relocate UNINITIALIZED sections

Regarding the specific question in the previous post of how to locate _c_int00 at a specific address, you can use this syntax to get it exactly where you want it:

SECTIONS
{
    .text:_c_int00 : 0x200000

    - or -

    .text:boot : 0x200000 { rts64plus.lib<boot.obj>(.text) }
}

If I understand correctly, however, you really only need it to be aligned to a certain alignment; try:

SECTIONS
{
    .text:_c_int00 > PMEM, align(4096)
}

Yes, the linker does reorder the sections to try to pack them into memory more efficiently. If you want to force a certain order, you'll need to use a GROUP:

SECTIONS
{
    GROUP
    {
        .text
        .cinit
        .data
        .const
        .bss      
        .stack
        .switch
        .far
    } > IRAM
}

I want to locate all the UNINITIALIZED sections at the end of memory map, but when I use HIGH directive then sections are as I want but program doesn't work.

When I place HIGH directive at .data or .bss section EDMA of IVA doesn't work right. When I place HIGH directive at .stack section program doesn't work at all.

How to locate UNINITIALIZED sections at the end of the memory map?

I'm sorry, I don't know of any way to instruct the linker to sort uninitialized sections after initialized sections, although this seems like a reasonable feature to request.

Using HIGH should not affect the correctness of the program.  Can you be more specific about the problem you are seeing?  Does the linker give you an error message?  Does the linker honor the HIGH request?
