I have build the kernel 4.14 from source and could install it in my 820c successfully. But unfortunately it was not able to detect the sd card. From the forum, I came to know that, this issue with the sd card is fixed with later kernel versions. So I am trying to build and install the integration branch by checking it out using the command
“git checkout integration-linux-qcomlt” .
I could build it successfully and could make ’ boot.img’.
I did “sudo fastboot flash boot boot.img”
After this I tried rebooting the board,but nothing is happening (Board is not coming up).
I could boot the board with the pre build images,
$sudo fastboot flash boot boot-linaro-buster-dragonboard-820c-221.img
$ sudo fastboot flash rootfs linaro-buster-alip-dragonboard-820c-221.img
But the kernel is 4.14.
Could you guys help me with why I am not able to boot with the newly built kernel?
