AER demo gets stuck

Hi there,

Boards: EVM5515 and EzDSP5535

AER: aer_c55l_cpuv3.3_obj_17_0_0_0_Win32

CCS: 5.5

I am trying to evaluate AER demo project. It compiles but when I run that it always gets stuck. The last message in the console is Start data processing...

I looked through the code and identified that it never goes out from the function aerSimFread(). Inside of the function is numRead = fread(tempIoBuf, buf_size,

AERSIM_FIO_SIZEOF_WORD, file); So it reads two times and that gets stuck.

How it can be fixed?

Thanks.

Hi,

I have a few questions regarding this problem:
1. how did you compile the project?
2. were you running on CCS simulator or EVM?
3. were you running the out of box example or did you make any changes or use your own input files?
4. did you try the pre-built executable packages\ti\mas\aer\test\lnkr\c55l\aertest_c55l.x55L?

Thanks,
Jianzhong

Hi Jianzhong,

Thank you for reply.

1. Just imported the project, manually corrected paths in project settings and pressed Build.

2. Running on 5515EVM.

3. It is the out of box example. I did one change. It complained that could not find AER_SIM_ROOT_FOLDER. I just wrote path to the folder:

#define AER_SIM_ROOT_FOLDER "c:/ti/aer_c55l_cpuv3.3_obj_17_0_0_0/packages/ti/mas/aer/test/"

4. No. Will try now.

Jianzhong,

Just tried to launched pre-built executable packages\ti\mas\aer\test\lnkr\c55l\aertest_c55l.x55L. Result is the same. I can see the same messages in the console, where the last one is Start data processing... Than it gets stuck.

Stan,

Can you check folder packages\ti\mas\aer\test\vectors\out? Do you see rxout.pcm and txout.pcm? What's the size?

Regards,

I can see them. The size is 0 bytes.

Can you try to run it on CCS simulator, e.g. C55xx Rev3.0 CPU Functional Simulator? I just ran it and the demo example finished successfully.

Thanks,
Jianzhong

No, I did not. I will try but I am more interested in running it on the real core. It turns out that vectors/inp/fe_16k.pcm is not open properly because this function numRead = fread(tempIoBuf, buf_size,AERSIM_FIO_SIZEOF_WORD, file); does not work correctly.

I added new target configuration - C55xxRev3.0 CPU Functional Simulator, turned off Detect Page Wrap around and launched it. Than I loaded pre-built c:\ti\aer_c55l_cpuv3.3_obj_17_0_0_0\packages\ti\mas\aer\test\lnkr\c55l\aertest_c55l.x55L. After that a message appeared:

Can't find a source file at "M:\TI_MAS_AER_17_0_0_0_bldforge\dsps_gtmas\ti\mas\aer\test/aersim/aersim.c"
Locate the file or edit the source lookup path to include its location.

Than I pressed RESUME(F8) and it started initializing in the same way as it was under debugging. And again the last message in the console was Start data processing...

The size of the files rxout.pcm and txout.pcm are zero.

Hi Stan,

I used CCS 5.5 in Windows 7 and had no problem running the prebuilt test code. What version of CCS are you using?

Thanks,
Jianzhong

Jianzhong,

It is good to know that demo is working. My environment is WIN7 and CCS 5.5.0.00077. Any suggestions why it does not work?

Did you change anything in the project? I imported it right from here c:/ti/aer_c55l_cpuv3.3_obj_17_0_0_0/packages/ti/mas/aer/test
Can it be Windows related thing?

Thank you
Stan

I have tried everything and still no luck. Tested it on 3 different PC. I was using functional simulator and pre-built aertest_c55l.x55L. Please watch video to get more details about the problem: drive.google.com/open;authuser=0

What is wrong?

Stan,

I have exactly the same version of CCS and also use Windows 7. It's pretty strange why it works in my PC but not in yours.

I didn't open the project, but just loaded the prebuilt and hit F8. It then ran to finish. Maybe you want to try that?

Jianzhong

Jianzhong,

Just tried that. Project is closed. I just launched simulator and loaded pre-built. It also got stuck at the same place.

It works! I have just re-installed CCS. Do not know for sure what was that but now I have no complains. Thank you, Jianzhong
