Linker Error: Related to ENTRY Point

Note: This was originally posted on 31st August 2010 at http://forums.arm.com

Hi all,

I am using --entry=startup option with the armlink command.
The command I am using is:-
armlink --cpu=cortex-m3 --entry=startup --scatter=xyz.scat -o abc.exe def.o abc.o --diag_suppress 6238

I get the following error:-

Error: L6204E: Entry point (0x00000290) does not point to an instruction.

In my assembly code, I have:-

        AREA ||.text.startup||, CODE, READONLY, ALIGN=2
label0
startup
        DCD      0x00000000
        DCD      label1
        DCD      label2
        DCD      label2
        DCD      label2
...
...
...

My scatter file has the following contents:-

LOAD_REGION 0x00000000 0x00200000
{
.text +0
{
*.text.startup (+RO)
* (+RO)
}

.data +0
{
*.data (+RW)
* (+RW)
}

.bss +0
{
*.bss (+ZI)
* (+ZI)
}
}

I am using RVDS 4.0 on a Win XP with cygwin environment.

Please guide me with this.

Regards

LOAD_REGION 0x00000000 0x00200000 { .text +0 { *.text.startup (+FIRST, +RO) * (+RO) } ... } but had the following error:- "rtecdc.scat", line 5 (column 19): Error: L6234E: FIRST must follow a single selector. probably the *.text.startup selector is matching multiple sections. What should be done?

I think you've got the input section syntax confused. Do you want to be using

[code]
* (.text.startup, +FIRST)
? The * is matching the object file name and the stuff inside the "()"s specifies the sections from that object file.

Likewise, these two look confused:
... *.data (+RW) ... *.bss (+ZI) ...

They can probably just be removed since the line following each one is sufficient.

According to the docs [url="http://infocenter.arm.com/help/topic/com.arm.doc.dui0493a/CJAJJGEH.html"]http://infocenter.arm.com/help/topic/com.a...a/CJAJJGEH.html[/url] you can only have one section marked +FIRST.
