Dual boot options for ROCK64?

[easyfab]

I try to do a dual boot with Libreelec based on maal example.


My partitions

Code:

lsblk -o NAME,LABEL,PARTFLAGS,FSTYPE,SIZE
NAME         LABEL       PARTFLAGS FSTYPE  SIZE
mmcblk0rpmb                                  4M
mmcblk0boot0                                 4M
mmcblk0boot1                                 4M
mmcblk0                                   58,2G
├─mmcblk0p1                                3,9M
├─mmcblk0p2                                 64K
├─mmcblk0p3                                  4M
├─mmcblk0p4                                  4M
├─mmcblk0p5                                  4M
├─mmcblk0p6  boot        0x4       vfat    112M
├─mmcblk0p7  linux-root            ext4   48,4G
├─mmcblk0p8  LE_SYSTEM   0x4       vfat   1000M
└─mmcblk0p9  LE_STORAGE            ext4    8,8G

And my extlinux.conf

Code:

TIMEOUT 150

DEFAULT kernel-4.4

MENU TITLE Rock64 boot options


label kernel-4.4
   kernel /Image
   initrd /initrd.img
   fdt /dtb
   append earlycon=uart8250,mmio32,0xff130000 rw root=LABEL=linux-root rootwait rootfstype=ext4 init=/sbin/init coherent_pool=1M ethaddr=${ethaddr} eth1addr=${eth1addr} serial=${serial#}


LABEL LibreELEC
   LINUX /Image
   FDT /rk3328-rock64.dtb
   APPEND boot=LABEL=LE_SYSTEM disk=LABEL=LE_STORAGE quiet console=uart8250,mmio32,0xff130000 console=tty0

I have copy LibreELEC Image,SYSTEM and rk3328-rock64.dtb on LE_SYSTEM partition.  and take example from LibreELEC extlinux.conf

I boot from SPI (using rock64_write_spi_flash.sh )
But I have kernel panics when booting with DEFAULT LibreELEC. I don't know how to select menu when booting I see nothing on screen.

No problem to boot Ubuntu .

Has Someone some ideas ?
