linker command file - Memory pages

rajanikanth g
Intellectual 520 points


Hello,

I observed that program memory has been allocating in PAGE 0 itself  in linker command files of some applications running on c55x and c64x+ platforms.

Is it mandatory to allocate all program memory sections in PAGE 0 itself ?

What is the concept behind different pages of memory ? Is it only for readability sake ?

Thanks in advance.

Thanks and Best regards,

Rajanikanth.

    Please see this wiki article.

    The most common case, by far, is to not specify any PAGE at all.  In that case,  PAGE 0 is used.

    I have seen use of PAGE 0 and PAGE 2 on some c55x systems.  That's because most (or all?) C55x devices have address space dedicated to I/O ports.  In the link command file, that range of addresses is modeled on PAGE 2.  I have not seen a C64x+ link command file use PAGE.

    Thanks and regards,
