Dual boot options for ROCK64?

[Tony32]

ayufan just got SPI working last week - this holds the promise of multibooting different OS'. I wouldn't expect this anytime super-soon, but now at least the possibility is real.

Well, that is good news. Even if I have to wait a bit. Thanks.

What works for me:


/boot/extlinux/extlinux.conf

Code:

TIMEOUT 30
DEFAULT kernel-4.14

MENU TITLE Rock64 boot options


LABEL kernel-4.14
   kernel /boot/Image-4.14
   fdt /boot/rk3328-rock64.dtb-4.14
   append earlycon=uart8250,mmio32,0xff130000 rw root=/dev/mmcblk0p1 rootwait rootfstype=ext4 init=/sbin/init coherent_pool=1M ethaddr=${ethaddr} eth1addr=${eth1addr} serial=${serial#}

Not really sure what you would like me to do with this, but I think the first bit of code is the OSes/kernels you can chose from on boot? If that's the case, neat! As mentioned earlier, if you could make a how-to, that would be lovely
