProgramSection alignment="4" load="no" start ="$(FLASH_FW_REV_START)" size="$(REV_SIZE)" name=".firmwareRevisionRecord" address_symbol="__start_fw_revision_record" />
but linker seems to create a loadable section....

I expected the load="no" to supress loading of this section.
