Hello, i have custom board with am335x, but very similar to evm3358 starter kit.

i have updated the kernel from repository using git? downloaded latest Graphics_SDK_4_10_00_01

and build

make BUILD=debug OMAPES=8.x all

make BUILD=debug OMAPES=8.x install

before it i had mounted file system as

sshfs root@192.168.0.200:/ ./Mounted

in rules.make i fill in the following

HOME=/home/user/

# Set Toolchain path (ex /home/user/toolchain/arago-2011.09/armv7a)
CSTOOL_DIR=/home/user/bin/codesourcery/bin

# Set Tool chain prefix (ex arm-arago-linux-gnueabi- )
CSTOOL_PREFIX=arm-none-linux-gnueabi- ARCH=arm

# Set kernel installation path ( ex /home/user/linux-04.00.01.13 )
KERNEL_INSTALL_DIR=/home/user/Documents/linux-am33x

# Set Target filesystem path ( ex /home/user/targetfs )
TARGETFS_INSTALL_DIR=/home/user/Mounted

# Set installation folder
GRAPHICS_INSTALL_DIR=$(HOME)/Documents/Graphics_SDK_4_10_00_01

it builds and installs without errors

but when i run 335x-demo on target i get

root@am335x-evm:/etc/init.d# ./335x-demo

Hi,

Can you please try building graphics SDK with PM_RUNTIME=1 option?

This should solve the problem you are seeing.

Please see links below for more details -

Thanks,

Prathap.

Thanks a lot, i had found another topic also

http://e2e.ti.com/support/arm/sitara_arm/f/791/p/284135/991101.aspx

PM_RUNTIME=1 has helped me, but there was another error. I have tried more earlier version of sdk Graphics_SDK_4_06_00_02 with this option and everything is alright with driver registration and OGLES demos/

but what do i need to watch video?

when i try script that was with am335x evm? for example runH264Dec.sh

i get

root@am335x-evm:/usr/bin# runH264Dec.sh

Hi,

Good to know that PM_RUNTIME=1 helped you. Also thanks for marking the verified answer.

You did not see this problem with Graphics_SDK_4_06_00_02 as PM_RUNTIME option was introduced with 04.09.00.01 to support the linux runtime PM framework.

The script (runH264Dec.sh) you are referring to is not part of graphics SDK.

Please raise a separate thread so that the concerned experts can help you on that.

Thanks,

Prathap.
