Hi,
I enabled CPU hotplugging from kernel configuration for evmk2h. Image was successfully built. I booted with the new image and was able to see file /sys/devices/system/cpu/cpu3/online. I wrote 0 to this file to disable a core. But soon after that kernel crashed.
Regards
Abdul Basit
Hi Abdul,
I don't think that this is not due to mismatch of kernel and filesystem.
Just I've fetch the kernel from TI git and did build.
git clone git://git.ti.com/keystone-linux/linux.git linux-keystone
make keystone2_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-
Copy the K2HK dtb and uImage to tftp and did NFS boot.
Here is the complete log.
