Question

Hello

 

i've updated the kernel from the legacy to the dev using the procedure

 

To make sure you won’t run into conflicts within newly installed packages, remove them all before upgrade:

 

 

1
2
aptitude remove ~nlinux-dtb ~nlinux-u-boot ~nlinux-image ~nlinux-headers
aptitude remove ~nlinux-firmware ~narmbian-firmware ~nlinux-$(lsb_release -cs)-root

Proceed with install:

1
2
3
4
apt-get install linux-image-dev-sun8i linux-dtb-dev-sun8i linux-headers-dev-sun8i
apt-get install linux-u-boot-orangepiplus2e-dev linux-$(lsb_release -cs)-root-dev-orangepiplus2e
apt-get install armbian-firmware sunxi-tools swconfig a10disp
reboot

 

but i'm able to see just one core

Just did it on Orange Pi Zero, followed by


 

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

and it did not help:

17 minutes ago, tkaiser said:

IIRC there was something with u-boot's sec/nonsec boot mode (for legacy sec is needed while nonsec with mainline for SMP bring-up -- or vice versa)?

Yes, and for recent images it was stored in /boot/armbianEnv.txt, but in recent nightlies and future images it is solved with u-boot patches.

I'm not using Armbian, but had same issue and google brought me here as I was facing same issue.

As mentioned tkaiser, issue was for me in u-boot script(/boot/boot.scr), where I had: "setenv bootm_boot_mode sec" and I've compiled sunxi-next kernel. When I changed it to: "setenv bootm_boot_mode nonsec" and recompiled it with "mkimage -C none -A arm -T script -d boot.cmd boot.scr" it gave me 4 online cores after reboot.

Hope it will help others facing same issues.

Hi guys,

 

nothing from mentioned workarounds works for me:

Do you have any other hints?

Try to replace (and recompile) a boot script as well. Get it from here https://github.com/armbian/build/blob/master/config/bootscripts/boot-sunxi.cmd and add rootdev=UUID=xxxx to /boot/armbianEnv.txt if you don't have rootfs on your SD card (logs are also partially broken and can't see that)

... and remove packages which you don't need:
linux-dtb-dev-sun8i
linux-image-dev-sun8i
linux-image-sun8i
linux-xenial-root-orangepipc

I did but it still doesn't work :(

I am also running out of ideas :( I assume you see all four cores when booting from a clean build? ;)

Yes, clean install shows all 4 cores. Would you mind checking my system? I can give you SSH access if you send me your ssh key.

@Lukas Hejmal thanks for you tip, worked for me.

 

@danman I also have the Line with `machid=1029` in my `armbianEnv.txt` but 4 cores are shown.

 

verbosity=7
console=both
machid=1029
bootm_boot_mode=nonsec
disp_mode=1920x1080p60
overlay_prefix=sun8i-h3
rootdev=UUID=74434014-190f-406c-9b73-2c99c49383ba
rootfstype=ext4
overlays=analog-codec spi-spidev
param_spidev_spi_bus=0

 

Long Story:

 

Hardware: OrangePi PC

 

* long time ago I installed a jessie image

* lots of hacking was done on that board

* pulseaudio in jessie get a mess so updated to stretch repo

* pulseaudio needed a newer kernel!!

* lots of trying with new kernel/old kernel and SPI for another project

* done in the end nearly the same as `mariel` but with `*-next` and and a dist upgrade to stretch it booted \o/

* but surprise only 4 cores

* read this thread and now 4 cores \o/ nice
