Linux: apps building for linux_ NullSrc :use case

mohammed zakariya ansari

Tool/software: Linux

Hi folks,

i am building the nullsouce use case for linux+bios, i have done following changes for the same and build was successful.

my changes:

1. in cfg.mk updated NDK_PROC_TO_USE=ipu2

2. chains_nullSrc_Display.c modified the size as

#define ENCODE_MAX_FRAME_WIDTH (1280)

#define ENCODE_MAX_FRAME_HIGHT (720)

my observations:

1. EVEM board boots properly

2. application runs properly

3. when i run the nullsrc use case i see assert ( ASSERT (nullSrcLink_tsk.c|NullSrcLink_fillData|202)). please refer attached log for your reference.

Need help to go forward.

Thanks,

Mohammed

Hello Mohammed,

When does assert happens? While running the use-case or when you start network tools? Did you check if the file format you are using is same as of configured in the use-case?

Thanks Prasad for the quick reply,
Assert happens while running the use case.
File format is same as configured.

Mahammed,

Just to confirm, you are keeping the input file in the SD card right? or have you modified current use-case to take input from network?
In case you want to use network you would need to use different use-cases (under network use-cases menu)

Hello Mohammed,

From the error log, the assert is happening in the NullSrcLink_fillData function of links_fw\src\hlos\links_a15\nullSrc\nullSrcLink_tsk.c.
This looks due to incorrect index file generation.

Are you generating header and data files correctly?

Please check if e2e.ti.com/.../2364032 helps?

Hello Prasad,

Thanks for the update, Kajal is my colleagues :) and i have already discussed and tried the same. i am using the same index file and image that has run in bios, i am running the same use case for linux+bios.

Appreciate the lead any more.

Thanks,

Mohammed

Mohammed,

Can you please put a breakpoint in the failing line in CCS and see if frame size is zero? and why is it zero?

Also please share use-case main file and the your header and data files to try on local set up.

Hi Prasad,

I am not using CCS/Debug, i am directly running the program.
Let me check other way why the frame size is zero,i will update you for the same.

One more thing you can try is use the header and data files with working BIOS use-case.
Also compare null src link configuration (done in use-case main) in the linux usecase to bios use-case.
