can I dd your xfce image straight to an eMMC card?

anyway, you just need to change the name of the root partition in /etc/fstab and /boot/uEnv.txt

I does work from microSD card.  I just needed pay attention to the console

Code:

Copy info from "Call trace..." to a file(eg. dump.txt), and run                command in your U-Boot project: ./scripts/stacktrace.sh dump.txt                                                                                                Resetting CPU ...                                                                                                                                              ### ERROR ### Please RESET the board ###

My bad.

This is deeply impressive:-


If I want to recompile my own kernel do I do it with this source https://gitlab.com/pine64-org/quartz-bsp/rockchip-linux ?
and if yes, is it the "quartz64" one (branch?) or the "develop-4.19" or one of the others?

can I dd your xfce image straight to an eMMC card?

anyway, you just need to change the name of the root partition in /etc/fstab and /boot/uEnv.txt

I don't have /boot/uEnv.txt did you mean /boot/extlinux/extlinux.conf ?
I changed the entry in extlinux.conf to root=UUID=d14648ed-fd3c-4e85-b9fd-619cfcc8d206

here are my logs:-

got it working on eMMC
I just edited extlinux.conf thusly

Code:

root@quartz64:~# cat /boot/extlinux/extlinux.conf LABEL slarm64 LINUX /Image FDT /dtb/rk3566-quartz64-a.dtb APPEND root=/dev/mmcblk2p3 ro rootwait rootfstype=ext4 init=/sbin/init loglevel=4 earlycon=uar t8250,mmio32,0xfe660000 console=tty1 console=ttyFIQ0,1500000n8

I wonder if there is a way to put UUID in the root=
