No chance to test myself for pi4 (because of lack of hardware yet), but I believe
BR2_LINUX_KERNEL_DTB_OVERLAY_SUPPORT=y is needed for an 64-bit kernel, see
[1] and [2] for pi3...

Peter

Hello Peter,

Indeed it is needed.
I don't know how i got a working serial on rpi4 without it...
Thanks for the feedback, I will propose a V3 to fix that.

Regards,
Arthur
