How i configure jetson TX2 from ubuntu 16.04 to rt-linux

277920103 · April 9, 2020, 9:59am

i use /usr/src/kernel/kernel-4.4/scripts/rt-patch.sh to patch rt-linux,command:cd /usr/src/kernel/kernel-4.4 ./scripts/rt-patch.sh apply-patches,always default enter,make menuconfig,select fully preemption kernel,save,exit,make zImage,report error
may i need rebuild atfer fix error?or may i operate error? i think the pack should stable and suit the current kernel source,should not report error,
whiceh issue with me ?

rt-patch not support for the J3.x, Please using the J4.3 or J4.4

ShaneCCC · April 10, 2020, 5:41am

J4.x is kernel 4.9 instead of k4.4

277920103 · April 10, 2020, 6:07am

Yes, current the rt-patch for k4.4 may have problem.

Please have a new topic for the visionwork. Also please have much detail information should be speed up to figure the root cause.

Hi @277920103 ,

Please start a new topic for this. This topic will focus on rt-linux discussion only.

For r32.3.1 there is ./kernel-4.9/scripts/rt-patch.sh

277920103 · April 22, 2020, 8:16am

is it must make in ubunt 18.04 of JET4.3? i think it also can make in 16.04? because the source package is fully and the RT-patch is suitable the kernel

277920103 · April 22, 2020, 8:25am

i make kernel failed after patch the rt-patch use R32.3.1 on ubuntu18.04 of JET4.3,the error log of “make zImage” is follow:

i think it should have yet make succes before commit this sources,if where i configure error?

Please follow this document to build the kernel Image.

i have install visionworks and VPI sucess access unconnect usb and reboot TX2,
thanks.

i make kernel sucess to follow this step of this link,but make kernel failed use "make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j4"after patch the rt-patch and make menuconfig
whether not necessary to make menuconfig and config the fully preemption kernel? i see CONFIG_PREEMPT_RT_FULL in .config under $TEGRA_KERNEL_OUT after use “make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig”
even not necessary to patch the rt-patch?
