Hi Team ,

I have an kernel code base wich we want to add to our existing Yocto BSP .
we have Yocto 3.1 BSP for x86-64 architecture .

We have an ARM board for which we use to compile using traditional way

Any pointer as to how to approach creation of new BSP for ARM-V8.2 Cortex-A55 , 64bit little endian
- Like is there any existing sample Yocto ARM-V8.2 BSP which i can look .
- Pointer to add new architecture to existing Yocto BSP
- Any other suggestion will be helpful

So basically i want to add Kernel for ARMV-8.2 to our Yocto BSP ( which we have checked for x86-64 )

Thanks ,
Ashish

Hi Ashish,

Nvidia Jetson Xavier NX uses an ARMv8.2 CPU
https://elinux.org/Jetson_Xavier_NX

You can look in meta-tegra layer how is it done:

https://github.com/OE4T/meta-tegra/blob/master/conf/machine/jetson-xavier-nx-devkit.conf
https://github.com/OE4T/meta-tegra/blob/master/conf/machine/include/xavier-nx.inc
https://github.com/OE4T/meta-tegra/blob/master/conf/machine/include/tegra194.inc

require conf/machine/include/arm/arch-armv8-2a.inc


That uses yocto tunning from
https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/conf/machine/include/arm/arch-armv8-2a.inc
