TDA2EXEVM: TFDTP: ERROR: PBM_alloc() failure...exiting

Hi Stefan,

I have forwarded your question to an expert for comment.

Regards,
Yordan

Hello Stefan,

Can you please share your NDK buffer allocations in NDK_config.cfg? Meanwhile we'll try to reproduce this issue at our set up.
Also if i may ask, any special reason you want to use TFDTP Rx link instead of Null source link with TFDTP?

It would be better if i could use the NullSrc with the TFDTP, that would be preferred option. However, when i use that option, the data is being dropped. I can see that network tools is immediately sending out data which i can catch over wireshark, the load on
M4-1 jumps on ~80 percent but i cannot see anything more on my display. As for the data statistics, it is as follows:
New data Recv = 10
Driver/Notify Cb = 9.96
In Recv FPS = 10
out FPS = 0
Out Drop FPS = 10
all else = 0.0

Does this mean that i have a bad IPC or link?

NullSrc works normally when its not in FTDTP mode...

The problem with PMB_alloc occurs only with the TFDTPRx + Display

Bellow is the full NDK_config.cfg, only change made to the original is var enableStaticIP = 1.

Hello Stefan,

Sorry for late reply. Wanted to try both use-cases on my set up first. I could run both use-case without any issues.
Here are few points to be noted.

1. TFDTP Rx+ Display works in streaming mode, so this needs rebuild of tools with TFDTP_TX_STREAMING_MODE to 1
2. For null source with TFDTP use-case, default binaries can be used. If tools are rebuild with streaming mode, this use-case will fail. It needs TFDTP_TX_STREAMING_MODE set to 0

I believe in your case with Null source TFDTP, data is dropped because you are using streaming mode Tx binary. Can you please confirm?
Also have you made any changes in the use-case? Current fps is configured to 10 in this use-case, though with TFDTP you can get ~30fps.
I would suggest to try first with 10fps and then increase.

The null source with TFDTP acts like this - When TFDTP_TX_STREAMING_MODE is set to 0, I get the same PBM_alloc error as I mentioned. In that case, I get only upper half of my first frame shown on my display and it is green. Network tools keeps sending out data frames, but nothing is changed on my display (because of that allocation problem).

I am not working on EVA board anymore because it has some issues and I can not ping it every time... I have switched to board that we have developed (TDA2xx)... I can run all network use cases on it without any problems. We haven't changed anything that could influence TFDTP.
Can you tell me, what SDK are you using and what is your setup? Did i miss anything during TFDTP configuration (please see the first post again)?

Is it possible to set the null source (without TFDTP) to work on 30fps?

Hello Stefan,

Are you running PC tools on Linux machine? If not can you please run it on Linux PC?
If you are already running on Linux machine, we can have webex session to debug this further.

Is it possible to set the null source (without TFDTP) to work on 30fps?
>> If you are running networking stack on IPU then you can't get 30fps; moving it to A15 you can get.

Hey Prasad,

sorry for the late response, I was trying various scenarios.
I was working on windows and now I have switched to linux after which I've concluded that it is the network tools on windows that causes that allocation issue.
I have tried putting an appimage both built in linux and in windows on my board and to run network tools from linux and TFDTP works without any problems.
What could cause this bug in windows network tools? Our entire team works in windows so this could be an issue.
