Hello Bertrand,

I succeeded in building the core minimal image with dunfell and its compatible branches [except xen-troops (modified some files to complete the build)].

But I face the following error while booting.

(XEN) ****************************************
(XEN) Panic on CPU 0:
(XEN) Timer: Unable to retrieve IRQ 0 from the device tree
(XEN) ****************************************

The reason for that problem *might* be in the arch timer node in your device tree which contains "interrupts-extended" property instead of just "interrupts". As far as I remember Xen v4.12 doesn't have required support to handle "interrupts-extended".
It went in a bit later [1]. If this is the real reason, I think you should either switch to the new Xen version or modify your arch timer node in a way to use the "interrupts" property [2]. I would suggest using the new Xen version if possible (at least v4.13).
