CCS: CCS3.3.81.6 DSP/BIOS5.31.02

Hello Stefani

Stefani said:

I tried porting it to CCS5.5 but I had trouble compiling and linking, probably because of the DSP/BIOS?

What are the build errors you see when trying to build the project?

Stefani said:

Where can I download CCS3.3 base package?

If you wish to stay with CCSv3.3, please start a private conversation with me.

Thanks

Hi Stefani,

I sent you a link to the latest CCSv3.3 image.

Let me know if you still wish to also try using CCSv5.5. If so, I will pull in a BIOS expert to look at the above error.

Thanks

Ki,

Thank you for sending me the link to CCS3.3.  I downloaded, unzipped, and installed it. 

When I "Build", I get an error for the tconf:

line 355: Reference constraint violation:HST:RTA_fromHost.bufseg.MemberTest(L0SARAM) failed

The tcf file's line where it failed has the following:

bios.L0SARAM.space = "code";

If I removed that then the tcf compiled but I get a linker error (I don't think I can remove the line, I was experimenting).

What can I change to make it work?

Thank you.

Stefani, I will bring this thread to the attention of the BIOS experts.

Thanks

Stefani,
does your BIOS 5.41 installation have a directory 'xdctools'? I have BIOS 5.42, which can be downloaded from here, that has that directory and I use tconf.exe from there, and I get the correct importPath. Can you post a screenshots of the Project Properties->CCS Build->TConf and Project Properties->CCS Build->TConf->General Options windows?

Thanks Ki.

So I tried installing it on an old XP machine (instead of virtual XP machine that I use).  It said that CCS needs target configuration.  I am not sure what I should do there.  It is a custom board, with TMS320C2812 and I don't have an emulator that will work (I have XDS200 which I use to flash the board).

Can I ignore it? 

Thanks.

Stefani,
I can't see which device you are using, but it seems it is something from the 28xx family. I think that somewhere in your script you are allocating the buffer for L0SARAM for Host Channel Manager (HST) to L0SARAM. The instruction will look similar to the one below, or L0SARAM is the default value for that buffer and there won't be any instruction specifying that property.

bios.HST.instance("RTA_fromHost").bufSeg = prog.get("L0SARAM");

At the same time, the instruction you quoted above is trying to allocate L0SARAM for code. You can't use L0SARAM for both at the same time. You may want to allocate the buffer for HST to a memory object that is reserved for data. You would find an appropriate one if you opened your script in gconf, the visual configuration tool. With gconf, only memory objects reserved for data can be allocated for the HST buffer.

XDS200 is not supported with CCSv3.3. Do you actually need debug support with CCSv3.3? Of it is just to build the project only (and you use some other technique to load/flash the code to your board)? If you only need build support then it is not essential to have the specific target configuration. You can likely just use the 2812 device simulator.

Hi Stefani,

I'm able to build one of the BIOS 5.42.01.09 examples without any errors in CCS 5.5.  One difference I noticed is that the tconf script I'm running is the one in bios_5_42_01_09/xdctools, whereas you are running the one in c:/ti/xdctools_3_23_03_53.

Could you check your project settings under Build -> Tconf and see what the command is?  I have "${BIOS_CG_ROOT}/xdctools/tconf" -b

Best regards,

Janet

No I do not need debug support with CCSv3.3.  On one machine I chose F2812 device simulator, but I still get the same errors.

On my virtual machine, I launch setup again, chose F2812 device simulator, tried to build again, same errors.

For just build, it doesn't really matter what target you are using.

Regarding the error, it is out of my expertise. I defer to Sasha's post earlier.

Thanks for replying Sasha.  The device I am using is TMS320F2812.

The lines in .tcf file I have with bios.HST are only the following:

bios.HST.HOSTLINKTYPE = "RTDX";

bios.HST.OBJMEMSEG = prog.get("M0SARAM");

bios.HST.HOSTLINKTYPE = "NONE";

The lines with L0SARAM are:

bios.MEM.BIOSOBJSEG = prog.get("L0SARAM");
bios.MEM.MALLOCSEG = prog.get("L0SARAM");
bios.TSK.STACKSEG = prog.get("L0SARAM");

bios.L0SARAM.len = 0x1000;

bios.L0SARAM.createHeap = 0;

bios.L0SARAM.space = "code";                    // *************** this is the problem line ******************

if (bios.MEM.LOADTRCDATASEG == prog.get("FLASH")) {
bios.MEM.LOADTRCDATASEG = prog.get("L0SARAM");
}

if (bios.MEM.SYSMEMSEG == prog.get("FLASH")) {
bios.MEM.SYSMEMSEG = prog.get("L0SARAM");
}

If I have the problem line, I cannot open it in graphical Edit.

If I comment out that line (put // in front of it), then I can open Config Graphical Edit, and under Input/Output, HST has Object Memory M0SARAM and Host Linked Type NONE.

Good, then I am OK with the target configuration.  Thanks Ki.

When you open the configuration in gconf, can you see "RTA_fromHost" and "RTA_toHost" under HST? If yes, can you look at their properties?

Sasha, this is with CCS5, correct?   See attached files.  It seems my files did not attach properly.

From Tconf:

Command:  "${XDC_CG_ROOT}/tconf" -b

Command-line pattern: ${command} ${flags} ${inputs}

Summary of flags set:

-Dconfig.importPath="C:/ti/bios_5_41_13_42/packages;"

From General Options:

"${BIOS_CG_ROOT}/packages"

Is there 'xdctools' directory in C:/ti/bios_5_41_13_42? If yes, change the Tconf command to "${BIOS_CG_ROOT}/xdctools/tconf" -b.

Now back to CCS5.  No, there is no xdctools directory in bios_5_41_13_42.  I am downloading bios 5_42_01_09 now.

I still have trouble getting this to compile,  I get a lot of warning messages.  

Since I have it compiling and linking in CCS3.3, I am going to move on and probably try to port the code all the way to CCS 9.  I will open a new thread when I am looking into it.

Thank you so much for everyone's help!
