Update kernel

omerpoly

Hello,

 

I'm new in kernel programming in embedded linux systems.

 

For the beggining, I'm trying to update the kernel version from 3.14 to 4.0.9 of Debian distribution.

For boot I'm using U-Boot, and my microcontroller is imx6 (ARM architecture).

 

I have the sources for the 4.0.9 kernel and for u-boot.

 

For my understanding, there is 5 stages to these procedure:



1) u-boot – build & compile

2) u-boot – burn to SD card

3) Kernel – build & compile

4) kernel – burn to SD card

5) boot

 

At the end, the process doesn't work.

I'm not familiar enough with this subject to start debug and find the problems.

 

My question is:

 

Is there a way to know if i did the first/second/third/forth/fifth stage correct and if it's works?

 

Thanks a lot,

Omer.
