Part Number: TDA2PXEVM

Hi,

I want to make a large number of Frame buffer objects (FBOs) in my OpenGL code.

However, when I execute my program on TDA2P EVM, the out of memory (OOM) linux error occures and program

will be killed.

I want to expand memory resource assigned for SGX in TDA2P to avoid OOM.

How can it be done?

Thanks

Hi Koji,

Can you provide some additional details regarding this

- What TI baseline release are you using

- What do you mean by large number of FBOs - how many of them do you want to create and what are their resolutions.

Thanks,

Gowtham

Hi Gowtham,

I am using TDA2Px EVM (VisionSDK v03.07.00).

Size of FBOs are 1920x1080. I want to create 10 or more FBOs.

I have created 6 FBOs and got OoM error.

Thanks,

Koji

Hi Koji,

Please increase cma to 128MB in your uenv.txt and give a try.

Default setting is visionSDK is 64MB, this seems insufficient .

Thanks

Hi Koji,

Upto what number of FBos it is working with 128MB of CMA?

Can you please share some information on how to reproduce the issue and the what OpenGL applications is used for this?
