I fail to make Graphics-SDK work in DM8148 DVR-RDK environment

Sharon Golan

Hi.

Our setup is Mistral DM8148 EVM with Video-Security card. In this setup we manage to run
the DVR-RDK demos and also to put graphics-overlay using Qt via FBDev.

We now try to compile the Graphics-SDK and run the OpenGL demos (at this state OpenGL
1.1 is sufficient).

Regarding versions: we use DVR-RDK 4.0 and the latest Graphics-SDK 4.10.0.1.

After setting what needed according to the "3D Graphics SDK User's Guide", the compilation
passed successfully.

But when we run the "38xx-demo" script it aborts with the following failure:
"/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=34)"

During search in the forum for similar problems, I found 2 posts that seemed relevant.
According one of them I tried to compile the Graphics-SDK with Power-Management
enabled, but it did no solve the issue. From the second I learnt that there is a possiobility
that some software modules in DVR-RDK and Graphics-SDK might not match, but I failed
to comprehend what specifcaly might not match and how to resolve the issue.

I'll appreciate any insignt/guidance.

Thank you.

I'm putting below the full sequence of shell messages when executing "38xx-demo":

Based on what I read in the forum, I tried to work with Graphics-SDK 4.08.00.02 (instead of the 4.10.00.01 ).
I get the same failure.

We now have Graphics-SDK 4.08.00.02 working with DVRRDK 4.0.0.3 .

The steps that were found to work for us are the following (seems that order is important):
- Compile u-boot
- Compile uImage
- Compile modules
- Install modules
- Compile Graphics-SDK
- Making SD-card(we boot from SD card at this state)
- Compiling the DVR-RDK

We compiled Graphics-SDK with : --es6.x FBDev=yes and X_ORG=0 all

Boot arguments were set according to the Graphics-SDK quick installation guide (http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide)
so for DM814x we set:
mem=128M vram=50M ti814xfb.vram=0:48M,1:1M,2:1M

step no. 1: u-boot compilation

change to the u-boot build dir:
cd /…/DVRRDK_4.00.00.03/ti_tools/linux_lsp/u-boot/uboot-dvr-rdk

and make:
make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- clean
make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

The result is a “u-boot.bin” file.

We used a utility that “takes” MLO, u-boot, uImage & boot.scr and write them to SD card. Before this write it partitions the SD to have 2 partitions: “boot” & “rootfs”.

It's possible at this stage to verify “mkimage” has been created. This file will be used in next step (kernel build). First thing is to change dir to

/.../ti_tools/linux_lsp/uboot/u-boot-dvr-rdk/tools

ls –l mkimage

The “mkimage” is used by the kernel makefile during kernel build. it's path should be added to PATH.

step no. 2: Kernel compilation

do:

cd DVRRDK_04.00…/ti_tools/linux_lsp/kernel/linux-dvr-rdk

make clean

make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- clean modules uImage

Now change directory:

cd arch/arm/boot

Here you’ll find the “uImage” which is the compilation result.

Next step is to install the modules:

cd DVRRDK_04.00…../ ti_tools/linux_lsp/kernel/linux-dvr-rdk

make ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- modules_install INSTALL_MOD_PATH=/…/ DVRRDK_04.00…/target/rfs_814x

the result is the following library :
/.../rfs_814x/lib/modules/2.6.37/kernel

step no. 3: Graphics-SDK compilation

cd /…/Graphics_SDK_4_08_00_02

make clean

make BUILD=release OMAPES=6.x FBDEV=yes SUPPORT_XORG=0 all

make BUILD=release OMAPES=6.x FBDEV=yes SUPPORT_XORG=0 install

Now you have 2 folders under “/.../DVRRDK_04.00…/target/rfs_814x/opt” :
“gfxlibraries” and “gfxsdkdemos” .

step no. 4: making SD-card to boot from

build an SD having 2 partitions: Using the boot & kernel generated in former steps together with the content of rfs_814x/* as FHS :
boot partition - in it MLO, uboot (built in step 1) & kernel (built in step 2).
rootfs partition - in it the file-system copied from “/.../DVRRDK_04.00…/target/rfs_814x/”.

Last thing to do is to copy “boot.scr” to the SD-card's boot partition.

step no. 5: Compiling DVR-RDK

Now we need to compile the DVR-RDK to have the vpss & frame_buffer kernel modules.

cd /…/DVRRDK_04.00…./dvr_rdk
make -s all

We also need to change the “load.sh” script. This can be done by saving “/…/DVRRDK_04.00…./dvr_rdk /bin/ti814x/load.sh” as “load_SGX.sh” and edit it to change the line handling insmod of ti81xxfb.ko to be:
insmod ./kernelmod/ti81xxfb.ko vram=0:48M, 1:1M, 2:1M

Running the OpenGL demos

- “cd” to DVRDK folder
- execute “./init.sh” and after it “./load_SGX.sh” (this is the modified load).
- change directory to: "/etc.init.d”
- execute “./38xx-demo”
- cd to the OpenGL demos dir (in this case Open1.1) “/opt/gfxsdkdemos/ogles”
- run one of the demos, say “./OGLESSkybox”
