Re: [ECOS] HELP with target.ld file syntax...SOLUTION

Re: [ECOS] HELP with target.ld file syntax...SOLUTION

[Leo McManus]

Added ram2 to the MEMORY in my target.ld:

 MEMORY
{
    ram  : ORIGIN = 0x0000000,   LENGTH = 0x800000
    ram1 : ORIGIN = 0x0000000,   LENGTH = 0x800000
    ram2 : ORIGIN = 0x80000000,  LENGTH = 0x800000
}

and my usb_buffs to my SECTIONS

SECTIONS
{
...
...
...
    .fixed_vectors 0x20 : { . = .; KEEP (*(.fixed_vectors)) } > ram1
    .usb_buff 0x80000000 : { . = .; KEEP (*(.usb_buff)) } > ram2
...
...
...
}

the attribute Gregoire mentioned to my C file:

uchar    ECHO_ENDPOINT_BUFFER_1[1000] __attribute__((section(".usb_buff")));
uchar    ECHO_ENDPOINT_BUFFER_2[1000] __attribute__((section(".usb_buff")));
uchar    ECHO_ENDPOINT_RECV_BUFFER[1000] __attribute__((section(".usb_buff")));

and now my map file reads:

.usb_buff       0x80000000      0xbb8
                0x80000000                . = .
 *(.usb_buff)
 .usb_buff      0x80000000      0xbb8 myFile.o
                0x80000000                ECHO_ENDPOINT_BUFFER_1
                0x800003e8                ECHO_ENDPOINT_BUFFER_2
                0x800007d0                ECHO_ENDPOINT_RECV_BUFFER

Perfect...(before testing :)

Thanks

Leo

Re: [ECOS] HELP with target.ld file syntax...SOLUTION

[Richard.von.Lehe]

I am interested in this discussion and have a question about your 
solution.  Are you editing the actual target.ld file or are you editing 
the mlt_xxx_xxx_xxx.ldi file that is used to generate the target.ld 
file?  Based on the syntax it looks like you are talking about the 
actual target.ld file.

Is this a safe practice?  In other words, when does the target.ld file 
get re-generated?  If it does, won't you lose your changes?  I don't 
fully know how this all works - hopefully you can straighten me out.

Regards,
Rich von Lehe

Re: [ECOS] HELP with target.ld file syntax...SOLUTION

[Leo McManus]

I have generated an eCos library and am just linking to it, so am not
regenerating, (which I didn't know it did), the target.ld file. You are correct
and I am modifying the target.ld file, but I will look at the file you have
mentioned...if I can find the bugger..and see how my mods would be addable!

Thanks

Leo

RE: [ECOS] HELP with target.ld file syntax...SOLUTION

[Robert Cragie]

Another way of doing it is altering the architecture .ld file (e.g.
hal/arm/arch/current/src/arm.ld) and add a

#define SECTION_ram2(_region_,  _vma_, _lma_)

part. You can then include this in your mlt_xxx.ldi file so target.ld will
always be generated properly. The MEMORY part is already in the mlt_xxx.ldi
file.

There may also be a way to do it like this specifically for a platform but I
haven't figured it out yet.
