XU4 kernel 4.9

I see from Odroid forum this has been released - will this be available for DietPi?

If not tempted to buy a second one with recent price drop:

Main reason is I read that video transcoding has improved a lot.

After reading the Odroid forums all evening I decided to manually install the 4.9 kernel from here:

But - unbootable system. Restored from backup and all working again.

Hopefully Fourdee will have some insight into this.

Hi John,

It looks like the 4.9 kernel is still in early devolpment/testing stage. I think the best thing to do would be to report any issues directly to this thread: http://forum.odroid.com/viewtopic.php?f=146&t=26007

I was unaware Meveric released the 4.9 kernel, let me test it on my system. I’ll also message Meveric so he can see your results.

Hi Fourdee,

I was possibly a bit hasty last night as I didn’t want to go to bed and leave a broken system - hence the restore.

I missed the step of attaching a monitor to see what was going on would you believe!

I assumed it wasn’t booting - nothing on router, no SSH, no cloudshell display.

I’ll try it again tonight.

John

Tried again this time with monitor attached (kicking myself for not doing this yesterday) - device booted but no LAN. Hard to do anything without this.

John

Gutted lol.

The following may be helpful for debugging this (and reporting it to Odroid as an issue):

dmesg | grep eth

Or save to boot, eject SD and read from PC :smiley:

dmesg > /boot/debug.txt

HI Fourdee,

I’d love to get this kernel working but restoring to an eMMC is such a hassle - having to take Cloudshell case to bits and getting a PC to read the eMMC to restore is hit or miss. Done it twice now. Maybe a better idea is to set up a dual boot and experiment on an SD.

Or buy a second XU4 :slight_smile: Given I have an unused case and PSU having upgraded to Cloudshell this is tempting :slight_smile:

John

Aye, must admit, the price reduction is very tempting :wink:

guys,

Any luck with the 4.9 kernel on the XU4? solving ethernet issues

@johnvick did you tried wlan maybe that works for you and you’re be able to run the 4.9 kernel

Today meveric released a new compile for the kernel http://oph.mdrjr.net/meveric/kernel/XU3/4.9.x/

I’ll try it again later today and let you know.

In this thread running at the odroid forum, they mention this exynos5422-odroidxu4.dtb flattree file. I wonder whats the difference between the xu3 and xu4 versions. Is the ethernet performance gain related to it? (once it contains the specifics about the hardware).

@johnvick
Maybe it is easier for you to grab a sd-card to test/debug the upgrade, and keep your eMMC safe

I may just do that - but not right now having had a pig of a day yesterday installing a new eMMC and restoring from backup. All working now but I don’t feel inclined to dismantle the device again. May do at the weekend. I’ve been watching the Odroid forum with interest too.
