TDA4VM: TIDL Graph init fail

Frank DU

Part Number: TDA4VM

Two applications exist for image collect and image processing in one TDA4

1 、app_1 image collect app used nodes (3 senor nodes ; 3 capture nodes ; 3 (viss +aewb) nodes ; 2 ldc nodes ; 1 miscoa node ; 1 display node ) in one graph ,The application captures the image and sends the address to the Tidl processing application.

2 、app_2 Tidl processing app ，Take the image, process the image 。

（app_1）image collect app Can run normally. The error is TIDL Graph initialization error by the tdil processing process（app_2）

Our memory partition is configured as follows

Marked in red is the modified configuration used

We tried to make adjustments and couldn't fix the bug;

请看下面工程师的回复。

> Could you please share the full application logs (along with the logs of "source ./vision_apps_init.sh")?

> Are you making the memory changes with the help of the tool gen_linker_mem_map.py available in the vision_apps of the SDK?

If not, I would suggest you use this tool to do the memory related changes so that it would create all the relevant dependencies.

> Have you made the relevant changes on the linux side (i.e., in the .dts file) and generated .dtb file and replaced the same in the SD card?

Thank you for sharing the logs.

I wasn't able to find this error in the logs in the app_2.log file. Is it not seen anymore?

I see there are many errors, such as regarding graph parameters and related to create of GraphScalar? Are these known issues?
Could you clarify where the issue is currently?

Just to summarize your issue.

You have 2 Apps. I believe it is 2 graphs in the same context, right?

CASE 1: If yes, First App (i.e., First Graph) is running "1 senor nodes; 1 capture nodes; 1 (viss +aewb) nodes; 1 ldc nodes; 1 miscoa node; 1 display node"
and the second App (i.e., Second Graph) is running "TIDL node".

In the above scenario, everything is working fine, right?

CASE 2: The issue occurs when you changed the First App (i.e., First Graph) to 3 senor nodes; 3 capture nodes; 3 (viss +aewb) nodes; 2 ldc nodes; 1 miscoa node; 1 display node
In this case, you are seeing the below error in Second Graph i.e. in the TIDL node

VX_ZONE_ERROR:[ownGraphCreateNodeCallbackCommands:983] Node create user callback command at index 0 failed
62.959650 s: VX_ZONE_ERROR:[vxVerifyGraph:2024] Create node callback commands failed
62.959663 s: VX_ZONE_ERROR:[vxVerifyGraph:2109] Graph verify failed

Please let me know if I have understood your issue correctly?

If yes, few queries from my end are follows

1. Are both graphs in the same context?

2. What are the graph parameters you are using here?

3. The change which you have done, i.e., 3 capture nodes, 3 viss etc. May I know what is the usecase? We could control multiple sensors with 1 capture node and 1 viss node (As done in the multi-cam demo in the SDK)

4. In CASE 1, where everything is working, are the memory changes present there?

or are the memory related changes mentioned in the description a part of changes made during CASE 2?

Could you please tell me which SDK version is this issue seen?

So, regarding the memory changes you mentioned in the description, I see that you have increased "TIOVX_OBJ_DESC_MEM" and reduced the same amount of memory from "DDR_SHARED_MEM" right?

In this case, could you confirm that you have made the extended region of TIOVX_OBJ_DESC_MEM as non-cachable?

If you are using SDK 8.2 or lower, you would have to make this change in vision_apps/platform/j721e/rtos/mcu2_0/r5_mpu.xs
If you are using SDK 8.4, you would have to make this change in vision_apps/platform/j721e/rtos/mcu2_0/j721e_mpu_cfg.c

Could you make this change and confirm if you are seeing the issue?
