Compiler/DRA77P: Customize Yocto File system

Intellectual 520 points

Part Number: DRA77P

Tool/software: TI C/C++ Compiler

Hi all,

I'm trying to build Yocto file system. But it take too long to complete compile and really need a lot of memory.

From Processor SDK Linux Automotive Software Developers Guide, there is only one option - dra7-evm.

Below are my question:

Q1, Is there any other minimal file system for DRA7?
Q2, Is there a way to customize file system?
Q3, I don't need some packages like Qt. Can I disable it? If yes, How to disable?

Any help would be appreciated. Thanks.

Hi,

There are several ways to customize the file system and build a minimal image.

Please refer here for some useful references: https://training.ti.com/sites/default/files/docs/Customizing-Yocto-Based-Linux-Distribution-for-Production.pdf and this thread which already outlines the procedure: https://e2e.ti.com/support/processors/f/791/t/756204

If you still have questions please let us know.

Regards

Karthik

Hi Karthik,

According to https://e2e.ti.com/support/processors/f/791/t/756204

I follow VisionSDK_Linux_UserGuide.pdf section 3.7 to build Linux Vision SDK file system. Below is one of instructions.

2. Apply the patches present in the linux-kernel-addon/fs-patches/yocto/meta-glsdk folder of Vision-SDK to the tisdk/sources/meta-glsdk folder in the yocto repository.

But I can not find meta-glsdk in the ti-processor-sdk-linux-automotive-dra7xx-evm-5_00_00_01/yocto-layers/sources.

Does it rename to meta-ti? But there is no recipes-graphics/gbm/libgbm_10.0.0.bbappend.

Did I check the wrong folder?

Can these patches apply into PLSDKA 5.00.00.01/yocto-layers ?

Hi,

The patches are present in the Vision SDK installer. Please make sure that you download that package and check inside the respective folder.

Also, note that the patches will not be directly applicable. I just want to provide you a reference to how one could customize a filesystem to make it to a smaller size. So use them as a reference only.
