Developing OpenGL ES 2 on DM8168

I have downloaded the lastest EZSDK available for DM8168 (5.05,.02.00). Since I need to develop OpenGL ES 2 I also downloaded gfxsdk 5.01.01.02 (Is the right package?).

I can find the source of OGLES2 demos running in EZSDK.

I want to rebuild the package, once modified Rules.make to match my directory tree I run

make OMAPES=6.x

but I get an error:

ubuntu@ezsdk:~/Graphics_SDK_5_01_01_02$ make OMAPES=6.x

I cannot find sgx-omap.h neither in Graphics_SDK_5_01_01_02 directory nor in ti-ezsdk_dm816x-evm_5_05_02_00.

where am I wrong? do I downloaded the right files?

Hello,

The EZSDK doesn't include the source code of the demos. Graphics SDK releases contain the source code for all OpenGLES demos and kernel mode SGX driver.

That was not my question. I sensed that I had to download another package.

I wonder how to rebuild that examples, since I have the error described in previous post.

The file sgx-omap.h seems to be missing. I cannot find it in any TI directory. So I think I'm doing something wrong. But what?

best regards

Max

Hello,

Are you following this guide:

yes,

but I am very confused: in the Realease Note of Linux-Graphics-SDK-05.01.01.02: http://processors.wiki.ti.com/index.php/RN_5_01_01_02#Pre-requisites I found:

Pre-requisites

Kernel(Linux PSP) versions supported or used for validation

AM335x & AM43x -
- Tree: git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
- Branch: ti-linux-3.14.y

Toolchain

Linaro 4.7.3 hardfp toolchain(arm-linux-gnueabihf-) was used for creating this release package.

Nothing is specified for DM8168, but for DM8168 I have downloaded EZSDK 5_05_02_00 that support kernel 2.6.37 and Codesourcery as toolchain.

Is that right? so I wonder if the right kernel is 3.14 or 2.6.37, if the right toolchain is Linaro or Codesourcery.

And the problem remains: the missing of sgx-omap.h

what I need is a step by step quick guide for installation and rebuild examples

best regards max

Max,

You can upgrade to 04.06.00.03, which is the last release tested for 814x/816x:

04.10.00.01 is only build tested for 814x/816x

Linux-Graphics-SDK-05.01.01.02

Starting from version 5, Graphics SDK is applicable only for AM335x/AM43x, can not be used with DM816x.

The linux kernel for DM816x is 2.6.37. The toolchain for 4.10.00.01 is arago. The toolchain for 4.06.00.03 is arago. The toolchain for 4.04.00.02 is CodeSourcery 2009q1.

Pavel
