<li>Then you will be prompted whether you need to display the kernel configuration interface. If you do not need to modify the kernel configuration, select the first one. If you need to modify the kernel configuration, select the second one.</li></ol>

<li>If you choose to display the kernel configuration menu (the second option) in step 3), the kernel configuration interface opened through '''make menuconfig''' will pop up. At this time, you can directly modify the kernel configuration. After modification, save and exit. Yes, compilation of the kernel source code will begin after exiting.</li></ol>

<li>If you do not need to modify the kernel configuration options, when running the build.sh script, pass '''KERNEL_CONFIGURE=no''' to temporarily block the pop-up of the kernel configuration interface.</li></ol>{| class="wikitable" style="width:800px;" |-|

<li><p>If the following error is prompted when compiling the kernel, it is because the Ubuntu PC terminal interface is too small, causing the make menuconfig interface to be unable to be displayed.
