I am using BPI-F2S board. and i am trying to rebuild kernel. Currently i am using ''2019_11_29_debian_10_buster_mate_desktop_beta_bpi_f2s_sd_emmc_img" os version in the board.
Now i want to add more functionality like GSM integration for that need to rebuild kernel.
I have already downloaded kernel resources using system->preferences->Hardware->Armbian config.
Now trying to build kernel using below steps:
1). kernel source is directly downloaded in /usr/src/ directory.
2). Make changes in few files like option.c and more.
3). Run “sudo makeconfig” command and select all required options.
4). Run “sudo make -j4” command and done successfully.
5). Run “sudo make bzImage” and done successfully.
6). Run “sudo make modules” and done successfully.
7). Run “sudo make modules_install” and done successfully.
8). Run “sudo make install” and done successfully.
9). Run “sudo update-initramfs -c -k 5.9.15” and done successfully.
10). Run “sudo update-grub” and done successfully.
But not getting proper result also not change in anything “uname -r”.
Before build “uname -r” result is 4.19.37-BPI-F2S-Kernel and after process complete.
Please share your valuable suggestion.
