Getting error while compiling ".s" assembler file in CCSv5.1.0.09000

Other Parts Discussed in Thread: OMAP-L137

Hello,

I am trying to compile my project in CCSv5.1 (Version:5.1.0.09000) but i failed to do so. As

it is giving errors in ".s" i.e. assembler files saying it as illegal mnemonics although while creating project

i had selected device type as ARM9 (I am working on OMAP-L137) and this project i am using as a static library.

Below are the statements where i am getting error:

.type

InsureCPU_Env, %function // illegal mnemonic specified

swi 0x0 // Comment field value must be an absolute constant

.arm // expected a declaration

orrne r2,r2,#0x80 // '#' not expected here

what is .arm means for...?

Although, this project is successfully compiled in Code sourcery.

Do i need to set any options in Assembler options? If so then please help me in that...

Thanks,

Priya

Hi Priya --

Are you trying to use the TI compiler/assembler on an gcc assembly file? Some of the assembler directives are different between the 2 and you will need to make some minor changes to the source code for the TI assembler. The TI assembly tools guide should help summarize the directives.

TMS470 Assembly Language Tools Users Guide

See related post -- http://e2e.ti.com/support/development_tools/compiler/f/343/p/141731/513163.aspx.

Yes, i am trying to use TI compiler on an gcc assembly file (CCSv5.1).

I am going thorugh the User guide provided by you to modify source code for the TI assembler.

But as per this guide ".arm" should not give the error but still i am getting error for it stating that

"#171 expected a declaration"

Regards,

Priya

Hi Priya --

Can you attach the source file to this thread? I'm going to ask that this thread be moved to the compiler forum as this seems to be a compiler/assember question and not a BIOS question.

Thanks,

.type is not a supported TI assembly directive, and I can't quite tell what it does in GCC assembly, so I can't recommend the correct one. SWI needs a constant, which would be specified with as #0x0 in TI assembly, aka " SWI #0x0". The .arm directive and the orrne look fine, just make sure each line begins with either a label or else a space as required for the proper format. For example, this assembles fine for me (note leading spaces):

%> cat example.s

        swi #0x0
        .arm
        orrne r2,r2,#0x80

Hello Karl,

Attached is the ".s" file which is giving error while building the code.

Please carry on with moving this thread to compiler forum.

I took a brief look at one of those assembly files. You need to do quite a bit to get the TI assembler to accept it. /* Comments like this */ are not accepted. Every directive needs to be changed. And I would not be surprised if you need to add a few directives. The details on the language accepted by the TI assembler are in the Assembly Language Tools User's Guide.

Thanks and regards,

Thanks, Gerorge my problem is resolved now i went through the Assembly Language Tool User's Guide.
