capitaine mabrouk38

hello all and happy Ramadan

i am actually using the MCSDK_3_00_03_15 ( linux 3.10.10 RT7) in my EVMK2H . and i want to execute a program in my linux (ARM) with the Real Time Priority.

so is there a way to configure this in the embedded linux that i use?

thank you.

Hi,
Did you enable RT support in linux kernel by using the following defconfig file ?
arch/arm/configs/keystone2_fullrt_defconfig

so is there a way to configure this in the embedded linux that i use?

Other than configuring RT support in linux, no need to do anything with linux kernel.

After enabling RT support in linux, you can run your real time C application in user space.

Example:

Hi,
This config file is used when you configure the kernel with RT support.

Please follow the below procedure to build RT linux kernel.

cd linux-keystone

Export the linaro toolchain.

make distclean ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

make keystone2_fullrt_defconfig ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

make uImage ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

make dtbs ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

Please refer to the following TI wiki.
