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



For the beginning, 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?



My main problem is:



The kernel that loaded is 3.14. The boot is work but the kernel that loaded is version 3.14, but it loaded without ethernet and other drivers. I think this is the default kernel. *If I don't interrupt the U-boot, nothing is loaded. I followed this tutorial:

  • Do you get any error message? Can you get any sort of output from the boot process? How do you program the new kernel? (Where is it read from?) It is likely that you can do just steps 3–5 if you are upgrading the kernel and the microcontroller already has uBoot and the old kernel there.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
