How to have ti81xxvo.ko load at boot?

Please follow below procedure to generate ti81xxvo.ko :-

make ARCH=arm

CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabiti8168_

evm_defconfig

$ make ARCH=arm

CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabi- uImage

$ make ARCH=arm

CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabi- menuconfig

You need to make the configuration changes as per user guide ( DM816x_AM389x_VPSS_Video_Driver_User_Guide.pdf). After configuration give below command to generate the ti81xxvo.ko.

make ARCH=arm

CROSS_COMPILE=PATH_TO_TOOLCHAIN/bin/arm-none-linux-gnueabi- modules

After boot copy the module to your file system and insert the module

Insmod ti81xxvo.ko

Hi,

can you verify you have init.d/modutils.sh & init.d/udev scripts in ,target_filesystem/etc directory.

if yes, place the <modules>.ko inside /lib/modules/<kernel_version> directory so that  they are automatically load relevant moduels at boot-up

follow below steps to install manually.

1. copy <module>.ko to target filesystem system

2. from here, You can make a symbolic link of your module to the standard path, so depmod will see it and you'll be able load it as any other module.

sudo ln -s /path/to/module.ko /lib/modules/`uname -r`
sudo depmod -a
sudo modprobe module

Hope this helps

Yes, both scripts are present.  I tried putting in a symbolic link, that installs the module just like insmod, but when I reboot the EVM, it isn't there anymore.  How do I get ti81xxvo.ko to install when the EVM boots?  It is getting placed into the target filesystem but isn't getting loaded.

where have you placed the files.

can you paste the linux boot log where it mentions about depmod.

There is no mention of depmod in the boot log.
