Re: xen cache colors in ARM



Hello Stefano,

I would like to try a xen cache color property from this repo  https://xenbits.xen.org/git-http/xen.git
Could you tell whot branch I should use ?

Regards,
Oleg

I am familiar with the zcu102 but I don't know how you could possibly
generate a SError.

I suggest to try to use ImageBuilder [1] to generate the boot
configuration as a test because that is known to work well for zcu102.
