Hi all,

I am trying to compile video scaling example for DM642EVM,I have imported project of ccsv3.1 to ccsv4

compilation working fine,but in linking I am getting errors regarding undefined symbols,my errors are like:

undefined first referenced

symbol in file

--------- ----------------

error: unresolved symbols remain

error: errors encountered during linking;

Please help me

I think those missing symbols are from DSP/BIOS. The video scaling example comes with a BIOS CDB file. Did you convert it to a TCF file first before building?

Thanks Ki,

now I have converted video.cdb to video.tcf and added to my project.

Now I am getting this type of error:

Aarti,

Lines 43 and 44 of the file <bios_DM642.tci> configure the DM642 cache memory size, therefore your recently converted .tcf file may be trying to modify these values.

Although you should be allowed to do that, since the target configuration is defined according to your hardware, I don't fully comprehend why the DSP/BIOS utility tconf is spawning this error. My guess is the conversion process from CDB to TCF was not done properly, therefore I think you will have better help from the BIOS experts in the BIOS forum. I will move this thread there, ok?

Hope this helps,

Rafael

Hi Rafael,

Actually in C:\ because of authentication failure those lines of bios_DM642 couldn't be modified. so, now I have changed the location of ccs so that issue is resolved.

another problem I am facing with videocfg,s62 file,which is specified in .pjt file, My understanding is saying that this file has to generate on its own(correct me if I am wrong), but in my case it is not being generated and I have to add it to my project from scaling example folder.and then it's giving me these errors:
