Part Number: TMS320DM8148
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI C/C++ Compiler

hello ,

We are working with the dm8148 DVRRDK_04.01.00.02 .

I am developing sw in the dsp 674x in the dm8148 , under ccs 5.5 and use sysbios and syslink .

We need to use "Noise suppression" lib from other company .

The project is compiled in ELF format .

When performing the link phase with the specific lib we got the error :

dspini_ncse.l64p<basop.obj , built with --mh=auto option is not allowed !!

How we can overcome this problem .

Does it meen that the lib was compiled with "speculative load" .

We use syslink , is this the lib in our project that conflicts in that matter ?

Hello George ,

Thank you for your answer .

I looked at the info you provided and it helped a lot .
In It it was found that the flag "--mh=auto" is not allowed for dynamic linking .

But , my project , that uses syslink , entered ' --dynamic' flag in the 'link.cmd ' file .

How can i build my project and syslink without specifying the '--dynamic' flag ?

Regards .

I don't know why your project needs to use the linker flag --dynamic. I'll get some TI-RTOS experts to comment on this aspect of this thread. That said, it is a good guess that --dynamic cannot be removed, which in turn means you cannot use --mh=auto.

Thanks and regards,

Hello Shlomo,

The "--dynamic" and "-retain=_Ipc_ResetVector" flags are automatically added to the linker options when the .cfg file contains "xdc.useModule('ti.syslink.ipc.rtos.Syslink')."

You may be able remove the syslink specification in the cfg file and manually add the required libraries as done in the following thread.

Hello George and shahin ,

We have already received a library that the flag "--mh=auto" was omitted from it .

I will look also at shahin info .

Thank you very much for helping us undertand and resolve the problem !!
