I have xillinux OS (based on ubunutu 12.04.LTS) installed on my hardware (microzed Board). I will add UART Lite IP Core(after removing xillybus lite core IP in device tree) using vivado after which I need to rebuild my kernel after editing the config-3.12.0-xillinux-1.3 file in /boot folder. My question is how do I rebuild the existing kernel on the hardware after making changes to the config file
http://www.wiki.xilinx.com/Uartlite+Driver
This is the page above that I am referring to where they say that:
To enable the uartlite driver in the linux kernel you either have to integrate it or build it as kernel module (.ko). You can enable it with:
make menuconfig
---> Device Drivers ---> Character devices ---> Serial drivers ---> Xilinx uartlite serial port support
make menuconfig - I have to enter this command on the OS running on my hardware in the /root/boot/.config folder to enable it ?
What does , ---> Device Drivers ---> Character devices ---> Serial drivers ---> Xilinx uartlite serial port support THIS MEAN ? I have to change directory ?
The other option as per the link posted above is to add certain lines as below to the config file, for which I would use the nano editor and then save it with ctrl+X and then Y.
# integrate into the kernel
CONFIG_SERIAL_UARTLITE=y
# build as loadable module
CONFIG_SERIAL_UARTLITE=m
But they say that, "After that you of course have to rebuild the kernel and deploy it to your Zynq device."
Where zynq is the hardware I am running my OS on. What commands do I have to use to rebuild the existing kernel on my hardware after making changes to the .config file ?
So, after rebuilding the kernel with the changes above, I just reboot to observe the changes ?
I was referring to this link,
http://www.thegeekstuff.com/2013/06/...-linux-kernel/
So, in order to compile the exisiting kernel on the hadrware and build it, I edit the .config file in nano and save it.
Then, I type "make" in the same folder as config.
Then, I type "make modules" in the same folder
Then I type make modules_install
Then I type make install
Then I reboot the system to see the new kernel installed.
Is this the right way of doing it ?
Currently in my boot directory, there are 4 files. One config file and 3 .dts files. After rebuilding the kernel, this might change ?
